235 km a day on my Bike Friday

A couple of weeks ago I did my longest ride on the Bike Friday yet – 235 km in a day, across the mountains west of Tokyo to a lake near Mt Fuji during the cherry blossom (sakura) season. This was part of my training for a 300 km brevet ride coming up this month. It was a beautiful ride, one of my most enjoyable so far.

Sakura (cherry blossoms) on route 413:

It took me about 16 hours, of which 14 hours were moving time. I had left home at 05:20 and was back in Tokyo at 21:20 (9:20pm). My Pocket Rocket has a Shimano hub dynamo and a Lumotec IQ Cyo headlamp which provided plenty of light on the last stretch after sunset.

Here is my route. I started from my house in Tokyo after sunrise and cycled out to the mountains some 40 km away, then followed Route 413 up a mountain valley and over a pass over 1100 m (3600 ft) high. I was climbing from virtually sea level (45 m or 150 ft) to 1.1 km high. I was cycling almost continually uphill for the first 96 km (60 miles). After 7 hours (including quite a number of brief stops for food, rest and pictures) I reached the highest pass.

More sakura:

I always want to see the remaining distance:

The exit of the tunnel at the end of The Longest Climb: It’s all downhill from here… NOT!

The shores of Lake Yamanaka at the foot of Mt Fuji, over 900 m (3000 ft) above sea level:

It can be surprizingly difficult to sea Mt Fuji (3776 m high) from just a few km away because of its frequent cloud cover. I cycled 235 km and all I saw of Fuji is this (its foot):

Almost home – at the top of the Mt Takao pass:

The humble Bike Friday Pocket Rocket:

and its crazy rider:

The ABC of distance riding: Always Be Consuming!

There is nothing exceptional about cycling this kind of distance. The key is eating and drinking sufficiently. Most people who first try long distances become exhausted not because of insufficient training, but because they simply eat and drink too little. The energy reserves in your body only last so long. Three meals a day will not cover the continuous energy use of long distance riding. You need to consume about 200-300 kcal per hour and sufficient liquids.

I carried water in two bottle holders, which I refilled whenever I could. Throughout the day I ate: 7 bananas, 6 raisin bread rolls, 360 g of yoghurt, a slice of pizza and several other pieces of bread. I drank about 4 litres of water, orange juice, cocoa, yoghurt drink and sports drink. Don’t worry too much about putting on weight while burning 6500 kcal. I am 10 kg (22 lbs) lighter now than I was the year before I got the bike. I’ve been dropping about one kg a month since I got the bike.

Stick to a speed you can sustain. I am not a fast rider, doing mostly 23-25 km/h on the flat (about 15 mph), with down to as little as 9 km/h (6 mph) on steep climbs, but that doesn’t stop me from going out to see nature, lots of it. I don’t go out there to set speed records, but to see the country, smell the trees and the ocean, view the rivers and mountains and bring back some pictures. Why settle for 3-6 hours when I can enjoy it the whole day?

Long rides on a folding bike

I did this 235 km ride a little over half a year after getting the Pocket Rocket, my first road bike in over 30 years. Some people are surprised that I do these rides on a folding bike. I usually point out that my house is small and a bike with small wheels is easier to store indoors. This is not just my touring bike but also my shopping bike. Almost daily I cycle to shops and carry my groceries home in a back pack. Other people may have a garage with several different bikes for different purposes, but I don’t.

The other part of the answer is that the Bike Friday is no ordinary folding bike. It has the geometry of a regular road bike and it rides like one, but also happens to fold and can even be packed into a regular size suitcase (which I’ve not done yet). It may not fold quite as compactly or as quickly as say a Brompton or Bike Friday’s smaller Tikit, bikes optimized for intermodal commuting, but it is much more suitable for going fast and far. Drop handles offer many different hand positions, which keeps your arms and back comfortable for longer. The wide range gearing with triple chain rings on the front and a 9 speed cassette at the back make it possible to climb steep mountains without too much strain on my knees but still go fast elsewhere. I love my Brooks leather saddle which keeps my bottom happy even after a whole day on the bike.

