What is the winter crossing of Lac St-Jean on the Double Challenge of the Two Marios?

Each participant registered for a crossing will travel the 32 km separating the 2 shores of Lac St-Jean. You will leave from the reception at Pointe-Taillon Park to go to the Village sur glaces of Roberval. Your journey is fully supported by the On the Tip of the Toes Foundation. You must therefore provide your personal material and carry out your personal campaign, the Foundation team will take care of the rest. During your crossing, you will be accommodated in an expedition tent, you will feast on delicious meals and will be able to benefit from a loan of certain specialized equipment necessary to fully appreciate your winter camping experience. More details on how to prepare for your adventure will be communicated to you once you have registered.

Each day, expect to cover an approximate distance of 10 to 12 kilometres, on your own skis or snowshoes. Throughout the course, you will pull your personal equipment behind you. Of course, you will experience a physical challenge during these 3 days, but it is above all a second, more interior challenge that will leave its mark on you. The secondary goal of the Double Challenge of the Two Marios, which is as important as it is instructive, is to allow participants to have a truly unique outdoor experience, reserved for those ready to surpass themselves and willing to compete with themselves during a 3-day expedition in genuine arctic territory.
