90-Minute HYROX Endurance Builder, a running and endurance HYROX workout

90-Minute HYROX Endurance Builder

Ninety continuous minutes at genuinely easy effort, rotating between running, rowing and skiing so no single tissue takes all the load. This is the aerobic base session that makes a 90-minute race feel survivable instead of desperate.

01

Warm-up

10 min

The first ten minutes are the warm-up. Do not skip them by starting fast.

  • Walk then easy jog 1 set · 10 min Heart rate should settle around zone 2 by minute 10.
02

Main aerobic block

70 min

Keep heart rate in zone 2. If you cannot hold a conversation, you are going too hard.

  • Run Block 1 · 20 min Easy. Aim for 60 to 70% of max heart rate.
  • Row Block 2 · 15 min Damper 4. Low stroke rate, around 20 to 22 spm.
  • Run Block 3 · 15 min Same pace as block 1. If it has drifted slower, that is fatigue talking.
  • SkiErg Block 4 · 10 min Steady. Full range, do not shorten the pull as you tire.
  • Farmers carry intervals Block 5 · 10 min, 100m carry / 100m walk Moderate weight. Grip endurance under aerobic fatigue.

Cool-down

  • Walk 1 set · 6 min
  • Full lower-body stretch 1 set · 4 min

Coaching notes

  • Easy means easy. The temptation to push in the middle 30 minutes is what turns a base session into a junk session.
  • Eat and drink during this one. 40 to 60g of carbohydrate per hour, and practise the exact products you will use on race day.
  • One session like this per week through the base phase does more for your race time than any amount of extra station work.

Questions people ask

How do I scale this?
Sets, reps and rest are written for a advanced athlete. Scale the load first and the rest second. If the movement falls apart, drop the weight before you add rest.
Where does this fit in a plan?
One session is a session. Sequence it into a week built around your race date and your weakest station on the training plan, or let the generator write one in the same format around your kit and time.
