There didn't seem to be enough cycling related threads in After Hours so I thought I would add another There's a local charity ride coming up on June 13 that I would like to enter. They have either a 50k or a 100k route and I'm trying to decide on which one to ride. I bought my road bike (a Giant OCR-1) at the beginning of April and so far have ridden about 300 miles (I'd have ridden more, but weather and yard work sometimes get in the way...) A typical ride for me is 20-30 miles so I know I'll have no problems with the 50k. My longest ride so far is 43 miles. I was pretty much dead afterwards but it was mostly my fault for riding mid-day on a hot day, not bringing along any food, and running out of water. I also probably should have had more to eat that morning before I went on the ride. So, do you think I should stick with the 50k or go for the 100k? Any training tips or general recommendations for longer rides? I'm hoping to get myself ready to ride in an MS 150 event this September before heading out to California for the HTF meet.
