Distance: Approx. 75km on Day 1 & 60km on Day 2

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 teams.

Covering approx. 80km 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 with the Roller Coaster, 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 “Classic or Rush” is the answer? You must be a seasoned mountain bike rider to take part.

Held on Day 2, the Classic is an experience that has become synonymous with the 10to4. Starting at nearly 3000 meters, (10,000 feet), on the northern slopes of Mount Kenya, riders will descend some 60km over demanding terrain, through indigenous forest and wide open plains, abundant with wildlife, down to the Ngare Ndare Forest at 1940 meters, (6400 feet) and then onto Borana Conservancy, finishing at Borana Race Village.

The ride is not, however, all downhill, featuring some vicious climbs when the body least wants it. Estimated ride time between 2 and 6 hours depending on ability. A high level of fitness and experience is required.
