The Boulder Stroke & Stride enters its 25th season in 2026, and offers Boulder area athletes a fun 1-lap 750 Meter Swim, or 2-lap 1500 Meter swim in Boulder Reservoir, followed by a 5k run on the reservoir dam on 8 Thursday evenings (plus one Wednesday evening) throughout the summer.

Live timing, great post race food, beanie for 6-pack entries, and series prizes are just the beginning!
Stroke & Stride happens weekly on Thursday nights throughout the Summer from June 4th to August 6th WITH THE EXCEPTION OF Thursday June 11th. Stroke & Stride will instead be held on Wednesday June 10th
