This year’s theme for the Annual 5K Reindeer Run and Rudolph’s DASH is Color Craze

(Ontario, California) – The Annual 5K Reindeer Run and Rudolph’s Dash Fun Run returns to Ontario on Saturday, December 13. This year’s theme, Color Craze, marks the City’s first-ever color run — a vibrant twist on a community favorite! Participants will be showered with bursts of bright, cheerful color at various points along the course, creating a one-of-a-kind holiday experience.

The City of Ontario is proud to continue its sponsorship of the Annual 5K Reindeer Run and Rudolph’s DASH Fun Run. All proceeds from the race will be donated to the Ontario Montclair Promise Scholars and the City’s Empowerment Scholarship.

Families are encouraged to sign up for the Rudolph’s Dash. It’s a shorter course where kids can run or walk, and families can participate together. Rudolph’s Dash is geared toward younger participants, families with strollers, or anyone who wants to join the race on a smaller scale.

The 5K Reindeer Run will begin after Rudolph’s Dash. This race is perfect for runners of all levels.

Participants can run or walk; families and friends can participate together. Both races begin and end in downtown Ontario. After the race, meet at Rudolph’s Roundup Area at Ontario Town Square to participate in activities and crafts.
