Denver is about to host its very first HYROX race, and athletes across the metro are looking for a gym that offers official, coached group classes—not improvised workouts loosely inspired by the format. If you have been searching for a place to train, here is exactly where and when you can join group HYROX classes in Denver.
Denver's First HYROX Race Is Coming November 2026
HYROX Denver runs November 12–15, 2026, at the Stockyards Event Center (5115 Race Ct, Denver, CO 80216). It marks the first time the global fitness racing series has visited the Mile High City. Denver joins Tampa, Nashville, and Salt Lake City as new stops on the 2026 North American calendar.
The race format is standardized worldwide: eight 1-kilometer runs, each followed by one of eight functional workout stations—SkiErg, sled push, sled pull, burpee broad jumps, rowing, farmers carry, sandbag lunges, and wall balls. Divisions include singles, doubles, mixed doubles, relay, and adaptive categories, so the event is open whether you are chasing a podium or finishing for the first time.
With race day roughly five months out, now is the window to lock in structured training.
Why Official HYROX Affiliate Status Matters
Not every gym advertising HYROX prep is actually affiliated with the organization. Official HYROX affiliate status means a gym uses certified programming delivered through the HYROX Performance Hub—not self-designed workouts that borrow the name. Affiliates gain access to periodized programming, coach education resources, and race-day benefits for their members.
When you are evaluating gyms, ask a simple question: Are you an official HYROX affiliate? If the answer is vague, the programming likely is too.
Colfax Strong: Official HYROX Affiliate in Downtown Denver
Colfax Strong is an official HYROX affiliate located at 1516 North Emerson Street in Denver, Colorado. The gym's dedicated HYROX programming launches on June 18, 2026, giving members nearly five full months of structured preparation before the November race.
HYROX Class Schedule at Colfax Strong
The HYROX Training Club runs on a full Thursday slate plus a Saturday morning session:
| Day | Class Times |
|---|---|
| Thursday | 5:30 AM · 6:30 AM · 7:30 AM · 12:00 PM · 3:30 PM · 4:30 PM · 5:30 PM · 6:30 PM |
| Saturday | 8:00 AM |
That is nine coached sessions every week, spread across early morning, midday, afternoon, and evening windows so you can fit race prep into virtually any schedule.
What Makes the HYROX Training Club Different
- Official affiliate programming — workouts come from the HYROX Performance Hub, not improvised session plans.
- Coached every session — a certified coach leads every class and scales movements for all fitness levels.
- Large-group format — the classes are designed as a community-driven, large-group experience that is more accessible than one-on-one training.
- Race-day perks — members get access to early-bird registration codes for HYROX races and exclusive affiliate partner benefits.
- Altitude advantage — training at 5,280 feet builds an endurance edge. Athletes who prepare at Denver's elevation often see faster times when they race at lower altitudes.
Other HYROX Training Options Across the Denver Metro
Colfax Strong is not the only option in the region. Several other gyms across the metro serve athletes preparing for HYROX:
- Elite Performance Center (Centennial) — an official HYROX affiliate south of Denver that serves athletes in Cherry Hills Village, Englewood, Greenwood Village, and Littleton.
- Traverse Fitness (SoBo) — recognized in local HYROX circles for simulation frequency and structured programming in south Broadway.
- Arsenal Health & Fitness (Arvada / DTC) — offers HYROX-focused training across two locations.
- F45 locations — several Denver-area F45 studios run HYROX-branded class formats like HYROX Fridays and HYROX Strong through F45's partnership with HYROX.
Each gym differs in schedule, coaching depth, equipment, and whether it holds official affiliate status. If you are based in or near downtown Denver and want a full weekly class schedule with nine time slots, Colfax Strong's HYROX Training Club offers the widest selection of coached sessions in the city center.
How Much Lead Time Do You Need?
Most first-time HYROX competitors benefit from 12 to 16 weeks of structured preparation. If you already run and lift consistently, 8 weeks may be enough to build race-specific fitness. With programming launching June 18 and race day arriving November 12, Colfax Strong's schedule gives members roughly 21 weeks—more than enough time to build a base, peak, and taper.
Athletes who are newer to functional fitness can use the weeks leading up to the HYROX launch to build a foundation through Colfax Strong's other programming formats, including semi-private training, personal training, and community fitness classes.
Training at Altitude: What Denver Athletes Should Know
Denver sits at 5,280 feet above sea level. That altitude means higher perceived exertion, faster glycogen depletion, and greater fluid losses at the same training pace compared to sea-level locations. It demands smarter pacing and better hydration habits throughout your preparation.
The upside is significant: athletes who build their aerobic base at altitude carry a real endurance advantage when they race at lower elevations. Even for the Denver race itself, training locally means your body is already adapted, giving you an edge over visiting competitors who may arrive only days before the event.
