Chilly Willy 5K/10K/Half Marathon - Las Vegas

Bundle up and get ready to race! The Chilly Willy 5K/10K/Half Marathon is the perfect way to kick off the new year with some frosty fun and a whole lot of miles. Whether you’re tackling the 5K, digging deep for the 10K, or braving the full Half Marathon, this winter-themed event brings runners together for a crisp, refreshing challenge that celebrates the season.

Every participant will earn a finisher medal, a well-deserved reward for braving the chill and crossing that finish line. We’ll also be presenting overall and age-group awards for each distance in the usual 5-year categories starting at 10 & under, giving runners of all ages a chance to shine.

We'll be starting at 9:00 am at Bill Briare Park and heading West.

It's wrapped in cool winter vibes, complete with themed swag, an energetic race atmosphere, and a finish-line experience that makes every shiver worth it. The event is designed for everyone—from first-time 5K walkers to seasoned half-marathoners looking to start the year strong.

Layer up, lace up, and come chill with us at the Chilly Willy 5K/10K/Half Marathon… where the air is cold, but the race-day excitement is always red-hot!
