The Course
Both race distances take you across diverse terrain using gravel tracks, grassy paths, and woodland trails.
The start and finish are set on a wide gravel section, with steep grassy banks providing a great vantage point for spectators. Runners will embark on an 8km loop from the starting line before returning to begin the next segment. The remaining 13km of the half marathon leads through dirt trails in wooded areas, open paths ways, and speedy gravel roads.
Although not a multi-lap race, you’ll revisit certain sections during the half marathon, adding a sense of familiarity as you progress.
The 10km route shares the same path until the 9km mark, where it then heads back toward the finish line.
Join us for a fun-filled day of running and make some lasting memories!
