(Posted 31st January 2023)




Registration for the Tropic Air 10to4 Mountain Bike Challenge closes at midnight tonight!

With well over 300 entries already, we’re almost at capacity for all races. This is fantastic news for us, but if you don’t submit your entry today it will be bad luck for you as we won’t be accepting any more after midnight. So don’t put it off any longer ….


Register now!


If you’ve already registered – THANK YOU!

But please remember that your place is not secure until you have paid in full – see this link for details of ways to pay if you haven’t already done so.  And don’t forget to complete your waiver and medical form online and avoid the queues at on-site registration.


The Tropic Air 10to4 event now offers five different mountain bike races, including separate classes for e-bikes, as well as the Mini10to4 on a fabulous course designed with the help of the Safari Simbaz, new for 2023! So if you’re up for the ultimate adrenaline rush or want a more family-friendly challenge, there’s a race for you.
Or if you’d rather experience the mountain from the back of a horse, the Rose Dyer Adventure Ride is just what you’re looking for. Find out more, or register now.
BRV is at the heart of the 10to4 weekend, with a beautiful campsite amongst the trees and all your favourite food and drink outlets and trade stands. New for 2023 and thanks to a generous donation from Braeburn School, we’re adding a whole new kids’ area too, so our younger visitors will have plenty to do while their grown ups are racing around on the mountain. This year, there’s also the opportunity to camp in style, with tents4events private camping and facilities.
The Tropic Air 10to4 Mountain Bike Challenge and Borana Conservancy’s Riding Wild Adventure Ride raise vital funding for the Mount Kenya Trust. This supports work to protect the wildlife, forests and water resources of Africa’s second highest mountain, as well as delivering education and health programs for local people.
Of course, we wouldn’t be able to host such a fabulous event without the amazing generosity of our sponsors and partners, many of whom support us year after year and are as invested in the mountain as we are!
