A challenge for everyone

The CRYO Races are a truly one-of-a-kind event during which running and fatbike enthusiasts get the opportunity to cross Lac St-Jean during winter. Cyclists basking in the rising sun or runners guided by the beam of their headlamps will find themselves in the middle of a sea of ice and will attempt to meet the physical and psychological challenge of this crossing on February 19. On mechanically groomed trails, they will be supervised and supported while experiencing this icy adventure. Three events are possible: 33 km* running event, the 13 km* Micro-CRYO race, and the Fat-Lac!, a 33 km bike crossing event.

Simultaneously, many runners will take part at this challenge from home with the Crossing to GO(33 km) or the CRYO at home, a race where they choose the distance themselves.

Whether they are participating on the lake or from home, all runners have the same objective: support the On the tip of the toes Foundation.

* We are planning routes between 32 and 34 km and between 12 and 14 km. The exact distance will be confirmed at the beginning of February, when the trails grooming will have started. In fact, it is possible that we will be forced to make some detours to avoid particular areas due to unpredictability of nature.


Since 1996, the On the Tip of the Toe Foundation has organized more than 65 therapeutic adventure expeditions for young people living with cancer. Much more than outdoor adventures, these excursions offer participants an opportunity to meet other young people who share the same realities.

The On the Tip of the Toe Foundation aims to help young people rebuild self-esteem and restore their hope in life by presenting them with challenges and helping them to meet those challenges. By participating in extraordinary expeditions to the extent of their abilities, these young people discover new horizons.



Running in the winter is not the easiest! We face the darkness, the cold, the wind that pierces our clothes, the slush and even the ice. It’s both physically and psychologically demanding, and it takes a lot of mental strength. Motivated by the courage and determination shown by young people living with cancer, runners will have to brave the elements to achieve the challenge.
