The 5th edition of the Trail de la Ligne Rouge (Red Line Trail) is scheduled for Sunday, May 17, 2026, in the historic commune of Thiescourt, Oise (60), France. This event offers a profound athletic experience, leading runners along the "trace des poilus"—the historical front lines marked by the Great War. The course follows a developing Grand Randonnée de Pays (GRP) route, specifically designed to connect the communes of the 14-18 front through a natural, obstacle-free trail experience.
| Race Distance | Vertical Gain (D+) | Format Options | Participant Cap |
|---|---|---|---|
| 101 km (Ultra) | 1360 m | Solo, Relay (2-8 runners), Challenge | 100 (Solo) |
| 43 km | 920 m | Individual | 150 |
| 21 km | 440 m | Individual | 250 |
| 10 km | 190 m | Individual | 250 |
The terrain is famously described as "gras" (heavy or muddy), echoing the conditions of the trenches once located in these plains. The 101 km route is the centerpiece of the weekend, allowing for solo efforts or collaborative team participation via relay. This ultra-distance is also available as an "Intervillage/Enterprise Challenge," fostering camaraderie among local communities and corporate teams.
Logistical amenities provided for all athletes include:
The event operates with strict age requirements for safety, ranging from a minimum age of 16 for the 10 km race to 20 years for the more grueling ultra-distances. This trail serves as a precursor to the upcoming permanent GRP, which will soon allow hikers and runners to follow the historical "Red Line" throughout the entire year.
