MY longest ride to date was about 70km round trip, to a picturesque gorge. My body handled it fine, by the end my aluminium frame had developed a host of jingle jangles. Instigated my search for, and recent procurement of, a top of the range late 80s steel frame. Picked up a serious sun burn in payment for thinking a late winter ride couldn't possibly burn me. Was very happy to enjoy zero bumsore thanks to bike shorts. Once my new bike is fully figured out and running smoothly I'll take it on a 130km round trip around a dam reservoir in the mountains of eastern Aichi prefecture.
