Trail of the Bois des Côtes — 6th edition (2026)

The Trail du Bois des Côtes (Trail du Bois des Côtes — 6e édition) is a weekend trail running festival centred on Bailleval in the Oise, organised by the trail section of Entente Athlétique de Creil. The event returns for its 6th edition on 27–28 June 2026 and offers multiple distances through demanding forest terrain, emphasising technical singletrack and rural paths. The programme includes long and medium trail races, shorter evening trails, non-competitive hikes and dedicated children’s races, with online registration open via the event registration partner Adeorun.

The event is promoted as a UTMB Index qualifying meeting for its principal distances and features distributed aid stations and an on-site medical provision. The start/finish hub is located at Parc du château de Béthencourt (22 rue du Grand Aulnois, Bailleval), and the organising team is the trail section of Entente Athlétique de Creil in association with Entente Oise Athlétisme. Practical details such as exact start waves, full GPX maps and detailed inclusion items are published on the official site and the dedicated registration pages.
