The race is chip timed by Silver Circle Sports Events, LLC.  The Wisconsin Trail Assail uses a gun start for this series keeping in line with cross country starts.  Hey that means your time starts when the gun goes off.  If you are a speedster, you should be toeing the line.

How to wear your bib

Official Physical Therapy and Running Center

Going beyond the shoe!

InStep Physical Therapy & Running Center was founded in 2003 by Tom Labisch and Bob Corby, both physical therapists, and John Ochsenwald, an athletic trainer. Their goal was to create a place where both athletes and non-athletes alike could come for physical therapy, injury treatment, rehabilitation, biomechanical evaluations, massage therapy, and custom orthotics; as well as a specialty running store where runners and walkers could be properly outfitted with the correct running & walking shoes, fitness apparel, and accessories. The best of both worlds, going beyond the shoe. 

Aid Station: 

Water and sports drinks are available on course and the finish line.  Make sure you stop in an enjoy our free fresh fruit bar at the finish line.
