    Race Day Instructions | Parking update

    There is a $6.00 Waukesha County Park fee. Please have $6.00 ready when you get to the park. There are two lines and they will move very quickly IF you have $6.00 or a season pass ready.  Parking is available at the Family Picnic Area adjacent to Reserved Picnic Area 1. It is on the south side of the park. This is where registration, check in, and the start/finish line are located. There is additional parking at Picnic Area 2. Please do NOT park in the dog walk area or along the road. The county has changed their parking requirements and parking in the dog park or along the road will cause our permits to be pulled in the future.

    Awards ceremony is back! Please, please, please maintain social distancing at the awards ceremony. If not, we will be forced to cancel them again. Sorry, it is a permit thing.

    Please review our approved social distancing plan prior to registering for the event. Over 90% of the race is through Nashotah Park's forests and past both Forest Lake and Grass Lake. The trails are wide and are groomed year round. The 5K is one loop and the 10K is two loops. The half marathon is two laps on the outer course and one lap on the 5K course.

    2020 Runners
    Registration is open with all permits in hand! If you registered for the 2020 race, your race entry has already been deferred, but you need to claim your deferral if you want to run this year. Do it NOW because the race is going to sell out! Here is how to do it:

    2.      Click on Profile.
    3.      Under the Deferrals tab, click Complete Deferral.

For the love of all that is good and moisture wicking...

Though we try to be accurate and on top of things... Race details can change when we aren't lookin. And once in a while we simply make a mistake.
