Limited to 1700 riders only!


We want to encourage you to enter early, as our Mountain Bike Challenge entries are capped at 1700 on the longer routes to comply with and respect the rules of the Renosterveld Conservancy on which our unique routes are hosted, so our entries are limited and they sell out fast! We will gift all our riders with their own set of arm warmers instead of a goodie bag this year, and early entry will allow you to specify your preferred size upon online entry.

Online Entries

Online entries are open on Racetec for both the MTB and Twilight Run. Follow us on social media at Facebook: STBB MTB & STBB Twilight Run and Twitter: @STBBMTB & @STBBTwilightRun for more details.


About the event

This year’s STBB4GOOD MTB Challenge and Family Day will be taking place on Saturday 12 October 2019 at Overgaauw Wine Estate in Stellenbosch. The aim of this event is to raise funds for the Miles for Smiles Foundation. Since 2017 we were able to donate R900 000 to the Miles for Smiles Foundation, which paid for life-changing corrective surgery for 162 children born with cleft lips and palates. In 2019 we hope to raise and donate even more!

The MTB race has become known as one of the “must-do” events on the MTB calendar. Our routes are enjoyable, challenging and well marked, our marshals are on the ball, we have the top class water tables in the industry, and we are told that ours is one of the best organised MTB races in South Africa. Unbelievable prizes from our generous sponsors, and loads of prizes to be won.

After the race, chill out in Bedouin tents, eat, relax and take in the view. Enjoy the food market, artisan beers and wine tasting, plus a jumping castle and arts and crafts for the kids.

About Miles for Smiles

Miles for Smiles was established to assist Operation Smile in creating awareness for the plight of children born with cleft lips and palates and raise funds to perform corrective surgery on them. The initiative has a fundamental aim, to inspire and challenge individuals to go out and make a difference in the lives of those around them, by challenging themselves to achieve the impossible. One in 10 children born with a cleft palate and lip will die before their first birthday.

Quick facts about Operation Smile South Africa:

  • In as little as 45 minutes, one cleft lip surgery can change a child’s life forever.
  • Approximately one in every 750 babies in Africa is born with a cleft lip or cleft palate.
  • Children with facial deformities who do not receive reconstructive surgery often have difficulty breathing, drinking, eating and speaking. As a result, many suffer from malnutrition, medical and psychological problems.
  • A cleft lip or cleft palate operation and follow up care costs approximately R5500.
  • Operation Smile South Africa (OSSA) was officially registered as a section 21 (non-profit) company in March 2006.
  • Operation Smile South Africa (OSSA) has treated over 1650 children since 2006.
  • Since 1982, more than 150 000 children and young adults have been treated by thousands of Operation Smile volunteers worldwide and thousands of healthcare professionals have been trained globally.

Operation Smile provides care for children in 60 countries worldwide. Nine resource countries raise funds and provide medical volunteers, while 42 program countries receive education and training and conduct surgeries. Operation Smile works in 13 countries in Africa. More than 5,000 medical professionals from around the world volunteer with Operation Smile.

About the setting

The Bottelary Renosterveld Conservancy (“the Bottelary Conservancy”) was registered as a Non-Profit Organisation (“NPO”) on 25 February 2002. Its registered purpose is to conserve the Renosterveld in its area – as such and in line with its NPO status, its core business is to eradicate alien vegetation such as bluegums, pines, “hakia” and “rooikrans” and to enhance the re-establishment of Renosterveld.

Renosterveld is not limited to Renosterbos from which its name is taken, but includes a vast number of other plants and bulbs, in total some 1700 unique plant species. As Renosterveld grows in fertile soils its natural habitat has been taken over by predominantly viticulture and only 4% of the original Renosterveld remains on small pieces of land, which are either too small or too inaccessible to farm commercially. The Bottelary Conservancy is included and forms part of the Cape Winelands Biosphere which was listed by UNESCO on 18 September 2007 – as such its conservation status is recognised internationally.

The Bottelary Conservancy launched a series of Mountain Bike Trails (“the Bottelary MTB”) during April 2011. These are very successful and contain challenging single tracks and flowing jeep tracks, which have unsurpassed 360° views of Table Mountain, Robben Island, the Stellenbosch and Helderberg Mountains and, on a clear day, False Bay as far as Hangklip!

The Bottelary Conservancy is grateful for the success of its MTB-trails which allows annual and daily permit holders to experience extended areas of Renosterveld over farms such as Koopmanskloof, Wolfkloof and Mooiplaas. Annual permit sales (currently at 1000 plus per year) will be capped at 2000 to ensure that the nature experience is retained. The only race that is allowed on this route is the STBB MTB event, for the benefit of the Miles for Smiles Foundation

As pointed out above all proceeds generated by the Bottelary MTB after meeting maintenance and other expenses are dedicated to preserving and enhancing the Renosterveld – our irreplaceable heritage!
