The Yukon River Quest is an annual marathon paddling race. It is the world's longest annual canoe and kayak race. The Yukon River Quest's stated mission is, "To challenge paddlers in a world-class wilderness event – a race to the midnight sun." The race takes place in late June / early July.
The Yukon River Quest was created in 1999 by canoeists in Whitehorse who thought it would be fun to host a canoe marathon event. It has evolved into a world-class, international event. It is hosted by the Yukon River Marathon Paddlers Association.
The race is 715 km on the Yukon River from Whitehorse to Dawson City. There are six checkpoints along the route including two mandatory stops. Teams must spend 7 hours in Carmacks and 3 hours in Coffee Creek.
The race must be completed in less than 85 hours. Basic survival equipment is required. A SPOT device must be tracking each team at all times. The official race rules are updated annually.
The record for the course was set by a men's voyageur canoe team in 2008. Team Kisseynew won in 39 hours 32 minutes and 43 seconds.
