I'm currently working on a cycling route for myself and the Elder Son the next visit to Japan to visit in-laws. The first attempt involved about 1800m of climbing and 165km, which I've now managed to exchange for 900m climbing in about 200km: Notice the great leap northwards to find a slightly lower pass through the hills. Essentially everything that is green on that image is lumpy. Taking the need to acclimatise into account, and that Elder Son is a keen cyclist but more interested in seeing stuff than powering out the miles, I'd expect to achieve about 60-80k a day, so this would take 3-4 days. As an introvert I'd be happy with this as it means the time spent surrounded by Beautiful Wife's lovely, but very large and extroverted family is reduced a bit... Anyway, I was wondering, to what ahem, lengths to you go to to avoid hills? or do you just power up them and enjoy the view and descent?
