Run Pure + Simple is our no-bells series of races. These events offer great atmospheres with nothing extra, and are FREE to Run Waterloo members.

This race is a 2k out and back, and uses the entire flat unpaved section of the Mill Run Trail between Speedsville Road and Beaverdale Road, running under King's Highway 401. Parking is available at Riverside Park with a short walk; there is an at-grade crossing at Speedsville Road to get to the race start.

No swag, no food, no awards, just a certified and chiptimed 4k to get your spring into gear. Although, the race just might be 4.01k, so pace yourself accordingly for the extra .01k.
