Helderberg & Mountain Challenge Series 2020 update

By now, you will have concluded that the Helderberg Mountain Challenge won't be happening this weekend (13 June).  The Helderberg Nature Reserve remains locked down in level 3.

Jonkershoek Mountain Challenge 2020

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 Story of the Jonkershoek Mountain Challenge

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!


Yesterday, in an events permit meeting chaired by Colonel Conradie of the Stellenbosch Municipality, the Wildrunner team was alerted to a resurgence in unrest activity in the Jonkershoek Valley.  Wildrunner was informed that this unrest is expected to escalate this coming weekend, beginning on Friday 27th April.  As such we wish to caution runners planning any training activity in the Jonkershoek Valley to make use of alternative trails until such a time as any potential threat has passed.


The Jonkershoek Valley is without a doubt one of the most beautiful mountain scenes in the Western Cape, and a popular trail running destination. Massive turrets and cliffs of orange-faced quartzite hold fortress over a collection of rambling mountain streams and waterfalls.
