so, how often do you change your route on the commute? I've managed to peg out a 5 mile commute with 360 ft of climbing, a 6 mile commute with 380 ft and a 8 mile with 640 ft! unfortunatly my work doesnt have a shower so i need to try and keep the sweating to a minimum but as my fitness improves (and i get bored!) i will stray further afield! i have done a lunchtime 5 mile loop too with 400+ foot of climbing! i love working on a hill and living in a dip!!!
