We are excited to announce that the 2021 Yeti Chase 5k and 10k have received the OK from the Jefferson County Health Department and the City of Lakewood to take place on January 24th!

This 5k/10k run is brought to you by Racing Underground. Conveniently located on the scenic west side of metro Denver, Bear Creek Lake Park is known for it's diverse bird and waterfowl population as well as stunning views of the foothills.

The 5k and 10k races wander it's 2500 acres with a mostly flat 5K course, while the 10k throws in a few rolling hills.

We are also offering 5k and 10k virtual options in 2021 for those of you who aren't comfortable in a group environment or live too far away but would love an awesome Yeti Chase shirt!!!

The race has sold out weeks before race day every year, and this year our entry limit has been reduced due to COVID rules so we anticipate selling out very quickly.

Details on our COVID precautions and our 2021 event are outlined below. We hope we'll see you there on January 24th!!!


Race Changes due to COVID: The Corona virus has made it difficult to hold running races in 2020, but we have worked with the City of Lakewood and the Jefferson County Health Department to develop a plan that will allow us to safely hold the Yeti Chase 5k and 10k in January. We ask that everyone please follow these precautions so we can continue to hold events in Jefferson County during this pandemic. We need to show that races can be held responsibly or our events and all other events in the county may be cancelled. Thank you for your help!

Start & Finish Lines will be in separate locations. This will allow us to hold controlled wave starts in one area, and will prevent finishers from mingling with those who have not yet started. Click here to see the revised start/finish map

Wave Starts are required to meet state and county guidelines on group size. We will have 40 waves to choose from, with a maximum of 10 runners allowed per wave. Waves are grouped by running speed to avoid mingling on the course. Please sign up for the correct wave for your running speed. Here is a general guide to running waves:

  • 5k Group A Limited to runners who will run faster than 30 minutes. Waves start every 5 minutes between 9:05am and 9:40am.
  • 5k Group B Limited to runners who will run faster than 40 minutes. Waves start every 5 minutes between 10:00am and 10:35am.
  • 5k Group C All running and walking abilities welcome. Waves start every 5 minutes between 11:05am and 11:40am.
  • 10k Group D Limited to runners who will run faster than 1 hour. Waves start every 5 minutes between 12:20pm and 12:55pm.
  • 10k Group E Limited to runners who will take more than 45 minutes to complete the course. Waves start every 5 minutes between 1:20pm and 1:55pm.

Only the starting wave and the two following waves will be allowed near the start line. Each group will be in a separate corral. Runners must remain in their vehicles until called up. We will provide you with an FM station to listen to from your vehicle so you can hear race announcements, current race leader info, and call ups for each wave.

Results will be updated online every two minutes throughout the day! Results will not be posted on-site.

Race Parking will take place in the lots near the start finish area, just a short walk (2-3 minutes) from the start line. We ask that you arrive no earlier than 45 minutes before your start, and parking staff will direct you to parking. We will provide you with an FM station to listen to from your vehicle so you can hear race announcements, current race leader info, and the call for your wave to report to the start line.

Spectators will not be allowed at the race unless they remain in the car. Spectators in the start or finish areas will be asked to return to their cars. Our permits do not allow anyone except registered runners and race staff to be present at the event. We understand you would like your friends and family to cheer you in, but this will lead to the cancellation of all events in the county. We encourage your fans to watch for your results online (they update every 2 minutes) and congratulate you with dozens of text messages. You can celebrate with them when you get home.

Masks must be worn at all times when not racing. You will be allowed to remove your mask 30 seconds before your start and you will not be required to wear a mask while racing. You will put your mask back on as you exit the finish chute.

Post Race will not be as festive as we would like, but you will receive your race shirt, a slice of Jill's famous banana chocolate chip bread, and a cup of hot cocoa or steaming noodle cup as you exit the finish area. Awards will be distributed a week after the race. Gathering after the race will no be allowed, as we have a strict limit on group size in the finish area.

That is a summary of the major COVID precautions we are taking. Please help us in making this a safe and successful event!!!
