Female Athlete Running Around Track

March 1 – HYROX Houston Simulation

Two weeks out from race day, I always like to run a full HYROX simulation. It’s been key in helping me gauge exactly where I’m at—mentally and physically—before race day. It also gives me a chance to test the gear and shoes I’ll be racing in so I can dial in what feels best on both the runs and the stations.

February 25 – Hyrox Turf Workout at The Yard

During one of my HYROX training sessions at The Yard in Arvada, I tackled a turf-based workout that included an all-out 500m sprint on the SkiErg. The mix of turf and rig training pushed my endurance and power, replicating the demands of race day. These sessions are a reminder that the best way to get comfortable with discomfort is to lean into it.

January 23 – HYROX All-Women Simulation

For my first-ever all-women Hyrox simulation, I trained at Arsenal Health & Fitness in Arvada, where 40 women showed up to train for Hyrox—either as solos or doubles. The energy was unreal! There’s something powerful about creating a space where women can push their limits without distractions (looking at you, beefy gym bros). Seeing this community come together for a brutal workout was inspiring.

January 18 – Strength Training at Kula Performance

At Kula Performance in Centennial, I focused on the strength-based portion of my training with Club Aion, a hybrid training program. Every heavy lift starts with dynamic warm-ups—because you can only squat heavy if you’re not tight as a board. Prioritizing mobility before loading up the bar has been a game-changer in my performance.
