HYROX Running Speed Intervals
Eight 400m repeats at 5km pace with short recovery, built to raise the ceiling that your race pace sits under. The eight runs in a HYROX are run at roughly 85 to 90% of your open 1km pace, so the only way to run them faster is to make that open pace faster first.

Warm-up
10 minNever start intervals cold. The first rep should feel easy, not like a shock.
- Easy jog 1 set · 1200m Conversational throughout.
- Drills: A-skip, B-skip, high knees, heel flicks 2 sets · 20m each · rest walk back Quick ground contact. Think hot coals.
- Strides 3 sets · 60m · rest walk back Build to 90% over the 60m, then float out.
Main set
15 minTarget pace is your current 5km pace, not your 1km pace. Consistency across all eight beats a fast first two.
- 400m repeat 8 sets · 400m · rest 60s standing or walking Every rep within 3 seconds of the first. If rep 6 blows up, you started too fast.
Cool-down
5 min- Easy jog 1 set · 800m Slower than your warm-up jog.
- Calf and hamstring stretch 1 set · 45s each
Coaching notes
- Run the first rep 2 to 3 seconds slower than target. Nobody has ever regretted a controlled first interval.
- 60 seconds of recovery is deliberately short. It keeps the session aerobic rather than turning it into sprint work.
- Once you can hold all eight within 3 seconds, cut the rest to 45 seconds before you try to run them faster.
