Ultrarunners Rob Krar, Karl Hoagland and Caroline Boller will be featured in a new film titled “This Is Your Day” produced by USL.TV. The 52-minute documentary follows the three athletes in their final preparations before this year’s Western States 100, but mainly focuses on each athlete’s relationship to the sport of ultrarunning and how it affects those around them on and off the course.

“We get the title ‘This Is Your Day’ from a quote in an interview with Rob as seen in the trailer at the start of Western States last year,” says the film’s director Myles Smythe. “For me that title expands itself into the whole film’s concept of when you’re going to run a race you don’t do it on your own, it’s a team effort. So we’re really telling the story of the runner’s race from the perspective of their crew, pacers and entire support system.”

Initially the inspiration behind the film started with CEO and founder of USL.TV Mike Cloward, a self-described middle-of-the-pack ultrarunner, who had been exchanging ideas with Smythe about filming interactions between crew and ultra-racers within nature. At the same time Cloward was also motivated by his conversation with two-time (2014 and 2015) Western States champion Rob Krar about ultrarunning’s misconception as an individual sport, and telling the story of friends, family and volunteers who really make the sport possible.

“The runners and the actual venue is almost in the background, and the crew and the support system comes to the forefront. That’s the basis of the idea and I think the movie reflects that rather well,” Cloward says.

Besides Krar’s appearance in the film, Hoagland and Boller were also chosen to give the film more narrative diversity. Hoagland, a 50-year-old veteran ultrarunner who has completed more than 40 ultras, including seven Western States, was able to finish this year’s race under 24 hours. On the other end of the spectrum, Boller, a 40-year-old part-time attorney, wife and mother of two recently started running seriously in 2012—having strictly run on treadmills before hitting the trails. This year she finished her first 100-miler in 8th place for the women’s field at Western States.

Although, running 50-plus miles seems inconceivable to some people, the stories told through Krar, Hoagland and Boller are meant to transcend the film’s framework around ultrarunning.

“The message that every person in the film is saying, I can connect with on a personal level outside of my running life. I think that if someone is just wanting to watch an encouraging and inspirational film regardless of the topic, this may speak to a large number of people in that way,” Myles says.

The film premiers Aug. 19 in Flagstaff, Ariz., and it’s second showing in San Francisco on Sept. 19 includes a Q&A with all three of the starring athletes. Other showings in cities across the U.S. such as Charlotte, N.C., St. Louis, Auburn, Calif., and Lake Tahoe, Calif., are in the works and more information on future showings can be found on USL.TV’s website.
