Track-ish: Mia Sirois' Journey From Broken Ankle To Team USA

Track-ish, presented by Brooks and hosted by Joshua Potts, is back on MileSplit to showcase the personalities of our best high school track and field athletes. In every show, Joshua Potts delves into what makes these athletes great, allowing them space to be themselves on the national stage.

Fresh off one of the biggest months of her career, Mia Sirois of Barrington High School (IL) joins the show after earning a spot on Team USA for the World Athletics U20 Championships. In the past month, Sirois broke the Illinois state record in the 3200m, finished runner-up in the Brooks PR 2 Mile, won the USATF U20 Championships 5000m, and ran a new mile personal record of 4:45.26 at the New Balance Outdoor Nationals. Now she's preparing to represent Team USA for the first time at the World U20 Championships, August 5-9, in Oregon.
