The park's trails wind through lush forests and open fields, providing breathtaking views at every turn. Participants can look forward to enjoying live music and good food after crossing the finish line, making it an ideal day out for both runners and spectators.
For those interested in the 25K Ruck Event, be prepared to carry your designated weight from start to finish while navigating the park's varied terrain. All participants who complete this challenge will receive a well-deserved finisher’s medal.
