About
Shamrock 5K is a mass-participation road race held on a flat out-and-back city course suitable for runners and walkers. The event combines chip-timed racing with a St. Patrick's Day block-party vibe, live bands and a large, supportive crowd. Participants receive a race shirt and medal and can enjoy post-race refreshments and an Irish after-party.
