Ultra Challenges are physical events, where you can choose to walk, jog or run a distance of 10km –50km. The Event Organisers welcome participants of all abilities who are confident in their ability to participate, however must ensure everyone is clear on the requirements and accessibility restrictions of the route. 

While each challenge covers different terrain and landscapes, you can typically expect steep climbs and descents, the necessity to cross stiles, and uneven pathways subject to weather effects such as mud and dust.

If you have any accessibility concerns or questions you can contact Action Challenge directly to discuss requirements and they'd be happy to support you.
