Prove It 5k & 10k

We will be able to continue this truly unique event at the GM Milford Proving Ground in 2025 for the annual Prove It 5K and 10K! 

Think you've got the fastest 5k or 10K around? Put your money where your mouth is and come race on the test track at the World Famous GM Milford Proving Ground!  We will be running on the beautiful and technical Milford Road Course (we don't think anyone will be breaking the course record as cars fly on this course at speeds well over 100 MPH!). Prove that you are as fast as you say you are with our one-of-a-kind age and gender graded running race on this historic automobile test track.  While Trivium has many fast, flat courses to get a PR, this USATF certified course is a bit more challenging!

Think you have what it takes to complete both the 5K and 10K? Race in the Double Event and not only will you get a finishers medal, but also a double trouble commemorative item!
