Trystans Backyard Ultra

Trystan’s Backyard Ultra returns to Prairie du Chien, Wisconsin on August 15th, offering runners a unique endurance challenge in the scenic trails of La Riviere Park. This first-of-its-kind event invites participants to test their limits and join a community-driven celebration of resilience and unity.
The race takes place at dawn when the temperature is expected to hover around 22 degrees Celsius with an average humidity level of 75.7%. Runners will start on Vineyard Coulee Road in La Riviere Park, where they’ll face a course that includes grassy fields, dirt singletrack trails, and light gravel paths. The terrain features rolling hills and dense forest canopy, providing both visual beauty and physical challenge with an elevation gain of 200 to 350 feet per loop.
Trystan’s Backyard Ultra has been organized as part of Prairie du Chien's commitment to fostering community engagement through sports events. Participants can join the main event or a more casual one-loop fun run/walk, both designed for different levels of endurance and enjoyment. The race is anticipated to attract runners from across Wisconsin who are eager to experience this unique format.
The course winds through La Riviere Park’s diverse terrain, offering participants a mix of grassy fields, dirt singletrack trails, and light gravel paths. Each loop starts and finishes at the same location within the park, creating an environment where supporters gather around a central aid station providing hydration and basic fuel to keep runners going.
On race day, expect temperatures between 17.3°C and 26.7°C with typical August weather conditions featuring moderate wind speeds of up to 10 km/h and minimal risk for rainfall at only 3.2 mm expected throughout the event. The sun is forecasted to shine brightly during daylight hours.
