I cycle to work, 10 miles each way. Plus try to do 25 to 50mile rides one day at the weekend.

I wouldn't say I was that fit though, and though my thighs are pretty rock, I'm not muscled elsewhere. I'd love to also have the energy to swim at lunch, but I'm too busy and tired generally.

Cycling is good as it is actually a bit quicker than the tube, and is a great place to clear my head.

I agree that cycling doesn't really make you fit as much as it seems (it's an incredibly efficient mean of transportation!). It is well worth it for me though, for that "head clearing". Biking is pretty awesome: you sort of relate much more to your surroundings/city than in a car, you have time to look around and interact, it's great.

I do miss simply walking sometimes too though (it does feel painfully slow when you get used to cycling around!), but if the distances are large (not too large o/c) the bike can be your best transportation friend.
