Get ready to kick off this Thanksgiving with a dash of community spirit at the Alpine Bank Boulder Thanksgiving Day 5K and Kids 1K Fun Run! It's more than just a run; it's a celebration of gratitude, giving back, and gobble-worthy fun at Flatiron Park. Each stride you take helps the less fortunate, with race proceeds benefiting Boulder's Harvest of Hope Pantry. Amp up the kindness by bringing your canned goods on race day or raise funds per mile — with rewarding prizes for top fundraisers, including coveted plaques and generous donations to the pantry in your team's name. Don't forget, signing up before November 6th snags you a free T-shirt, and while baby strollers are in, furry four-legged friends will have to cheer from the sidelines. Let's trot together for good causes and great memories!
