Tyler Butterfield will race tomorrow in the Mont-Tremblant 70.3 triathlon in Quebec, with 35 qualifying spots for the World Championships in Hawaii up for grabs.

A few thousand triathletes will take over Mont-Tremblant village tomorrow to tackle the challenging course.

Both of last year’s winners, Jesse Thomas and Meredith Kessler, are back and aiming to defend their titles, but they will be challenged by some strong competition.

On the men’s side, Lionel Sanders, who moved from last to fourth place on this course during the ride and run at the Ironman 70.3 World Championships in 2014 is a threat.

Sanders will also be joined by Cody Beals, who is fresh off his win at Ironman 70.3 Eagleman last weekend, and Taylor Reid, the ITU speedster-turned long course threat. Beals is a fast-rising professional who consistently posts among the top bike splits in all of his races.

Americans Richie Cunningham and Andrew Yoder as well as Butterfield are also certain to push the pace tomorrow.
