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.

Participants with mobility issues have completed Ultra Challenges in the past on crutches and wheelchairs, and those with sight loss can also participate with a guide.

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.
