Not Your Typical Race

50% Entries Reserved For Women

Ultra-running has historically been a male-dominated sport and we are doing what we can to inspire women to participate in this fun, supportive and life-changing sport. We want to see 50% women at the start line and out on the course of the Dirty 30. WE ARE STRONGER TOGETHER.

Dirty 30 Teams Overview

This is not a relay. Each team member runs the entire 50K course. Each runner will get their individual time. Then each team receives a “Team Time” based on the 3 fastest individual finish times added together.

• Each team will fit in one of the 3 categories: women's, men's, or mixed.
  
• Each team can have as many members as you like but must have at least 3 racers.
  
• Each team must include at least 1 first-time ultra runner (Sisu).
  
• Teams are highly encouraged. Everyone should be on a team. Creating a team is a great way to make new friends and build support. This is a hard race and we all need support getting to the finish line. We are stronger together.
  
• It is easy to create a team. Just answer the "Team" question at registration with the name of your team. You can add members after you register. Members of your team will enter the same team name. Entrants can log onto their Ultra Sign Up account and add, change or remove themselves from a team.