Ultimately however, it is not about the bike, but about you. If you want to ride more and further, you can do it on almost any bike. A bicycle is a tool. I’ve done a couple of 50 km rides on shopping bikes. When my son was still in Junior High School he once went on a 110 km trip (Yokohama to Enoshima and back) with some friends on a single speed folder. If you have a nice bike, you are more likely to ride it more often because it’s more enjoyable, but whether you ride it at all is still up to you. The type of bike makes no difference if you’re too lazy to ride, as I became once I got into cars, back in my 20s.

If you like longer rides, give them a try on whatever bike you have. If you find that you enjoy these tours and would like a more suitable bike, get a good one and you will not regret it.

Japan without nuclear power

Since last weekend, Japan is without a single nuclear power station feeding power into the grid, the first time in 42 years. All 50 nuclear power stations are currently off-line (this count does not include the 4 wrecked reactors in Fukushima I, which are no longer officially counted — it used to be 54 nuclear power stations).

Some of these power stations were shut down because of problems after the March 11, 2011 earthquake and tsunami. Others were taken offline one by one for routine inspections and maintenance but have not been started up again, which would only happen with the consent of nearby local governments. That consent has not been forthcoming.

Electrical utilities and the government are raising concerns about a power shortage when the summer heat sets in, which usually results in peak usage for air conditioners. Critics of nuclear power see an opportunity for a quick exit from nuclear power. Others are concerned that if the government rushes to bring power stations back online before the summer without safety upgrades and a change in the regulatory regime, a unique chance to prevent the next nuclear disaster will be squandered. If upgrades and reforms don’t happen when the memory of Fukushima is still relatively fresh, what’s the chance of it happening a few years down the road?

The utility companies are facing high costs from buying more fossil fuels for gas and oil fired thermal power stations to cover the demand; restarting the nuclear power stations would keep those costs in check. But that is only part of the reason they are keen on a restart. The sooner they can return to the pre-Fukushima state of power generation, the less leverage governments and the public have for making them accept new rules, such as retrofitting filters for emergency venting systems or a permanent shutdown of the oldest and seismically most vulnerable stations. Because of this it’s in the interest of the utilities to paint as bleak a picture of the situation as possible. Japan would be smart to proceed cautiously and not miss a unique chance to fix the problems that are the root cause of the Fukushima disaster and of disasters still waiting to happen.

What is Skipity and why is it in FireFox?

I mostly use Google Chrome these days, but still have Mozilla FireFox installed as a browser, which used to be my standard browser before I switched to Chrome.

Today I launched FireFox again and was surprised to see something called Skipity in its toolbar. Furthermore, when I tried to go to my browser custom start page (a page with my most useful links) it took me to the Skipity website. A Google search showed that Skipity comes as part of an add-on called “Download Youtube video 12.0”. I removed that add-on, restarted FireFox, opened the URL I previously had as the browser start page and went to “Tools > Options > General > Startup” to select that URL as the start page again.

Any software that changes the start page of the browser without your consent should be permanently banned from your computer!

Brand merchandise blog spam from China

Spammers in China are trying to promote websites selling counterfeit brand merchandise by posting numerous blog and guestbook spam comments with links to their sites. For example, the following domains were recently advertised by a spammer using IP address 117.28.249.102 in China:

  • 2012michaelkorsoutlet.com
  • coachfactoryonlinesoutlet.com
  • discount-christianlouboutinoutlet.com
  • longchampsaleoutlet2012.com
  • michaelkors-outletonline.com

Don’t buy from such sites. You’re handing your credit card details to criminals and spammers. Even if the sellers were to send out merchandise (which they may not bother with, as they can always claim it was impounded by customs), it tends to be of low quality. It may indeed get confiscated by customs and you could be fined.

