Flatwater Runs
Flatwater is proud to be an Official Charity Partner of select marathon events around the world, connecting runners to our mission of providing access to mental health therapy for individuals and families impacted by cancer.
Endurance events are one of the ways Flatwater raises critical funds and spreads awareness for our mission: providing access to mental health therapy for individuals and families impacted by cancer.
As an Official Charity Partner of select races, Flatwater receives a limited number of charity entries. Team Flatwater runners commit to fundraising before race day, turning each mile into greater access to care.
100% of the funds raised directly support Flatwater’s mission, helping remove the financial barrier to therapy for people navigating cancer at any stage in the journey.
When you run with Team Flatwater, every mile helps someone impacted by cancer access the mental health care they deserve.

the impact of fundraising
100% of proceeds go directly to Flatwater’s mission
A cancer diagnosis impacts far more than the person diagnosed. Flatwater connects individuals and families in the Central Texas community to licensed mental health therapists, providing up to 40 therapy sessions at no cost for those navigating cancer at any stage of the journey.
Since 2010, Flatwater has funded more than 78,000 mental health therapy sessions.
