My wife is into this website called myfooddiary.com Anyhow, I rarely pay any attention to the stuff she rattles off that the site tells her after inputting her daily food/exercise, however - on Saturday it said I burned around 3400 calories. We did a tandem ride of 60 miles at an avg of 17.5. Does this sound right? I can't believe the calorie usage is that high. How can your body survive losing that many calories in 4 hours? I've looked at a couple other online calorie counters and they seem to concur.
BTW...if you have any suggestions as to a better piece of software or an alternative that will save me the monthly subscription to that website...I'd appreciate it.