Here are many more domains like that:

Using Sanyo Eneloop Ni-MH AA batteries to power your mobile phone

About two years ago I started using Sanyo’s rechargeable eneloop batteries. These relatively inexpensive Nickel-Metal Hydride (Ni-MH) cells are available in both AA (単3形) and AAA (単4形) sizes. They are low self-discharge cells that keep their charge for months when not in use. I’ve bought boxes of 8 cells of either type, for use in flash lights, bike blinkies, helmet lights and Bluetooth keyboards.

They are initially more expensive to buy than regular alkaline (primary) cells, but you only need to re-use them about three times before they work out much cheaper than primary cells, while you can actually recharge them hundreds of times before they start losing significant capacity.

Here are some nice gadgets that will take them, which I found sold in convenience stores here Japan.

These little cases (by alicty.co.jp) take power from two or three regular alkaline AA or Ni-MH AA cells and provide a USB port for powering mobile phones and other small gadgets with a USB power cable. As you would expect, the three cell version is slightly more powerful, looking to my Google Samsung Nexus S as an AC charger (i.e. it provides more than 500 mA). For the two cell version, the phone shows “charging (USB)” as the status, i.e. it can draw up to 500 mA. The two cell version has a USB-A socket (female) for generic USB cables while the three cell version comes with an integrated micro USB (male) cable. A very similar concept has been around for a while as the MintyBoost.

The nice thing is, if you carry enough pre-charged eneloop cells with you, you can swap cells as needed and have virtually unlimited power. You could even buy primary cells to top up if desperate (one set came bundled with each device), but they would end up costing you more than re-usable eneloop cells in the long term. I’ll carry some Ni-MH cells as spares on long bike trips or hikes, which could come in handy with these little cases.

UPDATE 2012-04-04: I also tried using this adapter with alkaline (primary = non-rechargable) AA cells and it goes through them quite rapidly. Alkaline AA batteries have a notoriously poor performance in high drain applications because of their high internal resistance. You’re much better off sticking with Ni-MH batteries such as Sanyo Eneloop!

It says on the pack that a set of 3 AAs will boost the charge state of a smartphone battery by 30-40%, i.e. it would take you about 3 sets (9 cells) to fully recharge an empty battery. Or put another way, if the phone lasts 5 hours on one charge doing whatever you’re doing, you will consume a set of fresh AAs every 100 minutes to keep it topped up. To provide 500 mA at 5 V (2.5 W) on the USB connector at 80% efficiency would draw 3 W from the batteries, or 700 mA at 4.5 V (3 x 1.5 V). At that kind of load, an alkaline battery might only supply a quarter of its rated capacity, which is normally measured at a much smaller load (which is OK for alarm clocks, TV remote controls, etc. but not high powered electronics like digital cameras or smart phones).

227 km a day on my Bike Friday

One month after my 155 km bike ride around Miura peninsula, a friend and I got up very early on a Sunday morning and cycled until after sunset. We went from Machida in the west of Tokyo to Mt Fuji and back. My total for the day came to 227 km (see route).

Why this ride? Earlier this month I had signed up for a 300 km brevet ride (randonnée) organised by AJ Nishitokyo for Sat/Sun, May 19/20, 2012. A randonnée is not a race, but individual riders do have to clear certain checkpoints within prescribed time limits. There’s an overall limit of 13 1/2 hours for 200 km rides and 20 hours for 300 km. For more ambitious riders there are also 400 and 600 km events. The most famous randonee is the 1200 km Paris-Brest-Paris that takes place every 4 years. I would have started with 200 km, but all events near Tokyo were already closed for signup, so I went for the next one up. Given that 300 km was almost twice the distance of my longest ride until then, I knew I needed some training to prepare.

