‘A real honor’: How the Boston Triathlon brought supertri — and Olympic champion triathletes — to South Boston – The Boston Globe

Yee will renew his battle with Olympic silver medalist Hayden Wilde of New Zealand, whom Yee hunted down in the final moments of the men’s individual triathlon in Paris to win gold. Boston is a bit like home turf for Yee, who has long been sponsored by Boston-based New Balance.

“I remember coming down my first time to the Lenox and staying outside the where the Boston Marathon finishes,” Yee said. “And over that week of the Boston Marathon, whilst I was here, just feeling that buzz and that energy about the area, and for me, I really kind of fell in love with this place a little bit, just the energy and how excited everyone was.

“I’m excited that we’re finally able to race here.”

The supertri League is a global race series that features some of the world’s best athletes in a unique format that sees them complete three consecutive swim-bicycle-run sequences; instead of finishing their run and heading for a postrace meal, they’ll be heading straight back into the water.

“You have to think about so many different elements to the race,” Spivey said. “How you’re going to set your bike in transition, what gear you’re going to be in, if you’re going to rack your bike forwards or backwards, how many running shoes you’re going to have … It’s like all these little intricacies that you know you have to think about.”

The supertri race will serve as the closing act Sunday afternoon. The weekend starts with the kids race Saturday morning before the Olympic-distance triathlon — a 1.5-kilometer (0.93-mile) swim, a 35-kilometer (21.75-mile) bike ride, and a 10-kilometer (6.2-mile) run — at 7 a.m. Sunday. That will be followed at 8:40 a.m. by the sprint-distance race, with each leg exactly half the distance of its Olympic-distance counterpart.

Athletes will complete the swim in the harbor at Carson Beach, bike up and down Day Boulevard through Pleasure Bay, and run through Moakley Park before finishing back at the beach.

Then Sunday morning’s competitors will be able to relax with a drink and a bite to eat and watch some of the best triathletes in the world go head-to-head at 12:30 p.m.

“All of my athletes will be off the course, done and dusted, medals around their neck, beer in their hand, slice of pizza, feeling the glow of their own race,” race director Michael O’Neil said. “And then, boom, 12:30 hits, this just incredible spectator event with the world’s fastest athletes fresh off of Paris.”

“It’s really cool,” said Yee. “Triathlon’s always been a community-based sport; we’ve always focused on including everyone, no matter what level you are. People will be able to race their own race, have their own ambitions, their own goals, and then also be able to kind of appreciate what we’re doing as well.

“And from that point of view, hopefully we’ll be able to inspire some of the younger generation that have come and potentially tried the sport for the first time.”

O’Neil, once an agent in the sport before moving full-time into ownership and operation, had a longstanding connection with multiple-time triathlon world champion Chris McCormick, one of supertri’s founders.

The Boston Triathlon wasn’t quite ready for that sort of venture yet, but bringing supertri to Boston seemed like a matter of when, not if.

“It was a little early in their development, and it was also an interesting growth period for the Boston Triathlon, and I felt like it would not have been good timing to bring it to Boston then,” O’Neil explained. “We’re at a place now where this would be a good fit for us.”

That didn’t mean it was an easy undertaking to add a top-level pro race to an event that O’Neil said was already “an eight-ring circus.” With a few dozen permits required, swim clinics, media, and road closures already to account for, O’Neil and co-director Will Thomas had to figure out how to stage supertri, too.

It helped that they caught some natural breaks. The looped nature of the course made the unusual transition from the run back to the swim possible. The road closures for the race meant they already had two large parking lots either side of the McCormack Bath House at Carson Beach at their disposal to add another ring to the circus, as O’Neil and Thomas coordinated operations with their supertri counterparts in Europe.

As it turns out, from thousands of miles away, they were already on the same page.

“So we laid this out, and we had our first call with their ops guys and they had the whole thing mapped out just like we did, just from looking on Google Earth,” O’Neil said with a laugh. “And when we rolled [our plans] out, they started laughing, and they’re like, ‘This is going to be great.’ ”

So before supertri heads to Chicago, London, the south of France, and Saudi Arabia, it’ll start in South Boston.

“It’s a real honor,” O’Neil said. “There’s only five of these in the world, only two in the US, and this is the first time they’ve ever staged a race at an event that they don’t own. I think it’s a real testament to Boston being just a legendary sports town.”
