whats your bike workout equivalent
I have been riding less and running a lot more lately....winter blahs I guess,and I wondered how far would I have to run to get the same workout that I get riding my usual 25 miles on the bike...for me its 9 miles of running equals 25 miles of bike riding...at the same effort level and calories burned.....what other athletic thing do you do and whats its riding equivalent time and distance
