Course Nature du Téléthon de Fourqueux

The race carries the Téléthon name, the French charity telethon held every December. The Association Sportive de Fourqueux runs the event under that banner, and its HelloAsso page is where entries and any accompanying donations are collected, so check there for how the fundraising side of the day works.

The 15 km nature course suits runners who already have a few months of regular running behind them and are happy to be out for well over an hour on uneven ground. The shorter course of about 7.5 km is the friendlier option for newer runners, for juniors running with permission, and for anyone treating the morning as a social outing rather than a race.

This is a course nature, a French term for an off-road race, so expect a mix of woodland tracks, field edges and small paths rather than an asphalt city route. After wet December weather some sections can be muddy and slippery, which makes grippy trail shoes a sensible choice.

Mareil-Marly sits in the Yvelines just west of Paris and is normally reached by car or by train to Saint-Germain-en-Laye followed by a short bus or bike ride. Details of parking and any local restrictions for the morning are worth confirming with the organiser before you travel, since village streets fill quickly on event days.

Whether on-the-day entries are taken depends on the association and on how full the field is, and the listing here does not confirm it. Entering in advance through the HelloAsso page avoids the risk of travelling to Mareil-Marly and finding the field closed.
