About The Women's Run Series

Making Your Run Meaningful and Welcoming.

Everyone deserves a positive and supportive running environment. The Women's Run Series eliminates any feeling of intimidation or inadequacy that many race environments create. Instead, we offer a supportive space, that when you leave you will feel empowered and accomplished. It's a safe place to run, or walk, that isn't about winning, it's about coming together as women to finish and celebrate.

Your wings already exist.  All you have to do is FLY!

Butterfly Dash Information 

This event is for our younger participants and for those who want to run with mom!  It is an untimed run and is approximately a half mile in distance.  A parent wishing to run with their child does not need to register in order to do so. 

All Butterfly Dash participants will receive the following:

  • Custom Dri Fit Short Sleeve Event Shirt
  • Custom Finisher's Medal - just like mom!
  • Custom Event Bib
  • Drawstring Bag
  • Mylar Butterfly Balloon at the Finish Line!

Coming Soon!  Our Frequent Flyer program!  Participate in at least 2 of our series events and earn extra rewards!

Charity Partner

We are proud to be partnered with Girls on the Run of Tucson for this event!  

Girls on the Run is a transformational physical activity based positive youth development program for girls in 3rd-8th grade. They teach life skills through dynamic interactive lessons and running games. The program culminates with the girls being physically and emotionally prepared to complete a celebratory 5k running event. The goal of the program is to unleash confidence through accomplishment while establishing a lifetime appreciation of health and fitness. 

At Girls on the Run they envision a world where all girls know and activate their limitless potential.  And more than that, they are working to make that vision a reality - one where girls can navigate their lives with confidence and joy.  One girl at a time, they've changed a million lives.  With your support, one girl at a time, they will change a million more.


Thank you to our Sponsors!
