September 22–23, CMU’s Walker Field

The Greater Grand Junction Sports Commission is proud to introduce a brand-new, thrilling fitness event: The River City Rumble.

If you’ve never met a burpee you didn’t like, aren’t afraid of a clean and jerk and live to wall ball, this is the event for you!

Join us September 22-23 on the Colorado Mesa University campus for this exciting competition.
