Support the Brainy Day Fund

 Sign up for the 2019 Brainy Day Trail Run
August 17, 2019

Help us celebrate The 13th Annual Brainy Day 5K & 10K Trail Run.  Run the race that has the second-best race announcer in West Michigan and the third-best benefiting non-profit, – according to the 2018 Stellafly FLY Awards

This great local event supports those who are affected by a neurological condition called hydrocephalus. All proceeds from this race are donated to The Brainy Day Fund. The money raised by the Fund is used to directly support families that are dealing with this condition in their daily lives. Whether we're sponsoring a child to go to a special summer camp just for kids with hydrocephalus or providing research grants, our goal is to make as much of an impact as possible.
The 5K course includes sandy areas, hills, wooded areas, pond and beautiful Nunica farmland. It is a great first trail run for beginners and a moderately fast course for trail lovers of all skill levels.
The 10K course is challenging, but it offers a sense of accomplishment that will empower you and leave you feeling awesome. Much hillier than the 5k, the course is breathtakingly stunning in more than one way. The 10K course is perfect for adventure-seeking, nature-loving trail runners.

Join us for an EPIC After-Party

We had some incredible feedback from our After-Party in 2018, so much so that we're bringing it back in 2019. This race is not just about showing up and running, this is a family-friendly event. The after-party is open to runners and their family & friends. We're bringing back the FRESH FRUIT from Mellema Farms, PIZZA from Papa Murphy's, FROZEN YOGURT from Menchie's, and for Anyone who is 21+, adult beverages. 

New Finisher Medals

Coming back again in 2019 is our custom Finisher Medals. Big thanks to Maxwell Medals for this year's amazing design on both the medal and ribbons. Unique ribbon designs for 5K & 10K; if you finish both races you will receive two medals!

Award Breakdown

  • The Overall Top 3 Male & Female runners in both the 5K and 10K races will receive cash prizes & a commemorative stein
  • Age group winners will receive amazing farm-fresh vegetables from Mellema Farms, one of our long-time sponsors 

Same Great Shirt Styles – New Shirt Design

Thanks to the great work from Drivn Threads, the race's 2019 shirt design takes elements from our new logo and gives it a fresh feel. We want you to proudly wear your Brainy Day gear for years to come (keep in mind, shirts are not included with your registration fee). If you feel like you have too many race shirts in your closet, you can simply register for the race.  Drivn is behind the race logos of the Grand Rapids Triathlon, MiTi and Grand Rapids Beer Mile. 

#NoMoreBS National Campaign Support

In 2018, we offered a shirt style that promoted the "No More Brain Surgeries" National Campaign, a.k.a. #NoMoreBS. Some folks thought that was too provocative for their tastes – which is totally understandable. This year, we're doing the campaign again, but we've changed the design slightly to place more emphasis on "No More Brain Surgeries" AND we've added a fundraising component. The "No More Brain Surgeries" version of the long-sleeved shirt will be sold at a premium price of $25; we'll be donating ALL PROCEEDS from this shirt design to support the Hydrocephalus Association and the #NoMoreBS campaign.  


Shirts not included with registration

We're a lot different than a lot of races, we don't include shirts as part of your registration fee for two reasons: we try to donate as much as your runner fee as possible to the Brainy Day Fund AND many folks are selective on the type of shirt they'd like from a race. Thanks to our local shirt vendor, we're able to provide lots of options for race gear and we sell them at a price as close to cost as possible. You can order shirts as part of your registration or on race day (prices are adjusted on race day).

Remembering your Brainy Day moments

We were so happy to have Team Stellafly join us last year – athletes & photographers – that we're partnering with them again in 2019. StellaFly will be out on the course, as well as at race headquarters, capturing some of your favorite moments of the day. We're also working with 40 Visuals again to develop a new backdrop for your best post-race medal pictures. Make sure you plan to stick around after the race to enjoy all of the festivities.
