Quick summary
| Key message | What it means |
|---|---|
| 1. Plan your training | Split training into phases for strength, endurance and Hyrox skills. |
| 2. Time your meals | Eat a low-fat, high-carb meal 60-90 minutes before training. |
| 3. Start hydrating early | Drink steadily for 24 hours before a big session, with natural electrolytes. |
| 4. Time your caffeine | Take caffeine 30-60 minutes before training for focus and lower perceived effort. |
| 5. Track your cycle | Adjust intensity and recovery to the phases of your cycle. |
1. Plan your training schedule
The Hyrox athletes who improve fastest plan their training. A schedule turns scattered sessions into steady progress.
Performance experts recommend personalised training plans built from blocks with a clear purpose. Each block develops strength, endurance or the technical skills Hyrox asks for.
Mix your session types. Easy long runs build your aerobic base, so you use oxygen better over long efforts. High-intensity intervals raise your threshold so you can hold a harder pace before fatigue hits, which you'll feel in the 1km runs after the sled.
Split your year into phases: base building, intensity, skills and recovery. Track your sessions, adjust based on what you see and stay flexible.
Tip: each week, include endurance, strength and Hyrox-specific work like sleds, wall balls and compromised running.
2. Eat 60-90 minutes before exercise
When you eat makes a big difference to how much energy you have in a session.
Research on competition nutrition recommends a balanced meal 3-4 hours before exercise, low in fat, high in carbohydrate and with some protein for steady energy.
What to include: • Complex carbohydrates for steady energy • Lean protein for your muscles • Little fat and fibre, to avoid stomach trouble • Foods that digest easily
If you're eating closer to training, 60-90 minutes before gives you time to digest while keeping your energy up, so you don't feel sluggish once you start.
Some athletes like a small carb snack, such as an energy bar or a piece of fruit, 30-60 minutes before training to keep blood sugar steady.
Tip: try different meals and timings in training to find what works for you before race day.
3. Hydrate early with natural electrolytes
Hydration starts well before your session. Preparing your body with fluids and electrolytes in advance helps your endurance.
Sipping fluids steadily through the day before helps your body absorb and hold water better than drinking a lot just before training.
How to hydrate: • Drink water when you wake up • Keep sipping through the day • Little and often • An isotonic drink can add some energy too
Electrolytes keep your fluid balance and muscle function on track and help fight fatigue. They control nerve and muscle function, keep you hydrated, help balance blood acidity and pressure, and support tissue repair.
Whole foods like coconut water, bananas, spinach and sweet potatoes give you potassium, magnesium and sodium with no artificial additives.
Tip: start hydrating 24 hours before a big Hyrox session and aim for pale yellow urine.
4. Match your caffeine to your session
Caffeine can help a lot in Hyrox, as long as you time it right.
What caffeine does: • Makes you more alert • Lowers perceived effort • Helps muscle recruitment • Sharpens focus
Research on pre-exercise nutrition shows it matters for high-intensity performance, and caffeine is a key part of it. The usual guidance is 3-6mg per kg of body weight, taken 30-60 minutes before your session.
Natural sources like green tea, coffee and guarana come with antioxidants and other nutrients as well as caffeine.
Tolerance varies. Some athletes get anxious or sleep badly with caffeine, so test it in training and adjust.
Tip: save caffeine for key sessions and races to keep its effect strong. Pre-Shot has 200mg caffeine in a 60ml shot, which makes the dose easy to get right.
5. Adjust timing around your menstrual cycle
Hormones shift across your cycle, and that affects how you train and recover. Use it to plan your hard sessions.
Cycle phases and training: • Follicular phase: often more energy and strength • Luteal phase: performance can dip • Oestrogen and progesterone affect metabolism • Recovery needs change through the cycle
Research on nutrition and exercise timing shows how closely your body's rhythms and performance are linked, and that a personal approach works best. In the first half of your cycle (follicular phase), you may recover faster and tolerate more pain, so it's a good time for your hardest Hyrox sessions.
In the luteal phase, as progesterone rises, you may need more recovery. Keep training, but adapt it: slightly lower volume or adjusted sessions that keep you progressing.
Tracking your cycle also lets you adjust food and fluids. Some athletes find more protein and complex carbs help in the luteal phase.
Tip: keep a training and cycle diary so you can spot your own patterns and plan around them.
6. Listen to your body before training
Reading your body's signals helps you tell a day to push from a day to back off.
Signs you're ready: • How tight your muscles feel • Mental clarity and focus • How responsive you feel physically • Easy, steady breathing • How hard a warm-up feels
Our pre-workout checklist covers body awareness in more detail. Some days you'll feel strong, and some days call for a more measured session.
Resting heart rate, soreness, sleep and motivation all tell you something. If you feel tired day after day, take extra recovery before your next hard session.
A daily training diary with your energy, effort and how you felt helps you learn your own rhythms.
Tip: rate your physical and mental readiness from 1 to 10 before each session.
7. Keep hard sessions away from bedtime
When you train affects how you sleep, and sleep drives recovery.
Why late hard sessions disrupt sleep: • Raised cortisol • Higher heart rate • Higher core temperature • A stimulated nervous system • Delayed melatonin release
Our pre-workout routine guide covers how training time affects recovery. Hard sessions within 3 hours of bed trigger a stress response that makes it harder to fall asleep.
Your body needs time to wind down. A late hard session keeps your nervous system switched on and can hold back melatonin, which hurts sleep quality, muscle recovery, hormonal balance and the next day's training.
Schedule your hardest Hyrox sessions earlier in the day. If evenings are your only option, keep them to easier work like yoga, stretching or mobility.
Tip: after training, wind down with gentle stretching, a warm herbal tea and less screen time.
Here's a summary of the 7 tips:
| Strategy | How to do it | What you get |
|---|---|---|
| Plan your training | Build blocks for base, intensity, skill and recovery. Mix easy long runs with intervals. | Better strength, endurance and Hyrox skills. |
| Pre-workout meals | Eat 60-90 minutes before, low fat, high carb, some protein. | More energy and endurance. |
| Hydration with electrolytes | Sip fluids steadily beforehand, with natural electrolytes. | Better fluid balance and muscle function. |
| Caffeine timing | Take caffeine 30-60 minutes before hard sessions, within your tolerance. | More alert, lower perceived effort. |
| Menstrual cycle | Go harder in the follicular phase and adjust in the luteal phase. | Better performance and recovery. |
| Energy cues | Check muscle tension and mental clarity before training. | Better sessions and less risk of burnout. |
| Session timing | Do hard sessions earlier in the day. | Better sleep and recovery. |

What are the signs that I am ready for a high-intensity workout?
Loose muscles, a clear head and feeling responsive. Rate yourself from 1 to 10 before each session.
Why should I avoid late evening workouts?
Late hard sessions raise cortisol and body temperature, which disrupts sleep. Train earlier when you can.
