Twelve weeks is the classic Hyrox preparation window — long enough for real physiological adaptation, short enough to hold focus. But a good 12-week plan isn't twelve identical weeks of "train hard." It's periodised: each phase has a different job, and the order matters. Here's how the four phases work and what each one should contain.
Weeks 1–3: Base
The base phase builds the engine everything else sits on. The emphasis is aerobic volume at low intensity — easy runs, steady SkiErg and rower work — plus foundational strength: squats, lunges, carries, and pulling patterns at moderate loads. This is also when you groove technique on the machines, because efficiency you build now pays off when you're exhausted later.
It should feel almost too easy. If week 2 leaves you destroyed, the plan is front-loaded and you'll pay for it in week 9. Most sessions stay conversational; one weekly session introduces light compromised running (station effort → immediate run) to start teaching your legs the sport's core skill.
Weeks 4–7: Build
Now intensity climbs. Runs become intervals at or near target race pace. Strength moves toward race-specific loading — heavy sled pushes and pulls, weighted lunges, wall ball volume. The compromised-run sessions get longer and more specific: not just "run after rowing" but sequences that mimic race segments, like sled push → 1 km → sled pull.
The build phase is where weak stations get fixed. If your grip dies on the farmers carry or your burpee broad jumps fall apart after 40 m, this is the window to attack it — there's still time for adaptation. (Not sure which stations to prioritise? The complete stations guide breaks down what each one demands.)
Weeks 8–10: Peak
The peak phase combines everything at the highest sustainable intensity of the cycle. The signature session is the race simulation: half or three-quarters of the race distance, at target pace, in race order. Two or three of these across the phase teach you pacing, transitions, and what your target splits actually feel like on tired legs.
Volume holds steady or drops slightly while intensity peaks. Recovery becomes a discipline: sleep, easy days that stay easy, and no hero sessions. The fitness you race with is already mostly built — the peak phase sharpens it.
Weeks 11–12: Taper
Volume drops 40–60%, but intensity stays — short, sharp touches of race pace keep the system primed while fatigue drains away. The last hard session lands about 7–10 days out. Race week is short runs, light station touches, and trusting the work. You should feel restless and slightly under-trained. That's what peaking feels like.
How the weekly structure changes
A typical 4-day split across the phases
Across all phases, a 4-day week usually keeps the same skeleton — one easy/long run day, one strength day, one interval/compromised-run day, one hybrid or simulation day — while the content inside each slot evolves. Base: the interval day is light and technical. Build: it's race-pace work. Peak: it's simulation. Taper: it shrinks to sharpeners. If you're new to the sport, our beginner's guide shows what the base-phase week looks like in full.
Why generic 12-week templates fall short
The structure above is universal; the numbers inside it are not. A 60-minute-target athlete and a 100-minute-target athlete need different paces, loads, and volumes in every single session. A template can't know your weak stations, your training days, or your equipment. And it can't adjust when life happens — a missed week, an illness, a breakthrough.
That's the problem RoxRoute was built to solve: a plan periodised around your race date, calibrated to your level, that targets your weakest stations — and adapts week by week as you train.
RoxRoute builds a personalised, periodised Hyrox plan around your exact race date, fitness level, and weak stations — in about 60 seconds. Week 1 is free.
