That is just GREAT! You're so fortunate to have found a group you can ride well with--I think that really makes a difference.

I'd been cycling solo for a few years before I got hooked up with a club--well, actually the slow sub-group of the club. But I've improved more in the year of riding with this group than in several years on my own.

Have fun and don't forget to post here when you've done your 20-miler!
