Inaugural Physiology First 50k September 22

Join us for our fundraising event for our nonprofit organization focused on youth anxiety.

 We are offering a 5k (with a twist), a 10k, and “fat-ass” style 50k in which participants can run the full 50k distance or as many of the 10k out and backs as they want! 

The course starts in the parking lot of our local gym which will serve as an aid station/nonstop party during the run/post run bbq headquarters. You will run approximately 800 meters on road and the remainder of the course takes place on gorgeous and technical singletrack trails. I emphasize technical! These aren’t the White Mountains, but they aren’t groomed trails either. They are rooty, rocky and super fun to run!

“Nose Only” 5k: This unique event may be a one of a  kind in the sport! Runners must run with mouths closed (honor system in place) and breathe only through their nose for the duration of the run. This is a true test of aerobic efficiency and capacity and may find some fast, front runners eating humble pie before eating delicious bbq later in the day! Begins at 8am on September 22nd.

10k: One “out-and-back” followed by lots of time to hang out, cheer on the 50k runners and attend any number of our free mini clinics throughout the day on injury prevention, strength training for runners, breathing for endurance sports and more! Begins at 8am on September 22nd.

50k: Run the full distance or as many 10k loops as you like! The weather in Maine is GORGEOUS this time of year and the trails are so awesome that you may find it hard to stop! Begins at 9am on September 22nd.

Looking forward to seeing you for an awesome run in September!

Research + Resources


Breath and The Brain:

This study details the work of one of our partners, Dr. Jose Herrero. Dr. Herrero is studying the effects of various breathing patterns on cognition, memory retention, and anxiety.


Breath, stress and High Performance SCENARIOS

In January of 2018 our coaching team traveled to Stanford University to take part in the following experiments around fear, anxiety, and mental performance using virtual reality technologies. We share some of this experience, as well as the key lessons learned, in the Breathe to Perform seminar series.
