Tyler Butterfield, the Bermuda triathlete, has struck up a new sponsorship deal with running shoe brand On.

Co-­founded by fellow endurance athlete Olivier Bernhard, On provides runners with innovative footwear designed to maximise both comfort and speed — critical elements for any triathlete.

“I’m thrilled to be a part of the On running family with so many other world-class athletes and with a team behind the brand that understands an athlete’s needs,” Butterfield said.

“The shoes are truly visionary, pushing the boundaries of running technology to help me run fast while in good form.”

Butterfield, a one-time professional cyclist, has worked hard to prove his equal running talent at triathlon venues around the world.

His performances last year showcased his running speed and skill, most notably with a 2hr 48min personal best Ironman marathon at the South American Ironman Championship in Brazil.

Butterfield also proved himself a fleet-footed opponent against the best long-­course triathletes at the Ironman World Championship in Kailua-Kona, Hawaii, running from ninth position off the bike to finish fifth in an overall time of 8hr 23min 09sec.

The finish was his best ever and cemented the Bermudian’s place among the elite of the sport.

This year Butterfield will again gear his race schedule toward the Hawaii Ironman in Kona, with numerous half iron-distance races scheduled throughout the season.

“I really enjoy racing frequently and I’ve found that it suits me to keep a busy race calendar,” Butterfield said.
