Programme & Village LIGHT ON A weekend by the lake.
Saturday for the bibs, Sunday for the running, and the Village LIGHT ON in the middle of it all.
The LIGHT ON spirit.
Serious trail, without taking ourselves seriously. That's the idea.
There's a distance for you
First bib or trail regular: 17, 37 or 54 KM. And everyone meets again at the same finish aid station.
The lake, the forest, the ridges
Forests, ridges and lakeshore: the routes go where the massif is at its finest. Remember to look up between two climbs.
Everyone's in the race
Runners, volunteers, supporters by the trail: everyone is part of the adventure. And the more of us there are, the more the smiles multiply. We love that! "The trail atmosphere was well captured. Very friendly and open to everyone."Paul R. 17 KM*
Fun before the clock
We come for the kilometres and the finish line... but also to look up and get an eyeful! "The route was really lovely, varied and pretty well balanced in terms of difficulty."Benjamin B. 17 KM*
Sorted, no fuss
Markings, aid stations, marshals, bibs: it's all ready, and the good mood comes included. All you have to do is run. "Great spirit, very pleasant route, volunteers really on hand, everything was simple."Emilie R. 17 KM*
The weekend, hour by hour.
Saturday to settle in, Sunday to run. The 54 starts first, the 17 brings up the rear.

It all happens at the Village LIGHT ON.
Start, finish, final aid station, stands and refreshments: it's all in one place, in Celles-sur-Plaine.




Stands & partners
Partners and the players of the Pays des Lacs set up their stands at the Village LIGHT ON, from bib pick-up through to the podiums.
Food on site
Refreshments and food made with local produce on Sunday. For the coffee before and the drink after.
LIGHT ON Shop
The LIGHT ON shop sets up at the Village. Something to take home from the race, on top of the medal.
LIGHT ON Kids
A space for the youngest, with a bouncy castle weather permitting. The grown-ups run, the little ones bounce.
LIGHT OFF
The zone to unplug: deckchairs by the lake, before or after the race. Family and friends cheer at the finish, enjoy the lake and save a spot in the sun for those still out there.
Prize-giving
Sunday at midday, at the Village LIGHT ON: podiums, applause, and a "see you next year".
Lake Pierre-Percée.
Start and finish in Celles-sur-Plaine (Vosges, 88110), by Lake de la Plaine. Just to the north, on the Meurthe-et-Moselle side, one of the largest lakes in Lorraine and miles of forest: it's Lake Pierre-Percée that sets the tone for the routes.


The lake
One of the largest lakes in Lorraine, in Meurthe-et-Moselle, just north of the Village LIGHT ON. The routes run alongside it, above it, and everyone meets it again at the finish.
The Vosges forest
Firs, undergrowth, ridges and singletrack: you run at the heart of the massif. For the detail of the three tracks, head to the 17, 37 and 54 KM routes.
Getting there and staying over
About 1h10 from Nancy, 1h20 from Strasbourg and 1h from Épinal. Access, parking and accommodation around the lake: it's all in the practical info.
Running without leaving a trace.
We run in the Pierre-Percée massif one Sunday a year. The rest of the time it belongs to those who live here: we leave it as we found it.
Zero waste on the trails
Reusable cups at the aid stations and systematic sorting. Carrying your own eco-cup is encouraged on every route.
Respectful routes
Existing trails and non-permanent markings. Everything is taken down after the race to leave nothing behind in the massif.
Short-supply aid stations
Local, seasonal produce wherever possible, to limit the footprint and support the region's producers.
Shared travel
Carpooling encouraged between runners to reduce the impact of journeys to the lake.
All that's missing is you.
Registration is open. See you on 4 April 2027.
