Ryan and Ryno set off on their official attempt at the Drakensberg Grand Traverse record at midnight South Africa time on Sunday. So far they've been making storming progress and at the time of writing had covered 68km and over 3,500m of vertical.
The route from Sentinal car park at Witsieshoek to Bushman's Nek border post will take them over some of the most remote and rugged terrain in South Africa. The full distance is approximately 200km.
To beat the current record of 60h 29m 30s they need to run non-stop, pushing through the night with only 20 minute stops for rest. Follow their epic challenge via live tracking.
To get an idea of what they're going through, you can also check out their POV footage above, shot during recces on the route.
