About Brainy Day Trail Run

Event History: The First 15 Years

The Brainy Day 5K was created in 2007 when Brainy Day founder, Veronica Constantine, had her own hydrocephalus diagnosis and decided to raise money in an effort to help those also affected by this affliction. The mission was to not only help families, but also create research grants for medical professionals looking to end hydrocephalus.

In 2015, after donating nearly $75,000 to local organizations that shared the similar mission, the Brainy Day Fund was established. This helped Brainy Day gain even more awareness and the event grew over the next few years.

Brainy Day Today

In February of 2022, the Brainy Day Trail Run became part of Tris4Health‘s family of events, which will continue the mission that started all those years ago. Now hosted at Mosquito Creek Trails, the event offers 5K, 10K and 10 Mile distances plus a 1/2 mile fun run for all level of runners.

Brainy Day Trail Run Courses

We have distances for all! Enjoy our 5k, 10k or 10 mile courses plus our new half mile fun run, perfect for kids and families. Courses will run clockwise from the trail head. There are 2 aid stations total at the venue.

*Please note that our 5k and 10k courses are approximate due to the nature of the venue trails.

The Pediatric Hydrocephalus Foundation of Michigan

What about The Brainy Day Fund?

The Brainy Day Fund has been the recipient of the proceeds generated by the event from its inception in 2015. Beginning in 2022, on the recommendation of Brainy Day’s founder, Veronica Constantine, we are donating a portion of every race entry to the Pediatric Hydrocephalus Foundation of Michigan. PHF of MI is the primary beneficiary of the trail run.

Who is the Pediatric Hydrocephalus Foundation?

The mission of the Pediatric Hydrocephalus Foundation is to educate the community by raising the level of awareness about this brain condition. The PHF will also provide support to the families, friends and children who are diagnosed with Hydrocephalus.

The PHF will raise money for and work with the medical community in searching for a cure and additional treatment options for those with Hydrocephalus. The PHF, Inc. is a non-profit 501 (c) (3) charitable organization and as such, all contributions are tax deductible to the extent allowed by law.

A great cause and a fun run through Mosquito Creek trails. I’d ridden mountain bikes there before but always good to see things from a different perspective.
