Running Metrics

Understanding your run data

Every HYROX event features 8 running segments and roxzone transitions. While the combined running + roxzone distance is fixed at 8.7km across all venues, individual lap lengths differ depending on the venue layout.

This means a single lap time cannot be directly converted to a per-km pace. To give you a fuller picture, we break your running down into two complementary metrics.

AVG. PACE

Overall pace across the 8.7km course

Divides your total running and roxzone time by the fixed 8.7km course distance. Because this distance is the same at every venue, Avg Pace is the most reliable way to compare performance between different races.

(Running + Roxzone) ÷ 8.7 km

Your result

36:57 + 5:13 = 04:50/km

AVG. RUN

Mean time per running segment

Your total running time divided by 8 laps, excluding roxzone transitions. Since individual lap distances vary by venue, this is a time average rather than a true pace. Use it to spot inconsistencies between your fastest and slowest laps within a single race.

Running Time ÷ 8 laps

Your result

36:57 = 4:37

When to use each

Use Avg Pace to track progress across seasons and compare results from different venues. The standardised 8.7km distance makes it a true per-km pace.

Use Avg Run to evaluate your pacing strategy within one race. A large gap between your best lap and your average signals room for more consistent splits.

Your Race Debrief

Here's what stood out and where to focus your training next.
Maximum Impact Focus
#1 Priority

Target 50m Sled Push for maximum race improvement. This station offers ~30s potential time savings due to poor relative performance.

Action Plan:

2–3 sessions/week: heavy prowler pushes (5x20–30m) + wall sits (3x45–60s). Emphasize bracing and short, powerful steps. Progress load weekly.

You're an Engine
#2 Priority

Your running is a major strength, but improving your strength-endurance will make you a more complete athlete.

Action Plan:

Focus on high-intensity circuits that mimic race conditions. Combine exercises like rowing, wall balls, and farmer's carries to build work capacity.