My plan was to follow the 300 km route as much as possible to familiarize myself with it, but to cut it to a more manageable distance by taking a shortcut. The full route heads south from Machida in Tokyo to the Pacific coast in Enoshima (Kanagawa prefecture), from there west along the coast to Odawara, then up to Gotemba (Shizuoka prefecture) near Mt Fuji. It swings clockwise around the mountain into Yamanashi prefecture, then returns east to Machida via a route across the mountains. I decided to head north at Gotemba, replacing the long loop around Fuji with a much shorter section near Yamanaka-ko (Lake Yamanaka) to the east of the mountain. According to MapMyRide.com the shorter route would come to 213 km.

I would take the first morning train from central Tokyo out to Machida, ride several km from the station to the starting point and then follow the route. My friend Jose, an experienced randonneur (brevet rider) offered to join me and I gladly accepted. It would have been a lot more difficult without his company and experience.

We started at around 06:30, but I first needed to replace the batteries in my bike lights, attach my waterproof cue sheet to the handlebar and sort out some temporary GPS problems, which took more than half an hour. It’s better to encounter such problems on the training run than in the real time-limited ride…

As we rode along the Pacific coast from Enoshima to Odawara on this March 11, we couldn’t help thinking of the disaster that had struck the Tohoku region exactly one year earlier. The coast here is just as exposed. About 500 years ago, a tsunami destroyed a temple housing the Great Buddha of Kamakura (daibutsu) near Enoshima, almost a km from the coast. Only the bronze statue itself was left. We won’t know what will happen during the next Great Kanto Earthquake until it strikes.

After Odawara the road started climbing towards Gotemba. From there we climbed all the way to Kagosaka pass (1104 m above sea level), where we crossed into Yamanashi prefecture. It started snowing after Gotemba and persisted until we got to Fujiyoshida. We never really saw Mt Fuji, though we passed right in front of it, because of all the snow clouds. On the pass and around the lake everything but the road was covered in snow. I had to rest several times during the climb. I tried to eat and drink as often as possible in order not to run out of energy or get dehydrated (I was sweating a lot, even though temperatures were anywhere from 0C to 6C).

At the top of the mountain pass I knew we still had about 100 km to go, including two climbs of several 100 m each. I started to seriously doubt if I could really get back to Machida by bike or if I would have to catch a train from somewhere. But then we descended for something like 25 km from Yamanaka-ko and my energy came back as I could take it easy. Jose proposed a different route back to Machida that avoided some of the highest climbs and that’s what we did. There were still many climbs around Uenohara and Sagamiko, but I could manage them. Towards the end we rejoined the original 300 km route and got back to Machida around 20:00, which means I would have been within a 13 1/2 hour overall limit for a 200 km ride.

So what did I learn from this experience?

  • “There is no such thing as bad weather, only the wrong clothes” Jose told me and he was right. We were dressed appropriately and didn’t have a problem with drizzle or light snow. I was wearing mostly Uniqlo: long sleeved Heattech underwear, Jeans, a light Windbreaker. I also wore a folded handkerchief over my ears under the helmet, old socks with holes cut for the SPD pedal cleats over the Shimano shoes (“Belgian shoe covers”) and ski gloves when it was coldest.
  • I was more tired at the end of my 136 km day than after this 227 km. Eating and drinking often enough are key for long distance. Eat before you’re hungry, drink before you’re thirsty.
  • My butt hurt more on my previous saddle towards the end of the 156 km ride than the Brooks B17 towards the end of the 227 km. The Brooks is great!
  • I had some pain in my left shoulder joint, maybe from the cold and my Achilles tendons felt a bit sore the next day. I probably should have hydrated more before the ride and kept my shoulders warmer.
  • Navigating with the brevet cue sheet was more difficult than I had expected. I needed to edit the printout with bigger fonts and some translation from Japanese.
  • I logged the entire ride with the Strava Android app, with the phone connected to my dynamo hub USB charger via a Li-polymer buffer battery. The phone remained fully charged throughout and at the end the buffer battery charge state was 4 out of 5 LEDs, just like at the beginning. I could ride for days without running out of mobile power.
  • As I already learnt on my 136 km Miura ride (Feb 5, 2012), if you want to go far, start early in the morning and keep going as much as you can. You’ll be amazed how many km you can do in a day if you try!

