Every upcoming 5K around Centennial, with start times, entry fees, finish-time stats from past editions, start-line maps, and the local run clubs to train with.
32 upcoming 5K races found · 1 with finish-time stats
Centennial is woven together by greenbelts - the High Line Canal, Willow Creek, Cherry Creek State Park - and that web of paths and park loops is exactly the texture you feel when you race here. Even routes that look flat on a map have the gentle climbing that Centennial's gullies and ravines quietly add to every mile.
The running community gathers around those trail corridors, and the races reflect that: a mix of themed fun runs and cause-driven events sitting alongside the occasional trail-focused event, with post-race culture that feels very much rooted in the neighborhoods rather than a downtown finish-line festival.
By the numbers
The Biggest and Longest-Running
The Centennial races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 8, 2026.
Common Questions About Running a 5K in Centennial
What does a typical 5K finisher look like at these races - will I be at the back of the pack?
Only one race - the Arapahoe Warrior 5K - has published finish results. Across that edition, the median finisher came in at 27:31 in a field of 162 runners. That is the only measured benchmark available from Centennial 5K races, so treat it as a data point from one race, not a general rule.
What is a good first race here if I am new to 5Ks?
Many races on the calendar also offer a 1 Mile option alongside the 5K, which gives a genuine on-ramp if 3.1 miles feels like a stretch right now. A good number of the themed fun runs - coffee, donuts, bagels - tend to draw mixed fields that include first-timers, which usually makes for a relaxed atmosphere at the start line.
When are most of the races scheduled - is there a season I should plan around?
Fall (September to November) is the busiest stretch, with 12 races. August is the single busiest individual month with 7 races. If your training block peaks in summer, you will still find races then - and winter has events too if you do not mind cold-weather conditions on the Front Range.
Will I get a shirt at these races?
30 of the 31 races say they give a shirt. One race has not published any giveaway details, so we do not know either way on that one. None of the races mention a finisher medal.
