How long do you commuters go WITHOUT riding? Esp. those with longer commutes? I'm not up to making my commute both ways yet (40-mile roundtrip), but I try and do it one way 3-4 times/week. When I do the back-to-back trips (ride home and in the next morning), I find myself pretty worn out after that ride in - although I'm bouncing back and recovering quicker now than I did earlier on. I give myself a day or two off, but am worried about taking too much time off and losing any conditioning.

Also on my 2 days off - I really think I should get out there and do at least a 20-miler to keep it up. Plus, I WANT to get out there, I NEED to get out there! Help! I think I'm addicted to my bike riding high!!!
