Hyrox is one of the most masters-friendly fitness races in the world. The race format doesn't change with age; the weights and the finish categories do. That means a 52-year-old can train for the same event their 28-year-old training partner is doing, and finish on the same start line.
But the training has to change. Aerobic capacity, recovery rate, and muscle protein synthesis all decline with age. The athletes who race well at masters do less of the wrong work and more of the right work.
The masters categories at Hyrox
Hyrox uses five-year age bands for masters: 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65+. Each category has its own results board. Athletes typically race against others within five years either side, not against the overall field.
Weights for masters are scaled in some categories. The sandbag lunges and farmer's carry weights tend to drop in the older brackets; sled loads sometimes too. Check the official rules for your specific age group and category (open vs doubles vs pro).
The practical upshot: a strong 55-year-old isn't competing against 25-year-olds. They're competing against other 55-year-olds with similar weights and similar pacing standards.
What changes after 40
Three physiological shifts that matter for Hyrox training:
1. Aerobic capacity (VO2 max) declines roughly 1% per year after 30 if you do nothing. Hard interval training slows this to 0.3-0.5% per year. The good news: you can preserve a huge percentage of your engine into your 60s. The training to do so is intense, brief, and infrequent.
2. Recovery time between hard sessions extends. A 28-year-old can do hard sessions back-to-back. A 48-year-old needs 48-72 hours between similar efforts. Stacking hard days is the fastest way to get hurt.
3. Connective tissue (tendons, ligaments) adapts slower than muscle. Strength comes back faster than tendons can support it. A common masters injury pattern is tendinopathy from a programme that loaded muscle correctly but underestimated tendon adaptation time. Build slow.
The masters training week
For most masters athletes targeting a finish (not a podium), 4-5 sessions per week is the sweet spot. Sample:
- Mon: Hyrox-specific intervals: 4×500 m run + sled push between. 50 min.
- Tue: Easy aerobic run or cycle, 40-60 min. Heart rate < 140 bpm.
- Wed: Strength: trap bar deadlift, single-leg work, push-press, accessory pulling. 50 min.
- Thu: Active recovery: mobility, walk, easy swim, or full rest day.
- Fri: Wall ball + farmer carry combo session, 35-45 min.
- Sat: Race simulation OR long easy aerobic (75-90 min). Alternate weekly.
- Sun: Rest or easy walk.
Compare that to a typical 30-year-old plan: same number of sessions, but the rest days are properly off rather than active. The hard sessions are spaced two days apart minimum.
Strength training matters more, not less
After 40, sarcopenia (muscle loss) starts to compound. The single most protective intervention is heavy strength training, twice per week, year-round. For Hyrox masters specifically:
- Heavy hinge. Deadlift or trap-bar deadlift, 3-4 sets of 3-5 reps, twice per week. This protects your sled push, your wall ball, and your spine.
- Single-leg work. Bulgarian split squat, step-ups, lunges. Asymmetries get worse with age; single-leg work catches them.
- Pulling. Pull-ups (assisted or unassisted), rows, face-pulls. The pull volume in Hyrox racing exceeds most masters athletes' baseline; you'll feel it during the sled pull station otherwise.
What to skip: max-effort lifting (anything above 90% of 1RM). The return is small; the joint cost is high.
Recovery is the limiter
The single most-asked question at our coaching calls from masters athletes: "Should I train through this tiredness or rest?"
Rule of thumb: if you wake up two consecutive mornings with a resting heart rate 10+ beats above baseline, rest for two days. If you wake up with a sore joint that wasn't sore before, rest the joint for three days minimum (cross-train other body parts).
Sleep is the recovery lever. Eight hours is the floor for masters athletes in a hard training block. Seven hours and you're losing 30% of the adaptation you trained for. Hard truth, well-documented in the sleep-science literature.
Nutrition shifts
A few quiet truths for the masters athlete:
- Protein needs are higher per kg of body weight. Aim for 1.6-2.0 g per kg per day during a training block. Most masters athletes are under-eating protein.
- Carbohydrate around training is still high-value. Don't go ultra-low-carb during a Hyrox build; you'll under-recover.
- Alcohol becomes more expensive. A single night of three drinks costs a masters athlete ~25% of their next-day session quality. A 25-year-old loses ~10%.
Race day for masters
Pacing matters more than at any other age. The masters athletes who blow up at race-day are the ones who started station one at 90% effort. The masters athletes who finish strong started at 75% and held it.
Mental shift: you're racing the back half. Save legs for the wall ball, save grip for the farmer's carry, save lungs for the last 1 km run.
The honest summary
You can race Hyrox at any age the federation will admit you to (it's wide). The training is different from what worked at 28. Less volume, more sleep, more strength, fewer all-out sessions, more disciplined recovery.
The masters athletes who race best are the ones who treat the training as a long game. Eighteen months of sensible work outperforms twelve weeks of trying to feel young again. Your future self at 60 thanks you for the boring base sessions.

Frequently asked
Is Hyrox safe over 50?
For most healthy adults with a base of regular training, yes. Get a GP sign-off if you have heart, joint, or metabolic conditions. The masters categories are designed to make race-day weights manageable so most age-related injury risk comes from over-training in the build, not the race itself.
What's the difference between Masters and Open?
Masters at Hyrox typically use the same race format but with adjusted weights and a separate finish board. Categories are usually 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65+. Check the official Hyrox rules for the exact splits and weights at your event.
How many days a week should I train at 50+?
Three quality sessions plus two easy aerobic days works for most. Four hard sessions per week is the point most masters athletes start over-training. Sleep matters more than the extra session.
Do I need a coach?
Not strictly. A structured 12-week plan plus a willingness to skip a session when you're tired will out-perform a hard-driving coach who pushes you when you should be resting.
