For her first season hosting Working, Slate’s own Shannon Palus is delving into the world of running, talking to professional athletes and people who do all manner of things to help people run.

This week, Shannon talks to Mirna Valerio, professional ultra runner, speaker and author of the book A Beautiful Work in Progress. Mirna started her journey toward becoming a professional athlete with her blog Fatgirlrunning, documenting her progress from casual runner to ultra marathoner. Mirna talks about how she champions inclusivity in the sport through her speaking engagements, partnerships with brands like REI and Skirt Sports and her Slow As F*ck Running Retreats.
