EXTREME (HARDCORE + CLASSIC)

Our most challenging race, not for the faint-hearted!

Extreme, adj., exceeding what is usual or reasonable.


Held over two days, the Extreme combines both the Hardcore and the roller coaster Classic. This event will challenge the fitness and technical abilities of seasoned mountain bikers and elite riders.


Covering approx. 75km on Day 1, riders will face an elevation gain and loss of nearly 2000m with fast technical sections and single track all on Borana Conservancy. Day 2 follows the Classic route, a 60km race that has become synonymous with the 10to4.


The Extreme is not for the faint of heart. If in doubt over either your endurance capabilities or technical riding prowess perhaps the Wild, Classic or Rush is a better bet for you. You must be a seasoned mountain bike rider to take part.


Don't just take our word for it ...


"The Extreme lived up to its name in all senses of the word - extreme beauty, extreme challenge, and extreme fun. Day 1 through Borana offered a fantastic mix of steep climbs, epic views, thrilling descents, and plenty of KMs of moderate terrain for taking in the scenery and wildlife. Day 2 provides a bit less challenge, but just as much fun. The descent through the forest and other zones on the slopes of Mt. Kenya is fast and beautiful, and is an interesting contrast to what you get in Day 1. Overall, a fantastic event for someone looking to challenge themselves, and to be rewarded with a great sense of accomplishment…all while contributing to a fantastic cause."


"The first day Extreme route is truly magnificent. While it seems daunting it is totally doable if you are smart and pace yourself!! I’m stupid, went out too fast and had a heck of a hard time."
