With about an hour of sleep in the last 30-odd hours, the pair are on track to smash the standing Drakensberg Grand Traverse record of 60h 29m 30s. Track them live and to get an idea of what they've been going through, check out some of the POV footage below (shot pre-attempt).
The guys are anticipated to finish later this afternoon. We'll publish all the details as soon as they come in. Stay tuned for more.
