The Mill Towns Race Series

The Mill Towns Race Series, powered by Post Consumer Brands, offers chip-timed marathon, half marathon and 10K distances, all run on a flat, scenic course. The marathon is a Boston-qualifying, certified course.

Take the stress out of racing toward your next PR or running your first half marathon or marathon!

The races start and finish in Memorial Park in the Mill Town of Dundas, where you'll also park, pick up your bib and enjoy pre- and post-race festivities. We will have water stops, finish line food and fun, race bibs and finisher medals. NEW FOR 2026: an optional race shirt you can order when you register. Our looping, tree-lined course takes you along the Cannon River from Dundas to the other Mill Town, Northfield, and then back again. The 10K completes one loop, the half marathon two loops and the marathon four loops.

We don't have long lines, parking headaches or an expo to add to your schedule. We will be offering packet pick up ahead of race day for those who prefer that option. Race-day packet pickup will still be available and quick.
