Kona, Nice, and…Milwaukee? This weekend, a world-class field of triathletes will descend upon Wisconsin for the fast and furious PTO U.S. Open. The race, which will feature two thrilling days of racing – one for men, and one for women – brings the best short- and long-course triathletes together to battle it out over the 100K “PTO distance” – a 2-kilometer swim, 80-kilometer bike, and 18-kilometer run. The races kick off at 4:00 p.m. local time (5:00 p.m. ET/2:00 p.m. PT) this Friday and Saturday, and will be streamed live for free on Outside Watch. Coverage will also be available on demand post-race for Outside+ members (become one today).

The PTO U.S. Open course

The short (but not too short) distance lends itself well to prime-time viewing, and the layout of the event – seven and five loops on the bike and run, respectively – will make for some fascinating race dynamics, both on the livestream and in person. Throw in the picturesque scenery of Lake Michigan’s shoreline and Milwaukee’s iconic cityscape, and you’ve got yourself quite a race.

But the pros won’t be the only show in town. With the U.S. Triathlon Age-Group Nationals taking place at the same venue on the same weekend, the PTO course will be lined with more than 7,000 triathletes in town for their own championship event. They’ll be joined by an expected 20,000 triathlon-crazed fans, lining the streets for a shot at seeing their favorite pros whiz past.

PTO U.S. Open livestream: Who to watch

There are so many big names racing the PTO U.S. Open, our triathlon analyst couldn’t fit them all in his pro preview of the men’s and women’s races. But just to give you a taste, a few of the pros you’ll see racing this weekend: reigning Olympic and 70.3 world champion Kristian Blummenfelt, Olympian and 70.3 world champion Taylor Knibb, newly-crowned Challenge Roth course record holder Magnus Ditlev, defending U.S. Open champion and PTO #1-ranked Ashleigh Gentle, and multi-hyphenate champion Jan Frodeno.

But wait! It gets better. Paula Findlay, Kat Matthews, Aaron Royle, Tamara Jewett are also racing, as are Lionel Sanders, Holly Lawrence, Ben Kanute, India Lee, Jocelyn McCauley, Tim O’Donnell, and Clement Mignon, among many others.
