Interval Run
The interval run alternates high-intensity efforts with recovery periods, building the VO2max and race-pace speed HYROX demands.
Definition
An interval run alternates planned work bouts with recovery. Work duration, speed or effort, recovery type and duration, repetitions and total load define the session. Not every interval session is high-intensity interval training.

Evidence and use
Reviews in recreational runners report protocol-dependent aerobic and running outcomes, not one universally superior format. Choose the session from goal, training status and recovery; no fixed 4-by-4, pace, heart-rate zone or weekly frequency guarantees VO2max, threshold or race improvement.
