With tough ‘continuous’ 100 km challenges, a 2 day ‘Daylight’ 100 km option with camping at half way, testing 50 km Half & 25 km Quarter distance challenges, and a few 10K taster events–there’s an Ultra Challenge for everyone to push themselves further!
With 15 events to choose from ranging from costal paths, lakesides, well-trodden footpaths & some tough hills there really no excuse not to join an Ultra Challenge for 2023!
Your entry includes a range of free food & drink at regular rest stops, and support from medics, marshals and massage teams. As you cross the finish line, you’ll get a glass of fizz, t-shirt, and a special medal to celebrate your achievement.
