TriaLong & TriaCourt 2026

TriaLong & TriaCourt 2026 is a weekend triathlon festival held in Bois‑le‑Roi, France, bringing together long, Olympic and family-friendly cross formats under the TriaLong & TriaCourt brand. The programme spans Saturday 12 and Sunday 13 September 2026 and features the flagship long-distance TriaLong, the Olympic-distance Triacourt and a Crosstri offering aimed at children and families.

The weekend emphasises a nature-centred experience in the Bois‑le‑Roi area with clearly signposted courses and separate start times for the main distances. TriaLong is promoted as the weekend's principal endurance challenge while Triacourt is presented as an approachable Olympic-distance option; Crosstri and youth categories provide shorter or technical formats for younger athletes.
