The Karkloof100 has been designed to be spectator friendly with 9 aid stations on the 100 Miler  and 4 on the 50 Miler. Being an out and back course, each aid station other than the turning point will serve the route twice. There is an aid station roughly every 10 miles or 16 kilometers that will not only cater for runners, but also their supporters and spectators.

Spectators must view the race from designated spectator points and aid stations, which will be made known in the spectators guide.

A spectators guide with full maps, directions and information about the course and the Karkloof area will be made available through this website shortly.

No smoking is allowed at any of the aid stations, spectator points or route due to fire risk.

Spectators can make their own accommodation arrangements or pay a camping fee to stay at Wessa, Umgeni Valley. Click here for more information on accommodation.



Pacers are runners who support and run alongside 100 Miler competitors in the second half. Each runner may have up to 5  different pacers who will need to be registered at no charge.

There will be designated points along the route at which pacers can swap out.

Only one pacer may run with a runner at any time.

Pacers must be at least 18 years of age on race day and must wear a corresponding number to the runner that they are supporting. These will be supplied at registration, where each pacer will be required to sign a release form.

Pacers may not carry any hydration, nutrition or other equipment for their runner. ‘Muling’ is not allowed.

Pacers must stay with their runners at all times except in the case of an emergency.

Pacers may assist their runners with refueling (refilling or replenishment) at aid stations.

Pacers are not compulsory.

No pacers are allowed in the 50 Miler.
