Tyler Butterfield will look to build on his promising start to the season when he races in the Ironman North American Championships at The Woodlands, Texas, tomorrow.

In a display of tremendous sportsmanship, Butterfield sacrificed his podium finish at the Ironman 70.3 Dubai in January despite crossing the finish line in third.

The Bermuda triathlete agreed to swap positions and take fourth instead after Ruedi Wild, of Switzerland, lodged a complaint having taken a wrong turn near the finish after moving into third.

With a prize purse of $150,000 and Ironman World Championships points on offer, several top names will be in action including Matt Hanson, of the United States — the 2015 winner — and compatriot Matt Russell, who placed second last year.

Butterfield is expected to be among the contenders for a podium finish.

Competitors will begin with a 2.4 mile swim in Lake Woodlands followed by a 112 mile bike course through the scenic, rolling farmland of East Texas.

The race ends with a 26.2 mile run which takes place within The Woodlands and concludes with a spectacular finish on Waterway Avenue.
