Hyrox Race Prep

Hyrox is eight 1 km runs, each followed by a functional station: SkiErg, sled push, sled pull, burpee broad jumps, row, farmers carry, sandbag lunges and wall balls. I come at it as a calisthenics person, so for me it’s mostly a pacing and running problem. Strength was rarely what held me back; heart rate was.

Pacing: do the maths, then run even

For a roughly 70-minute finish, every 1 km run needs to be around 4:30/km, with the stations fitting into what’s left. I trained that as a structured run: 1 km warm-up at an easy pace, 8 km at slightly faster than race pace with a negative split (start around 4:40 and finish faster), then an easy cool-down.

What the races taught me:

• Once heart rate spikes, it’s very hard to bring back down. Going out fast is a debt you can’t repay. Even pacing, then push at the end.
• The rower is the rest; wall balls are the hardest. Plan where you recover.
• Expect to be in high heart-rate zones for most of it, but keep the runs under control, and box-breathe (4-2-4) on the easier stations.
• With under a month to go, aerobic capacity won’t move much. Learn the pacing, keep long runs easy, and don’t wreck the rest of your training with hard “performance” runs.

Station benchmarks

Rather than full simulations every week, I benchmarked stations in short sets and fixed the weak ones:

• Wall balls: catch and drop into the squat in one movement; break them into planned sets (for example sets of 20, then 15s) rather than going to failure.
• Lunges: just step through; they’re simple but very lactic.
• Sled push: arms straight and low, good shoes. Sled pull: stay low, drive with the hips, use both arms.
• Burpee broad jumps: steady rhythm; don’t spike your heart rate early.
• Row: an easy pace to recover. SkiErg: it’s a hip hinge, not an arm pull; good technique saves a lot of energy.
• Farmers carry: run it.

A benchmark session might be four short sets of each of wall balls, easy rowing intervals, lunges and sled pulls, at technique-focused effort. Note which stations feel limited by technique and which by conditioning; they need different fixes (drills vs volume). Compromised running, a run straight after a station, is its own skill, so add short 1 km intervals into general workouts.

Hyrox does little for the upper body, so an upper-body add-on day (pressing, SkiErg, farmers carry) helps if you care about keeping it.

The taper

For the final three or so weeks I used a simple block: two Hyrox simulations a week, one long and one short zone-2 run, one interval session, and calisthenics parked for the month. One all-out session two weeks out, then an easy, technique-only session the week before and zone-2 runs only.

Taper rules that held up:

• Cut volume, keep intensity. One working set per exercise is plenty.
• Nothing heavy in the last four days. Mobility and strides to stay loose.
• Nothing new on race day: food, kit, drinks.
• Skip a planned session when joints and sleep are off. There’s no point burning out before the start line.

Fuelling

• Carb-load the day before. It made a noticeable difference to endurance.
• More than 2.5 hours before: a normal, carb-heavy breakfast (yoghurt, pancakes or toast with peanut butter, fruit).
• Within an hour: something small and easy, like a protein shake and a few dates.
• About 20–30 minutes before: caffeine if you use it, and a light snack.
• During and after: sweets in small bags and electrolytes during, protein after.
• No big meal within two hours of the start.

Balancing it with calisthenics

Every extra activity is a trade-off. Climbing, running, calisthenics and Hyrox all at once was simply too much, and that pattern (more activities, less recovery) is how training goes wrong.

• Keep calisthenics as the priority and run Hyrox prep alongside at low volume: strength around three times a week, running three times, most of it easy (Zone 2 Training).
• Eat at maintenance during a race block. Building muscle with that much cardio is hard; treat strength work as maintenance and skill practice, and prioritise recovery.
• Set an honest goal. I wasn’t competing, just trying to beat my own time, so “comfortably holding race pace for 8 km” was enough of a running target.
• Don’t race through existing pain. I once raced on a niggling ankle and finished with an ankle injury and weeks off. The lesson is the same one as in Deloads and Tendon Adaptation: the number one goal is not getting injured.
