Join us for a day of fun on this 1.35 mile course around Vian Lake. The paved walking trail winds through trees before turning to dirt single track switchbacks leading to the hilltop overlook. Run or walk as many laps as you can in 12 hours. Drop in for one leisurely lap or push your limits to see how many laps you can do during the full 12 hours. It’s your Saturday.

This is a self-supported FREE fun run. Donations will be much appreciated though.