Brooks B17 Standard saddle for my Bike Friday

A couple of days ago I signed up for a 300 km bicycle ride in May. Besides some training to prepare myself for the event I am also upgrading my Bike Friday folding bike.

The first investment has been a Brooks leather saddle. This British firm has an excellent reputation amongst long distance cyclists. On my last 150+ km ride there were two other riders with Brooks, one of them was Sarah Outen who has cycled from Europe to Tokyo on hers. The other was a friend of mine who had toured for weeks across East Tibet on his. Towards my longest ride so far I found it hard to sit on my previous bike saddle. My upcoming ride in May will be almost twice as far, so I will need to be as comfortable as I can. The B17 Standard is Brooks’ entry level model meant primarily for touring.

So far the impression is excellent: Even though Brooks saddles are supposed to take a break-in period of up to 1000 km, I have felt totally comfortable on mine from the first minute. Definitely recommended!

On the 40 km test ride I had my first puncture in 2000 km, but it was quickly fixed with my spare tube, tools and compact pump.

My second investment for the coming ride is a dynamo light, the Busch + Müller Lumotec IQ Cyo N Plus LED Front Light (175QNDi), which should be more effective than the small battery powered light that I now use. The current light is OK in town, but I wouldn’t want to rely on in the absence of street lights out of town.

More about the B&M IQ Cyo N Plus here once I will have received it and had a chance to test it!

Cycling more than 100 km a day

One year while I was in high school I cycled a total of 7500 km over 150 days (May through September), maintaining a daily average of 50 km. I lived 22 km from my school, so if the weather was OK I could get 44 km of exercise by just skipping the bus. My longest rides then were 160 km and a few days later, 220 km in a day. I had quite a few 100 km days. I’ve always preferred slowish distance rides to fast but short rides.

Recently I’ve done two rides around the beautiful Miura peninsula coastline south of Tokyo in as many weekends, each time setting a new personal distance record since resuming road cycling in October. Since buying my foldable road bike (Bike Friday Pocket Rocket), I have gradually increased my distances. I’ve been aiming for a minimum of 100 km total per week, which is fairly easy to achieve if I have at least one long ride on the Saturday or Sunday.

On November 12 I first used my bike bag for trying out the Half-Fast Cycling (HFC) Miura route on my own (58 km). Four weeks later, on December 11 I did my first ride over 100 km by combining the 60 km HFC West Park Cruise with trips to and from the meeting point in Roppongi and around Setagaya.

On Sunday, Feb 5 I joined James’ Miura “long slow distance” (LSD) ride of 140 km. I ended up doing 136 km in total. This was much tougher, mainly because the first quarter (until I dropped off to continue on my own) was quite a bit faster than I was used to. These Tokyo Cycling Club riders really are something else! But it taught me to start riding early in the morning and showed me some of the routes.


On Saturday, Feb 11 I joined the 58 km HFC Miura ride to visit Sarah Outen who is cycling and rowing around the world. I left home at 6:30 and arrived at Keikyukurihama station near the southern tip of Miura around 10:05 (66 km), a little after most others had arrived by train. The ride was great fun. The speed suited me perfectly. We took many quiet back roads and there were a good many hills. It was my first HFC ride with other folding bikes, as Jose cycled down 59 km from Yokohama on his Bike Friday Pocket Llama, on which he had cycled two weeks across East Tibet last year. There was also one cyclist on a Dahon Vector x27h.

After lunch and photos and a visit to the boat yard where Sarah is preparing for her Pacific crossing by row boat, Jose and I cycled up towards Yamato City. Unfortunately about 30 minutes into the ride I had a crash, but chose to continue despite some blood and bruises. Two hours later Jose and I arrived in Yamato in darkness. He rode home from there while I folded the bike at Yamato station and returned to Setagaya by train with the bike in the bag. The bike is OK and hopefully next week I will no longer look like I got into a bar room fight. Despite the incident the ride was much easier than the previous one. This time I stopped just short of 160 km (an imperial “century”), but I want to go further and go for 200 km. This will get easier as the days get longer and longer with Spring. I just have to keep training. Set off early in the morning, stick to a pace you can sustain and keep going!

