Please note: that as of 2022 we are offering our runners the option of either getting a Treehouse 10K tshirt (as we have done in years past) or they can make the conscious decision to donate the cost of a t-shirt to Cholsey Environtment Champions’ work making Cholsey a more green village by planting more trees. Read much more about that here 

Please make your choice when placing your order by using the drop-down menu.


Our race is now affiliated with UKA under the Trail Association (TRA) for off road races.  Permit : 3207.   The key benefit of affiliating the race is that it will now count to UKA points and rankings as published on the power of 10 website.   If you race frequently you may want to consider joining an affiliated club – that way you don’t have to pay the £2 non-affiliated runner charge, and , once registered with England Athletics, there are many other benefits.  You can read about these on the England Athletics website, as well as find a club.
