Sara Hall, will be shooting for the women’s treadmill half marathon record on June 6 in Chaski Challenge

Inspired by the success of last month’s Quarantine Backyard Ultra, a handful of elite runners will attempt to break treadmill world records across five distances next week. Sara Hall, the fastest American female marathoner of 2019, is the headliner, and will be shooting for the women’s treadmill half marathon record of 1:20:43 (Hall’s pb is 1:08:58).

The event, which will be held on Saturday, June 6, and is known as the Chaski Challenge, is the brainchild of Tyler Andrews, a 2:15 marathoner who ran a world best of 2:46:06 for 50,000 meters on the track in 2018 (LRC recorded a podcast with him shortly before that race).

Before the coronavirus pandemic hit, Andrews had planned to spend the spring training with Jim Walmsley in Flagstaff as the two men prepared to race the famed Comrades Marathon in South Africa. Instead, Andrews is now based at his parents’ house in Concord, Mass., but is still training hard and wanted to create an opportunity to allow himself and others to demonstrate their fitness.

“A lot of people are really fit out there right now and have nothing to do with it,” Andrews says. “So we wanted to do that. And then just create a really compelling, fun, conversation-provoking event that people can watch on a Saturday night and have fun with.”

Similar to the Quarantine Backyard Ultra, the Chaski Challenge will feature a free live online broadcast and tracking of the record attempts around the country with cameras aimed at each elite runner’s treadmill. 2016 Olympian Marielle Hall and ultrarunner Kris Brown (13th at 2019 Western States 100) will serve as commentators.

“Chaski Endurance Collective, which is my coaching collective, we have a bunch of different athletes from different areas on staff and we were kind of just bouncing around ideas and talking about what could we do that’s kind of building off what Quarantine Backyard Ultra did really well, because that event just absolutely crushed it,” Andrews says.

Andrews also felt the inclusive nature of the Quarantine Backyard Ultra — anyone could sign up and compete — was one of the keys to its success, and to that end, the Chaski Challenge will feature free-to-enter 5k and 50k races, which anyone can sign up for and complete during a 24-hour window beginning on June 5 at 4 p.m. ET (there is an optional donation to Feeding America’s COVID-19 relief efforts).

At 6 p.m. ET on June 6, the broadcast will begin with the men’s 50k, which features Andrews, 2014 world 100k champ Max King, and Quarantine Backyard Ultra champion Mike Wardian (2:54 50k pb). Midway through that race, the men’s half marathon (featuring 61:51 man John Raneri) and the women’s half marathon (featuring Hall and 2:27 marathoner Renee Metivier) will begin. Mario Mendoza will also be attempting to break the 50-mile record; that attempt will begin prior to the broadcast.
