In 2006, Simon Carrier and Patrick Lesage biked 7500 km in 48 days from Newfoundland to British Columbia as part of the "From Sea to Sea" expedition. From there, they traded their bikes for sea kayaks and paddled 6500 km to come back to the east coast of Canada. They chose the Northern route, being inspired by the first fur trade water routes, and expecting to reach the Atlantic before winter. However, once in James Bay they realized the cold weather had won the race and they decided to paddle up the mythic Harricana River to reach their hometown, Amos (Québec).

In June 2010, Simon will start the second and last phase of this expedition, now called "From Sea to Sea, a Continuation". He will bike the 800 km separating Amos to Radisson. From there his new partner, Maxime Geoffroy - a long time kayaker, will join him with two sea kayaks. The two protagonists will paddle 1600 km through remote Québec wilderness to reach the Atlantic Ocean in Cartwright, Labrador. In complete autonomy, they will paddle up La Grande River, Robert-Bourassa Reservoir, Laforge River, and Caniapiscau Reservoir to reach Labrador. There, water will finally flow toward the Atlantic, and paddling down McFadden and Churchill Rivers will certainly be an awesome challenge. Simon and Maxime want to keep an average of 45-50 km per day, allowing themselves 5 weeks to complete the kayak section."
