There are a ton of clubs out there. One of my buddies from Iowa just moved out there and has been hitting trails most weekends with a few different clubs.
This should be fun! Usually during summer me and a group of about 8 guys hit the trails every weekend. We have only been 3 times this winter but, as soon as it warms up we know that every sat or sunday there will be a run!
We also have meet and greets here in denver every other months. Usually at buffalo wild wings or twin peaks!!!
