I'm 6'- 230 I ride a TREK here in Northwest ALABAMA, mostly by myself not alot of riders here in hickville. From what I read on here from some of you, hillclimbing is tough on you. Well it's a state of mind over muscle. During warm weather whatever the temp 60- 110, 30-40 miles a day(alot of long hills)at around 20mph average. Riding by myself you have to self motivate. I have certain riders around who I've asked to ride with but the answer is tooo many hills on my rides. The way I look at it, to go downhill you've first got to climb.
