Premier League referees are being prepared like elite athletes, with pre-season camps in Spain, full-time training and an all-out six-minute Maximal Aerobic Speed test. Top-flight officials have met in Loughborough this week, and the work now looks a long way from the old idea that they simply turn up on Saturday afternoon.

The workload behind the badge

Sam Allison said referees now train full-time, “sometimes two, three sessions a day,” and Francis Bunce, the physical performance manager at Pro Ref, is happy to call them athletes. Bunce said: “They've all done so well to keep developing and they look like athletes on the pitch - they are athletes.”

The physical numbers back that up. Last season referees covered 3.6m metres in total, with an overall sprint distance of 12,136m. That is a lot of ground for a group whose job still ends with decision-making, positioning and control.

The MAS test shows the direction of the preparation. It is an all-out six-minute run, used to push the aerobic base officials need before the season starts.

Why the pace of the game keeps pushing officials

Sam Barrott said the modern bench has changed the demands on referees because fresh legs can swing momentum late in games. He pointed to five substitutions and the way late attacking changes alter the tempo.

Barrott said: “If three new attacking players are on that are all very pacey after 70 minutes you know they're going to change the way they play, they're going to try and push.”

That is why the conditioning work matters so much. Referees are monitored with heart rate and GPS technology, and Bunce said they still have to make decisions in a cool, calm manner even after running hard for long periods. Stuart Attwell's outing in Newcastle's 2-2 draw with Liverpool was a reminder of how much ground an official can end up covering in one match, as he registered the fourth highest distance of anyone on the pitch and was fifth for highest high-speed running.

The job is now built around repeated bursts, not just reading the game from the middle. The next step is the rest of the pre-season work, with officials already deep into the kind of fitness programme that sits behind the Premier League whistle.
