I love riding in the fall and winter for a few reasons:

Other riders (who don't ride all winter) see you as a die-hard, which is fun for me because I'm so not. I wouldn't ride if it wasn't fun.

There's little chance of getting passed when you're the only one out there.

You warm up without getting sweaty.

The roads are aren't as bad (at least around here) as you'd think. The salt and sand can be a bummer because you have to clean your bike more, but that's a great excuse to buy a winter bike. There will be days where you just won't be able to ride because of the weather, but there are lots of beautiful sunny days with clear rodes that are just perfect if you're dressed right.

You feel so much better than you do during a winter spent bundled up indoors, eating too much holiday junk, and getting too little sunlight.

For me, a big perk is that traffic is far less around here in winter. Riding without the summer crowd is a luxury. I'd rather be a little cold than have tourists constantly cutting me off.
