Don't feel like signing onto yet another site but I have 64 miles this week in December (21 for tues doesn't count).
Naturally I get 107mi or so every week, just for commuting. Sometimes I'll ride out to the bike shop to pick something up in which case it'll be an additional 12 miles each time.

I'll also hit about 50 on the weekend Sat ride and now that I'm beginning some training I'll be slowly upping that number.

Have fun, it's a great way to stay motivated!