I am now 9 kg lighter than I was a year ago, still losing a kg a month and I hardly even worry about how much I eat: I burn it anyway.

Google privacy and account cancellations

After Google announced its new privacy policy to take in effect on March 1, 2012, some people announced their intention to cancel their Google accounts. In a Washington Post online poll almost 2/3 of readers said they would cancel their accounts due to privacy changes. My answer to that is: Oh, really?

Despite what the self-selecting samples of voters on that straw poll suggests, I doubt we’ll hardly see any significant response to the new policy. It won’t even be a blip on Google’s radar screen. I think it is safe to bet that most users of the Google+ service also have Facebook accounts, whether they use them much or not. Facebook and its history of data privacy (or lack thereof) is not exactly a benign alternative to anything Google offers. I can not see people stop using Youtube, cut themselves off from their Gmail accounts and switching to what, Yahoo or Bing for web searches? The fact remains, Google may not live up to its “do no evil” credo at all times or forever, but most of us have even less confidence in companies like Facebook or Microsoft.

Google’s move is all about more clicks, i.e. more advertising revenue, which is their life blood. If they can show better targeted ads on web searches based on what you write about in Gmail or watch on Youtube, that’s more clicks that their advertisers pay for.

What worries me is if their data gets opened to the NSA, police, etc especially under the loose rules of something like the Patriot’s Act. Inside the US the constitution has been eroded further and further over the years, while its protections have never applied to most fellow humans who do not happen to be US citizens, as far as the US government is concerned. That is not a problem specific to Google latest move though. It’s something that ultimately only US voters can solve.

Mount Daibosatsu (大菩薩岳) in January

Last weekend I did my first real winter hike, up Mount Daibosatsu (2057 m) near Enzan in Yamanashi prefecture, Japan.

Last year I did two hikes on Daibosatsu with friends, but on Sunday we went back for a mid-winter hike in the snow. It’s a longish train ride from Tokyo to Enzan, where we caught a 30 minute bus ride to the foot of the mountain. In winter many of the mountain roads may be closed due to snow, so we had to hike two hours just to get to a hut which in autumn served as a bus stop for our hike then.

Because it had been raining or snowing for two days, I was wearing rain gear on top of several layers instead of the usual trousers and winter jackets. I bought a pair of crampons (Evernew EBY015 L, 6 pin, L size) as recommended by a friend, which worked really well on the snowed in mountain. There were about 30 cm of snow in the higher regions.

We left Tokyo by Odakyu line before 05:00 and got off the bus near the mountain around 08:00. After about half an hour on roads above the village we put on the crampons for the snowed in trails and forest roads. Around noon we got to the ridge (Daibosatsu-toge, 大菩薩峠) and had lunch, then headed on through the deep snow to the top to enjoy the view and take pictures. Tellingly, the only other hiker we encountered up there was wearing snow shoes. With everything covered in snow and no other sounds except for some wind, the echoes from the mountains were amazing.

Mount Daibosatsu was one of my favourite hikes last year because of its views, but this last hike was very special. Fog was sitting in many of the lower valleys all around us while all the trees were covered in thick white snow that everything had a January calendar picture feel to it, but the best was Mt Fuji. I told my friends, I would have hiked the whole 18 km for the views of Mt Fuji alone. Somehow it seemed bigger or closer than ever and the light that surrounded it was magical.

Descending was much easier than climbing, as the snow acted as a friction brake. We descended in 2 1/2 hours versus 4 hours for the climb. We enjoyed food and drinks at a restaurant at the bus stop in the company of two other hikers. I am sure this won’t have been my last hike to Mt Daibosatsu.
