Red Rocks Amphitheatre will serve as the background for what could be the sweatiest “girls day out,” ever.

The Gildan Esprit de She has expanded to Colorado with 5K and 10K races, yoga and bonuses like manicures and wine. Yes, wine. The event also features a concert by country music star Jana Kramer.

The event happens on Oct. 22 with fitness events during the day and the concert in the evening. The event bills itself as the first female-focused fitness mash-up, with Esprit de She focused on women athletes competing and enjoying the organized events. Don’t worry, guys, you’re invited to join the ladies for the concert.

This is the first year the event has been held in Colorado. Proceeds benefit the local chapter of the non-profit group Girls on the Run.
