LPTR is the acronym for the Lapham Peak Trail Runners. They're a group of folks who really like trail running, and most of them are ultra-runners. I'm always excited to tell people about them because they've built a club that helps to make you a more competitive runner without the pressure that I've felt from other running clubs. Don't get the impression they aren't serious-- there are plenty of elite runners in the group.
However, it is an encouraging environment, and the general attitude is kind of reminiscent of the Hash House Harriers -- a drinking club with a running problem. Running with LPTR feels as natural as getting together to have a beer with your buddies. Sure, you're pushing yourself to get faster and stronger, but once you finish, you get to join up with the group and shoot the breeze. Of course, it helps that the lodge has a lovely cast iron stove.
