The Addo Elephant Trail Run is the only triple ultra distance trail running event in South Africa, offering a choice of 100 Mile, 76km or 44km distance ultra-trail runs.

Originally founded in 2005, it is also South Africa's oldest 100 Mile ultra trail race.

The 100 Mile distance was resurrected in 2016 with a new and challenging route that takes runners from one end of the park to the other and back again.

Both the 76km and the 44km races take place on sections of the same course, just with slightly less elevation gain.
