Hi, Ive been riding for about 3 months and reached about 250 miles total on my Trek 7.3 FX. I'm 27 6'4 and 290lbs. I rode a lot two summers ago, almost none last summer, and Ive been trying to get as much riding in as possible this year. Now I know I need to increase my distance by a lot, right now I ride between 10-15 miles 3-4 days a week and average 14-15 mph.
My problem is that after about 6-7 miles, my hands, feet, and butt/lower back start to get numb. I have clip in shoes and wear a cycling bib, but none of it seems to be going away the more that I ride. Muscle and lung wise I could go a lot farther, but the numbness makes me just ride straight home.
I've been saving for a new road bike and plan on buying it in November, but for the time being what should I try to get rid of the numbness. I know my size may be the issue and I have lost 18lbs so far since I started riding this year and it has not seemed to help.
Sorry for the long post, but what should I do for the time being before I get a new road bike and get it fitted to me. Should I get my trek fitted to me? New seat? Thanks for any suggestions.
