Lace up for Boulder’s Thanksgiving Day 5K at Flatiron Park, a community tradition that brings family and friends together to celebrate what we’re grateful for. Alongside the main race, there’s a Kids 1K Fun Run, and the event gives back by donating proceeds to Boulder’s Harvest of Hope Pantry. It’s a feel-good way to start the holiday, whether you’re running, walking, or cheering from the sidelines.
