Here's the deal, spring is here and I want to start commuting to work on my bike. I just started getting back into biking, I'm 50, out of shape (not necessarily fat, but certainly out of shape), and what little riding I've done so far has me huffing and puffing and my legs burning. Problem is, I just don't have time to do any kind of conditioning or recreational riding.

So ... I'm thinking screw it, I'll just do it. It's 14 miles one way. First and last couple miles involve nasty hills, but the middle 10 to 12 miles is perfect flat rural road. I figure if I just take it easy, give myself LOTS of time at first to do the 14 miles (1.5 hours?), walk the bike up the meanest of the hills, take rest stops etc., I should be able to just launch into the commute right? Then as this old body gets whipped into shape I'll see my commute times drop and I'll be able to peddle up the hills.

Does this sound good? Or am I stupid to even attempt such a commute without some more practice and conditioning first?
