I weigh 235 (haven't update the ticker) - and I have a Surly Cross Check with the knobby tires still (slicks on the way). I did a 37 mile ride with a group average speed of 17.8 mph. I finished every bit and stayed either at the start of the pack or in the middle the hole way. Near the end I finally figured out what is meant by the term 'bonked' - because suddenly my legs became like weights. Thank goodness we took a two minute break and someone handed me some 'gel' or something, and that seemed to help. I'm so sore right now I can barely move (my quads mainly) - but woo hoo We live in rolling hills too, if that makes a difference, I know it did for me.
I was the only clyde in the group. At the end, they said I was 'beastly' - I think thats a compliment. Going to go out again next Sat if I can walk by then.
