Perspectives on the sport. Written by our Athletes, and our Founders.
In a base block, your body adapts to high volumes of easy aerobic work by building the machinery that produces and uses energy efficiently: more mitochondria, denser capillary networks, a stronger heart...
A 24-week HYROX build is for athletes starting from scratch, with little running background and no structured training, and it works by spending the first half building the ability to train before...
To periodise a half marathon and a HYROX, sequence them rather than train for both at once. Pick the earlier target, build to it, then use a short transition block to convert...
Overreaching is short-term, planned fatigue that recovery resolves in days to a couple of weeks; overtraining is a deeper, unplanned state that can take weeks or months to clear. The practical difference...
Week 1 of a new training block should feel too easy because you are re-establishing a baseline, not proving fitness. Starting light lets your body absorb the new stimulus, protects against early...
Most HYROX athletes can absorb two to three genuinely hard sessions per week. Beginners and busy professionals do best with two; well-recovered intermediate athletes can handle three; only advanced athletes with years...
Reverse periodisation, starting with short, high-intensity work and building toward longer volume as the race nears, makes only partial sense for HYROX. Because HYROX is roughly half running over 8km, most athletes...
A race-week taper for HYROX means cutting training volume by roughly 40-60% while keeping intensity sharp, so you arrive at the start line fresh but not flat. Drop the length of your...
A maintenance block holds your HYROX fitness through a busy patch by cutting volume sharply while keeping intensity: two or three short, focused sessions a week that preserve what you built without...
To come back after illness without losing the block, return gradually: resume easy aerobic volume first, delay hard sessions until symptoms have fully cleared, and adjust the block's timeline rather than trying...
Your mate's plan won't work for you because training age, how many years of consistent, structured training your body has behind it, changes what stimulus you need and how fast you recover....
The minimum effective dose for HYROX on 4-5 hours a week is three or four focused sessions that still follow real periodisation: one hard run, one strength-endurance session, one or two easy...
Intensity distribution across a HYROX season should be polarised, roughly 80% of your training time easy and around 20% hard, with the exact balance shifting block to block as you move from...
You periodise strength inside a HYROX plan by shifting emphasis across blocks: general maximal strength in the base, conversion to strength endurance in the build, and light maintenance in the race block...
A deload works by temporarily reducing training stress, usually cutting volume by around 40-60% while keeping some intensity, so accumulated fatigue clears and the fitness you built during hard weeks finally surfaces....
To periodise a year with two HYROX races, treat the season as two linked cycles: a full Base → Build → Race build into your first event, a short recovery and re-base...
