The Hills to Henley River Run, previously the Greenbelt Challenge, utilizes Linear Park's sealed off-road trails. The course follows the River Torrens, providing a continuous route through the park's natural corridor. It traces the river's path from its inland start.
Runners will navigate the Linear Park trails, starting in Athelstone and finishing at Henley Beach. The sealed off-road surface offers consistent footing as the course progresses towards the coast. This event provides a distinct view of the river and its surroundings, ending at the beach.
