There will be a Kids 1K run (under 10).  All kids will get a bib just like Mom & Dad.  The race is FREE for the kiddos if mom or dad is registered and you can register on line at no charge.  Sorry no shirts for the kiddos, but they can be purchased on line during registration. 


Fox River Park is full of mature woodlands, wetlands, and many species of wild flowers. You’ll feel like you’re in the northern woods of Wisconsin without leaving Waukesha County.  The 5K / 10K course runs through the forest canaopy with a surprising number of elevations changes.

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.

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 and enjoy our free fresh fruit bar at the finish line.



The shirts are gendar specific, dry wick and those registered the Friday one week prior to the race are guaranteed a custom race shirt.  After that shirts will be available while on line supplies last. Any extra shirts will be distrubuted after the race on a first-come, first-serve basis.  The FEMALE shirts run small!
