The Treehouse 5k and 10k is a mixed terrain course set in the beautiful South Oxfordshire countryside. The event is chip-timed and all entrants receive a t-shirt, medal and goody bag. In addition there is a children’s Fun Run where children can run as many 1k loops as they like. There are refreshments and bacon butties available afterwards, and sports massages. We have been called “the friendliest race around”.
