Hosted by Wildrunner, the BOS Sport Mountain Challenge Series, is the only one of its kind in South Africa. A tough, pure mountain running series made up of three separate races; the Jonkershoek Mountain Challenge (JMC), the Helderberg Mountain Challenge (HMC) and the Marloth Mountain Challenge (MMC). Each event consists of a Lite, Extreme and Ultra distance race. To complete the series, participants must compete in the same distance category at each race.

The Jonkershoek Mountain Challenge was launched by Wildrunner in 2011, hot off the heels of the inaugural Helderberg Mountain Challenge in 2010. The opening JMC offer consisted of 30km, 21km and 11km routes combining the best of Cape Nature & Cape Pine properties in the then relatively unknown Jonkershoek Nature Reserve. 736 runners entered the opening event and for the next eight years, this Cape classic has been a firm favorite on the trail and mountain running calendar - becoming infamous from the get go!
