Hundreds of paddle-wielding adventurers leftWhitehorse on Wednesday to begin the 2016 Yukon River Quest, the longest annual canoe,kayak and, for the first time, stand up paddleboardingrace in the world.

• Stand up paddleboarding to debut at 2016 Yukon River Quest
• With 3 months to go, Yukon River Quest has almost-full roster

One of those is 71-year-old David Thom, who made his way from Ireland to kayak the race, saying that its length does come with some unique challenges.

"We've got to carry everything in the water, non-stop, apart from the seven hour sleepover in Carmacks," he said beforethe race. "It's pretty tough. Especially on the bum."

Numbers have swelled for this year's race: last year, there were 155 paddlers, and in 2014, 153.

The attendance boost has meant a surge in business for Scott McDougall, the owner of Whitehorse store Kanoe People.

"It's been crazy," he said. "You know, a fun crazy. They're in the store buying last minute stuff all the time, especially the last day before the race."

Stand up paddleboardingmakes debut

This year's quest alsosees a new group of adventurers takingthe waters next to canoeists and kayakers. Stand up paddleboardingwill make its Yukon River Quest debut, with 12 participants set to compete, including three locals.

"I was really lured in by the adventure," said Michelle Eshpeter, one of the Yukon participants, "and that it was the first year.

I'm anticipating everything hurting when I get to Dawson," she added,with a laugh.

Stand up paddleboardingis an experimental categoryfor this year's River Quest, and will be exempt from prize money. Organizer Jeff Brady previously said that if enough paddleboarders can finish the race before the 74-hour cutoff (not including 10 hours of mandatory layovers), it will be added as an official class for the 2017 race.

Paddleboardersarerequired to carry the same gear as canoe and kayak teams, with survival supplies in dry bags on their boards.

Stephen Wattereus is another local participant, and says that he's looking forward to learning from experienced racersduring what's anticipated to be a three-day journey. Several world-class endurance paddlers have signed up for the event, including Hawaii's Bart de Zwart, who's won the Netherlands'200-plus kilometre 11 City Tour four times.

"It's new for everyone, so it's yet to be seen whether a person can stand for three days," said Wattereus. "It's great to learn from more seasoned paddlers.

"My personal goal is to not fall in the river at the start... to complete the quest would be fantastic."

The cut off time for finishing the quest is at 11:59 PM on Saturday, July 2.
