What were you doing over Memorial Day Weekend? You and three of your friends could have been orbiting right loop at Tsali Recreation Area in Gone Riding's 12 Hours of Tsali race.
To me it's a perfect event: you get to enjoy a fun tailgating atmosphere at your pit (while your other friends are riding the course), and you get to race. For the more hardcore folks, there's a six-hour and even a twelve-hour solo option.
Thanks to Dave, Terri and Austin Berger at Gone Riding for putting this, and a whole slew of other cool events, together. They'll be back for the Tsali Challenge Triathlon August 29-30 (another fantastic relay event).
Here's a video. Not much trail action, but it shows the scene:
