Sub 90 HYROX: How to Get Under 1h30
1 hour 30 minutes. This is the psychological benchmark in HYROX. Below this, you're in the "serious amateur competitor" group. Above it, you finish comfortably. Many athletes plateau around 1 hour 35-1 hour 40 and can't get below it. Here's exactly how to break through that barrier.
Sub 90, what does it mean in numbers?
To finish HYROX Open in under 90 minutes, here are your target splits:
| Segment | Target Time | Cumulative |
|---|---|---|
| 1 km run #1 | 4 min 30 | 4:30 |
| SkiErg 1 km | 4 min 30 | 9:00 |
| 1 km run #2 | 4 min 45 | 13:45 |
| Sled Push 50 m | 1 min 30 | 15:15 |
| 1 km run #3 | 4 min 45 | 20:00 |
| Sled Pull 50 m | 2 min 15 | 22:15 |
| 1 km run #4 | 4 min 45 | 27:00 |
| Burpee Broad Jumps 80 m | 5 min 30 | 32:30 |
| 1 km run #5 | 4 min 45 | 37:15 |
| Rowing 1 km | 4 min 00 | 41:15 |
| 1 km run #6 | 4 min 50 | 46:05 |
| Farmers Carry 200 m | 1 min 30 | 47:35 |
| 1 km run #7 | 5 min 00 | 52:35 |
| Sandbag Lunges 100 m | 5 min 30 | 58:05 |
| 1 km run #8 | 5 min 10 | 63:15 |
| Wall Balls 100 reps | 6 min 00 | 69:15 |
→ Exit 8th station: 1 hour 09 min. Remaining are Roxzone transitions (8 × 30-45 sec) and the final sprint (200 m). Total: 1 hour 25 - 1 hour 28, including a safety margin.
Prerequisites for sub 90
Before aiming for sub 90, you must have:
1. An Open race finished in 1 hour 35 minutes maximum
Sub 90 requires a 5-10 minute gain. If you're starting from 1 hour 50 minutes, that's 20+ minutes to gain — aim for sub 1 hour 40 minutes first, then sub 1 hour 30 minutes.
2. A 5 km in 22 minutes or less
This is the running foundation. Sub 90 requires maintaining 4:45/km on average over 8 km after stations.
3. Tested muscular endurance at stations
You can do 100 wall balls in 6 minutes when rested. You can push the 152 kg sled in under 2 minutes.
12-week attack plan
To go from 1 hour 35 minutes to sub 90, plan for 12 weeks.
Phase 1 — Identify your weaknesses (W1-2)
Redo a complete HYROX simulation and note your splits per station. Identify the 2-3 stations where you lose the most time. This is what you will work on first.
Phase 2 — Weakness specialization (W3-7)
Specific work on your 2-3 weak stations:
- 2 sessions/week focused on these stations
- Dedicated volume + intensity
- Regular testing of the station's individual time
Phase 3 — Fast running (parallel to phases 1-3)
If your 5 km is > 22 min, you must work on your running. This is the area with the most potential gain for sub 90.
Typical running program:
- 1 long run (60-75 min)
- 1 interval session (5-6 × 1 km at 4:30/km pace)
- 1 tempo session (3 km at half-marathon pace)
- 1 easy session or rest
Phase 4 — Timed simulation (W8-10)
3 complete simulations at sub 90 pace:
- W8: 75% pace simulation
- W9: 90% pace simulation
- W10: 100% pace simulation
You will identify if the sub 90 target is realistic.
Phase 5 — Taper + race (W11-12)
Classic tapering in W11, race in W12.
Race strategy for sub 90
1st km: DO NOT start too fast
Number 1 mistake for sub 90: starting at 4 min/km because you feel good. You'll blow up at station 4. Start at 4:30/km, that's your target pace.
Stations: no breaks
For sub 90, every break is costly. Aim for 0 breaks on sled push, sled pull, farmers carry. Sandbag lunges and wall balls can be fragmented but minimized.
Wall balls: 4 sets of 25 reps
A strategy that works for 95% of sub 90 athletes: 25 reps, 5 sec breath, 25 reps, 5 sec, etc. No sets of 50+ before the race.
Return run: inverse pacing
Don't hit a 5 min/km on the 8th km. You need to finish strong, not dying. If you have to slow down, it's between station 5 and 7, not after.
The 5 mistakes that make you miss sub 90
- Starting at 4:00/km on the 1st km — you pay for it at station 4
- Attempting non-stop wall balls — you crack at 60-70 reps, lose 1 min
- Slow Roxzone transition (45+ sec) — total lost: 4-6 min in the race
- Not testing in simulation — you discover on race day that your target pace is unrealistic
- Ignoring nutrition / hydration over 8 km + 8 stations in 1 h 30
Your sub 90 kit
| Item | Sub 90 Specificity |
|---|---|
| Shoes | Lighter than for standard Open. See Shoe Guide |
| Tee | Light compression to optimize mechanics |
| Energy gel | 1 gel after station 4 (35 min) if you have tested it |
| Cap / headband | Essential for 8 km of intense running |
In summary
- Sub 90 = benchmark for serious amateur competitors
- Prerequisites: Open in 1h 35, 5 km in 22 min, 100% successful simulation
- 12-week plan: identify weaknesses → specialization → fast running → timed simulations → race
- Strategy: consistent pacing, 0 breaks on short stations, wall balls in 4×25
- Mistakes: starting too fast, slow transitions, not testing
Sub 90 is the threshold that separates those who "did HYROX" from those who "do HYROX". When you cross it, you change categories mentally.
