I usually limit my rides to about 2 hours. After that, I start getting pretty uncomfortable- my seat starts to bother me and sometimes my back starts to hurt as well. I usually ride by myself because I go out pretty early in the morning so I can get home and do things with my kids on the weekend- on the weekdays, I usually use a trainer for an hour or so. I feel that I'm getting the fitness benefits from my workout regiment.
But lately, my friends that bike have been asking me to go along with them... the thing is that they usually ride 60-70 miles and ride from 4-6 hours. I really have no interest in going any more than 2 hours on any given day because it starts not being fun after that. Don't get me wrong, I do push myself on my rides, but being on a bike for that long doesn't interest me. Should I be pushing myself to ride 4 or 5 hours at a time? For those of you who have lost weight, do you find yourself riding for significantly longer times versus when you were heavier? I'm just trying to see if I'm a slacker- my 150 pound bike riding friends seem to think so (teasing me of course).
