Work Rate and Metres Per Minute

The running metric that captures effort independent of time on the pitch

6 min readIntermediate

Metres per minute (m/min) is the GPS metric that best captures a player's running effort independent of how long they are on the pitch. Unlike total distance — which rewards players who simply play more minutes — m/min reveals the true intensity of effort. This card explains how to calculate, interpret, and apply m/min data across positions, and examines its limitations alongside complementary metrics.

What metres per minute measures

Metres per minute (m/min) is calculated by dividing the total distance a player covers by the number of minutes they are on the field. It provides a per-minute rate of locomotor activity that allows fair comparison between players who play different durations — a starter who plays 80 minutes, a replacement who plays 25 minutes, and a player who is substituted at half-time.

Without m/min, a starter who covers 6,000 metres in 80 minutes appears to have outperformed a replacement who covers 2,000 metres in 25 minutes. But the m/min calculation reveals the replacement was working at 80 m/min compared to the starter's 75 m/min — a meaningfully higher intensity.

Calculation methods

There are two primary methods for calculating m/min, and they produce different values. Coaches must be consistent in which method they use to ensure meaningful comparisons across matches and seasons.

MethodCalculationWhat it capturesBest use
Total m/minTotal distance / total playing minutes (including stoppages)Overall work rate relative to time on the fieldComparing players within the same match; season-long monitoring
Ball-in-play m/minTotal distance / ball-in-play minutes onlyTrue running intensity during active play — excludes stoppages, conversions, and injuriesComparing across matches with different stoppage rates; evaluating genuine effort

Ball-in-play m/min is the more revealing metric because it removes the variability caused by different stoppage rates. A match with 35 minutes of ball-in-play time will produce lower total m/min values than a match with 45 minutes of ball-in-play time — even if the players ran at the same intensity during active play.

What changes m/min by position

Metres per minute varies by position because the roles are different, and the ordering below follows from what each position spends the match doing. Build the numbers themselves from your own GPS data rather than borrowing a professional squad's: three or four matches per position group gives you a reference that reflects your competition, your game plan, and your pitch.

Position groupWhere the work rate sitsKey factors
Props (1, 3)Lowest in the teamScrummaging and ruck work dominate; high static effort the metric never sees
Hooker (2)Low, a little above the propsBall-carrying and around-the-park mobility add running to the set-piece load
Locks (4, 5)Low to moderateSignificant lineout and ruck contribution, less open-field running
Flankers (6, 7)Highest among the forwardsHeavy running load combined with contact demands
Number 8Between the locks and the flankersDepends on playing style
Scrumhalf (9)HighConstant movement around rucks; less high-speed running than the backs outside
Fly-half (10)HighDefensive and kick-chase duties add a high-speed component
Centres (12, 13)HighSubstantial collision load alongside the running; inside centre lower than outside centre
Wings (11, 14)Among the highestSignificant high-speed and sprint distance
Fullback (15)Among the highestCovers the most ground because of the sweeping role

High-speed metres per minute — the quality indicator

Total m/min includes all movement — walking, jogging, running, and sprinting. A player who jogs constantly will have a high m/min but may not be contributing high-quality running effort. High-speed metres per minute (HS m/min) isolates the running done above a speed threshold (typically 5 m/s or 18 km/h) and divides it by playing time.

HS m/min is a better indicator of physical quality than total m/min because high-speed running is metabolically expensive, requires neuromuscular freshness, and is directly related to match-critical actions (chasing, covering, breaking the line, getting back in the defensive line). The share of running done above the threshold is small for everyone and grows as you move from the tight five out to the back three, so a prop's HS m/min only means anything next to another prop's.

Individual m/min values from a single match have limited value because of the contextual factors that influence running output (opposition quality, match score, weather, tactical approach). The true power of m/min emerges when tracked across a season as a rolling trend.

  • Establish a baseline — calculate the player's average m/min across the first 4–5 matches of the season. This becomes the reference point for monitoring.
  • Track weekly variation — a drop from baseline in a single match may be contextual (conservative game plan, leading comfortably). The same drop sustained over 3+ matches suggests accumulated fatigue rather than tactics.
  • Monitor high-speed m/min separately — total m/min may remain stable while HS m/min declines. This pattern indicates that the player is maintaining their movement volume but losing the ability to produce high-intensity running — an early sign of fatigue or overreaching.
  • Compare training to match demands — if a player's training m/min consistently exceeds their match m/min, training may be too intense. If training m/min is consistently below match demands, the player may be underprepared for match intensity.

Limitations of metres per minute

While m/min is a valuable metric, it has significant limitations that coaches must understand to avoid misinterpretation.

  • Does not capture contact work — a prop who makes 15 tackles and clears 12 rucks will have a low m/min but has produced enormous physical effort. Contact demands are invisible to distance-based metrics.
  • Does not capture static efforts — scrummaging, mauling, and wrestling at the breakdown involve high force production without meaningful distance covered. Positional comparisons using m/min alone are inherently unfair to tight-five forwards.
  • Context dependency — a team defending a narrow lead in the final 20 minutes will produce lower m/min than a team chasing the game. The metric must be interpreted in context.
  • Threshold sensitivity — changing the high-speed threshold from 5 m/s to 5.5 m/s moves every HS m/min value in the squad, far enough to invent a trend that is not there. Consistency in threshold selection is essential for longitudinal monitoring.
  • Individual variation — players with different running styles (longer stride vs higher cadence, efficient movers vs less efficient movers) produce different m/min values at the same perceived effort.
