Race Day Experience
Fresh Fruit Bar
Finish your race and refuel at the WTA Fresh Fruit Bar.
Our post-race finish area includes:
- Fresh fruit
- Pickle juice
- Lemonade
- Iced tea
- Cucumber water
Grab something cold, refuel, hang out, and cheer on the runners still coming down the trail.
This is a Cupless Series
As runners, we want to protect the places where we run. Using and throwing away more than 100,000 disposable cups each year doesn't make much sense, so we've eliminated cups from our aid stations.
The aid stations aren't going anywhere. Water and sports drinks will still be available. Just bring your own reusable cup, bottle, hydration pack, or other hydration gear.
You can also use our bag drop areas for nutrition and hydration supplies.
Enjoy the trails. Stay hydrated. Leave the disposable cups behind.
Park Entrance & Parking
Waukesha County and the Wisconsin Department of Natural Resources charge entrance fees at applicable parks. Annual and daily passes are available. Check each individual race page for park-specific information.
Waukesha County park passes must be purchased online.
Parking is limited at many of our parks. Follow park staff directions for overflow parking and give yourself plenty of time. If you're fashionably late, you're still late. Be early!
