Hey sweater,welcome to singletracks dude,I'm steve32300 and am a clydesdale300 plb. at 6'2" and live in colorado where the air is thin,hahaha.And yes,I have a hard time at that weight and the steep climbs here along witht the thin air because although I'm out of shape,all that weight came from lifting weights a dozen years or so ago.And kindsa like you,I was on a prescription steroid called prednisone,quite common but steroid none the less,and I think it helped me put on that extra base of muscle weight that really takes up too much O2 especially when riding here in colorado.I was on prednisone for about a year straight,a little too long but I think I didnt care knowing what I was faced with if the medicine didnt do what we hoped it would do,,and it didnt,, so I had to have my colon removed,the whole thing and not just half like alot of others.I do have a hard time with the steep climbs here so my plan for the coming year and beyond is to give into the fact that I need to just ride in town alot more until I can get my cardio up in order to ride the trails like I want to.Also,riding has to be a intimate priority too,like fitting every chance possible of riding on one's own time in order to stay ahead of it all.I hope that we can keep exchanging the experience dude,sounds like we are kinda in the same boat medically and hobby wise,look forward to having you here on singletracks,and again welcome and have fun,it's a pretty cool website that has alot of cool people and is growing everyday..
quick,,,ride across the rainbow,before it turns to black.
