Over 500 people took part in the Ultimate Survivor challenge at the Old Foundry just outside Letterkenny.
It was a hugely successful event with two obstacle courses, one over 5k and one over 10k.
It featured a mixture of running , jumping, climbing and crawling, with plenty of mud and water.
Those taking part were full of praise for the organisers of the event.
The survivors got a commemorative t-shirt - and the package also included an after party in the Orchard Inn, and also a pass for The Pulse.
Futher video coverage will follow.
