The Starlit (31 km)

Brave the lake in winter at night

The Starlit will take on a 31km course. It is the most demanding of the CRYO races. The only one of its kind, this crossing allows athletes who are up to the challenge to run in winter, in the dark, on magnificent lac St-Jean. The STARRY Traverse adventure begins just before sunset. Athletes take to the lake on a groomed, marked trail interspersed with refreshment points. In the middle of lac Saint-Jean, on the endless white lake, they’ll experience a change of scenery for sure.

It represents a major challenge, forcing participants to deal with nature, in the middle of the night, and to face up to the unpredictable. This event is aimed at hardened and experienced athletes who are used to running long distances and making a significant physical effort in a winter context, since the maximum time to complete the crossing will be reduced, passage times will be much more restrictive, and weather conditions may be less clement than for the SUNNY Traverse.

Participants have a maximum of 5 h 30 to complete the crossing.

This event is aimed at riders who meet one of the following criteria:

  • Have completed an ultra trail race (over 42.2km) within the last 2 years
  • OR have completed a marathon in under 3h30
  • OR have completed the Micro-CRYO in under 1h40
  • Important asset: winter running experience (micro-CRYO, polar trail, etc.)

In all, a maximum of 40 people will have the chance to take up this major challenge next February. Once this number has been reached, a committee of experts will evaluate the candidacies of those who have registered for the STARRY Traverse. As a result, proof may be required, and some people may be redirected to the SUNNY Traverse. These decisions will be final and without appeal.

Each participant is commited to raising $1,000 in donations for the On the Tip of the Toes Foundation, which helps young cancer patients regain their well-being by offering them the chance to take part in a therapeutic adventure expedition. Please note that fundraising is mandatory. Only participants who have completed 100% of their fundraising will be able to set off on February 22.

Are you ready to brave the night, the wind, the cold, the lake?

« I see the finish line through the Ice Village, the arch and the time sign, people cheering, the hostess encouraging them to make more noise. A shiver runs down my spine; not the cold-induced kind of shiver, but that of success, of pride, the sensation of floating, the ultimate happiness of the culmination of an unparalleled effort, of having overcome adversity. I cross the line in all serenity, I capture the present moment. Cryogenized, I feel alive. »
