About this race
Brian Diemer 5k is celebrating their 36th year! We are happy to return to in 2026 to celebrate our 36th year, so come run again with the three-time Olympian, Brian Diemer on our flat, fast 5k course. We are bringing back 6 live bands on our course, the kids' runs, handcycle, My Team Triumph, and a large prize money purse. Per usual - if you beat Brian, you win a donut!
New this year is the Special Olympics Sprint for Inclusion! This 100 meter dash is open to everyone and takes place right before the start of the 5K. Great way to warm up while raising support for our area's Special Olympics organization.
Check out the 2025 pictures from Stellafly and Jamie Geysbeek Photography.
