Yak Attack is the highest mountain bike race in the world, covering over 400km and altitudes of 12,000m. If you’re not super fit, don’t even bother considering it.

The weather flips between humid jungle territory at 30°c below dipping well below -15°c as you climb further up the mountain. Along with that you’ll get everything from muddy bogs to wade through, seriously steep singletracks, rickety suspensions bridges and snow!

At 5,416m above sea level, the oxygen levels are 50 per cent less than below, so there’s more to overcome than just treacherous trails.

It costs £2,295 per person. Get yourself better acquainted with the event here.
