I'm always reading about Saturday rides on this site, but more often than not they seem to be close to Tokyo. I live in Yamato and ride around Hanbara, Miyagase Dam, Yabitsu Toge, R413 etc and am looking for someone serious about training on Saturdays. I usually ride around 100km plus, don't leave too hideously early, say around 9-10am and climb pretty hard. Is anyone out there??? Would love to join up with some other riders on a regular basis and enjoy riding in the mountains together.
