Planning to go to Izu islands for few days and Kozushima seems real nice Planning to do some Tri training too - does anyone know if bringing a road bike there with is worth the hassle ...? Road conditions etc.... ?
...to Kozushima. I've been to Oshima twice though, and the main thing about these islands (and I'm assuming all of them) is that they're hilly. Not sure how good that sort of terrain will be for "TT" training. You could try a loop route, like THIS, and follow it around several times. Otherwise, the roads to the north mostly seem to be dead-ends, and not very long either. Good luck! Travis
When you planning on going? I'll be going to Kozushima island in a few weeks for an aquathlon race, so could probably tell you more about it then.
If you're after cycling with a bit of tri training thrown in, I would highly recommend Niijima Island (one of the other 7 Tokyo Izu islands). The island is beautiful - great beaches, great cycling road, free onsens. They actually do hold a O.D triathlon here once a year, so it's an ideal island for cycling and tri training. My favourite of the islands I've been to so far.
