Would you like the Yak Attack experience
but without the pressure of our race format?

Welcome to Yak Attack


The Yak Attack series of mountain bike races can’t be classified as XC, Marathon or Enduro; they are in a league of their own.

Rather than races, they are akin to battles, a battle between mountain biker and Mother Nature.

Each event has its own unique set of challenges and obstacles, supplied by nature and tweaked by The Yak Attack, from the altitude of Nepal, to the heat of Sri Lanka and the ferocious winds of Patagonia.

The Yak Attack races definitely aren’t for the armchair rider, but they also aren’t just for the elite. Physical fitness, a mental toughness and the tenacity to endure the extreme, are attributes that will get you to the finish line.

If this is you, then choose your war and let battle commence.

World Challenge Series Sponsors



Due to the success of Yak Attack over the years, we have been able to make some small contributions to the Nepalese MTB community through our Yak Attack Foundation. In 2013, we financed some of the top riders to the Asian MTB Games in China, to the prestigious Langkawi event in Malaysia, and supported Ajay Pandit Chhetri, the current Yak Attack Champion, for a season of racing in the UK. This year, we will be financing the top 3 riders to the World Cup in South Africa. This exposure to more competitive international fields has already had an impact on the team’s level of performance and professionalism which, in turn, has helped to raise the profile of the sport in Nepal and the potential economic, health and well-being benefits for young people working, or striving to work, in the country’s fast growing mountain biking industry.

We will also be offering free entry for five local riders in the 2015 Yak Attack, as well as already taking the current male and female Nepali Yak Attack champs (Ajay Pandit Chhetri and Laxmi Magar) to Sri Lanka in November to compete in Rumble in the Jungle.

Another cause close to our hearts is the welfare of animals in Nepal. Therefore, we are also strong supporters of the Himalayan Mutt Foundation, a great association that is working towards vaccinating and neutering dogs in the Annapurna region and we will be providing ongoing support to their cause in the future.

It is thanks to all previous Yak Attack entrants that we are able to help support these worthwhile projects and, as our race series grows, we hope our support can be even greater in the host countries of our events . If you would like to make a donation to the Yak Attack Foundation or maybe raise funds through a sponsored event (such as YA2015!) then please contact for a sponsor form.
