The RunDenver Series promises a fun time through the winter months, motivating you to stay, or get, active.
The Series events have been staples in the Colorado running community for over three decades and are proudly produced by HAL Sports! HEALTHY ACTIVE LIVING!
We invite you to join us for a ton of fun, great community, fun, sweet swag, fun, epic medals, fun, playful mascots, and did we mention fun?!
Don't worry, if you can't make an event, you can switch to virtual for that event and still collect the sweet swag and epic medal, and even earn points toward the series competition!
Those that register for the full 5-event Series will receive a special swag item - this season's series swag will be an awesome 1/4 zip fleece!!
If you aren't ready to commit to the entire series, you can test the waters by registering for any/all of the events individually - you will still get that event's swag item and that event's finisher medal!

Series Competition
Here are at HAL Sports we are a competitive crew (and we know we are not alone) so the events are not only competitive on an individual event basis but you can earn point for our series competition!
Yep, you heard that right, while we are all about fun and welcome all ages, and abilities, we know that many of you have a competitive mindset (we are talking to you, the one on the treadmill "racing" the person next you) so why not a little friendly competition to carry you through the series!
You'll earn points at each event you complete, those points will accumulate throughout the series. (If you switch to completing an event virtually, you will be eligible for 80% of your points earned for that event.) At the end of the series we will award series winners based on overall points, and top achievers in each age group!
Switch to virtual
If you are registered and need to switch an event to virtual, please do so here (link will be updated closer to the first event). You will have the option to pick up your items at a later date or to pay a small fee to have your items mailed to you. You will receive instructions event week regarding how to post your virtual results - you will have 1 week to complete the distance and report your results.
*If you are signed up for the Virtual Series - your event swag items and medals will be mailed to you.
