The Gem Diamonds Kalahari Challenge is open to professional and amateur mountain bikers alike and in order to ensure that the race is accessible to riders from around the world there is no qualification required.

To be eligible to ride in the full distance race participants must be at least 18 years old on 31 December of the year of the race. To be eligible to ride the lite distance event participants must be at least 16 years old on 31 December of the year of the race.

The Gem Diamonds Kalahari Challenge is deceptively tough and must not be under estimated. The short distances and lack of hills in the profile, belie the nature of challenge, as the route has a number of horizontal hills (sand patches) that will cause an increase in heart rate and the lack of long down hills, translates into riders pedalling their bikes continually and not getting time to recover. We suggest that each participant includes at least one weekend with back to back rides of equivalent distance mountain bike rides at least two weeks prior to the event.

It is every rider's responsibility to ensure that they arrive at the start with the necessary fitness level to participate.

We suggest that each rider have a full medical checkup by their doctor before taking part in the Gem Diamonds Kalahari Challenge and to supply the race organisers with the rider's medical history for the race doctors. This is essential for the planning and delivery of medical care at the Gem Diamonds Kalahari Challenge. Each rider must also sign a personal indemnity form before they are able to compete.
