its hard to say i know for sure i did 10 miles to work and back and 14 to the school and back. i didn't take direct routes though i zigzagged there so i'd hit the hardest hills.

thanks for the info i just rode my bike for 2 hrs. the first 40 mins were 20 minutes to work and 20 mins home from work. 15 minute break then rode again for an hour and 20 minutes. man it felt good. how much calories is usually burned in an hour biking? any guesses?

that is true. this summer i'm going to the beach and it has lots of hills. i want to go up one of the hills and see if i can make it. i think i'm going to try 30 miles uphill ;-)
