Stand-up paddle-boarders are taking part in the race for the very first time, after rules were made to include stand-up paddle boards.
The 18th annual Yukon River Quest is underway, as close to 240 competitors hit the fast flowing Yukon River in Whitehorse.
Tony Bain of Wales, is one of 12 stand-up paddle boarders in this year's race and says the support he's received has been surprising.
"We're feeling pretty special actually." said Bain.
"We've been around town for the last few days and everybody that finds out we're paddle-boarders are like 'Oh wow, you're a paddle-boarder!' So that's cool. The town's really behind us and I think it's gonna be really good for the town and (for) tourism, having SUP enter the event."
Bain didn't know if he would even be competing as of 8:30 this morning as his paddle-board and equipment were still in transit from the United Kingdom.
The first checkpoint of the 715 kilometre race to Dawson will be Policeman's point.
