Thread: does riding a bike burn as much fat calories as running?

i would like to run but it kinda hurts my knees, and im only 16 so im worried bout that. if you could tell me if riding my bike for about an hour and a half burns as much calories as an hour long run, or whatever the comparison may be that would be great. thanks

You a loser if you cant even handle a mile run without your knees hurting... push through the pain you mind can do anything i now run 5miles a day when i get home i can barley walk let alone take a shower i lay on the shower floor as i relax
