Help us celebrate The 12th Annual Brainy Day 5K & 10K Trail Run, August 11, 2018.  This great local event supports those who suffer from a neurological condition called hydrocephalus. All proceeds are donated to The Brainy Day Fund. 
The 2018 Brainy Day Trail Run is brought to you by Odd Side Ales, Outfront Medai, and WGHN 92.1.
The 5K course includes sandy areas, some hills, beautiful wooded areas, a pond and amazing 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.

**New in 2018** Brainy Day After-Party – presented by Odd Side Ales

We're very happy to announce that in 2018 we'll be adding a family-friendly post-race party to the lineup of events. We're still working out all of the details, but there will be beverages and food for everyone. It is open to runners and their family & friends. Anyone who is 21+ will have the opportunity to get a free beer courtesy of our Title Sponsor, Odd Side Ales in Grand Haven. 

**New in 2018** Finisher Medals

If you put the time in to race, we feel your efforts should be rewarded. If you run both the 5K & 10K you will receive both finisher medals. Medals are limited to the first 185 5K finishers and 115 10K finishers.

**New in 2018** New Logo & Reflective Printing

Thanks to the great work from Drivn Threads, the race has a brand new logo. Drivn is behind the race logos of the Grand Rapids Triathlon, MiTi and Grand Rapids Beer Mile. Even better, our race shirts will incorporate reflective priting. We're really excited to see these shirts on the trails.

Shirts available (not included with registration)

Every year, our fundraising objective is to donate as much of your runner fee as possible to The Brainy Day Fund. By taking out the cost of shirts, it allowed us to keep the entry fees low at the same time maximizing your overall donation to the Fund. We've also expanded our apparel options, providing a short and long-sleeve shirt, as well as a lightweight beach hoodie – perfect for summers on the lakeshore.

**You will be able to order shirts on race day. Additional fees will be added to the cost to accommodate drop shipping.



  • Finishers from the 5K & 10K will receive a custom finishers' medal. 
  • The Overall Top 3 Male & Female runners in both the 5K and 10K races will receive cash prizes, a unique medal & a commemorative Brainy Day Trail Run stein.
  • Age group winners will receive amazing farm-fresh vegetables from Mellema Farms, one of our long-time sponsors.
