How you prepare a football match seven time zones from home

01The problem: kicking off at 15:00 when your body thinks it is 08:00

The match was Sunday at 15:00, Khabarovsk time. In Sochi, at that moment, it was 08:00 in the morning.

That meant my players were going to compete in the window in which a footballer performs worst. This is not an impression: human physical performance follows a fairly stable daily rhythm, peaking in the late afternoon — when core temperature and neuromuscular activation are highest — and bottoming out in the early morning. At that internal hour there is less strength, less joint flexibility, slower reaction speed, and the same workload feels harder.

Then add the rest:

• Hormonal desynchronisation. Cortisol, growth hormone, melatonin — the whole cycle keeps running on origin time for days. Growth hormone is released mostly during deep night-time sleep; if sleep is disrupted, muscle repair suffers.
• Appetite and digestion. One of the most common symptoms of jet lag is losing your appetite exactly when you need to eat. A footballer who does not eat breakfast properly on matchday arrives empty.
• The cognitive side, which is the worst of it. Complex tasks — reading a passage of play, deciding when to press, anticipating — degrade faster and further than simple ones. We played a high-pressing, possession-based game. That style does not forgive a tenth of a second of hesitation.

And the decisive constraint: we landed roughly 30 hours before kick-off. The rough rule in the literature is that the body needs around one day per time zone crossed to fully resynchronise. Seven zones, seven days. We had thirty hours.

This matters, because it frames everything else: complete adaptation was impossible. No plan, good or bad, could have achieved it. The question was never how do we adapt. It was how do we lose as little as possible.

02Step one is doing your homework

A coach is not a physiologist. I am not one. When a problem like this lands on your desk, the first move is not to have an opinion — it is to go and find out what is known.

We searched with every tool we had: scientific databases, published reviews, consensus documents, material from performance physiologists, and also the artificial-intelligence tools that existed at the time, which for this purpose do exactly what a very fast search engine does — locate literature and organise it. What came out of that was an internal report of more than eight thousand words, with the sources cited one by one.

What that literature says is fairly consistent. The most cited reference in the field is the consensus statement Managing Travel Fatigue and Jet Lag in Athletes: A Review and Consensus Statement (Janse van Rensburg et al., Sports Medicine, 2021), signed by more than twenty performance researchers and clinicians from a range of countries. The idea of advancing sleep phase with morning bright light before eastward travel has been studied for over twenty years.

Search tools decide nothing. They find. Everything that comes after is the coaching staff’s job, and that is the part that is actually hard.

03From the literature to the dressing room: the filter

Between a scientific report and a footballer there is an enormous gap. Closing it is the craft. In this case it meant five things:

• Filter for context. The literature speaks in general terms; you have a specific case. Our style of play, our kick-off time, our real itinerary — Sochi–Moscow at 13:45, a 2 h 45 min layover, an eight-hour Moscow–Khabarovsk leg — our fixture list with matches in both preceding weeks, and the supplementation rules that applied to us. Half of what you read does not apply. It has to go.
• Turn it into decisions. “Morning bright-light exposure” is not an instruction. “08:30, fifteen minutes of easy jogging outside the hotel” is. A plan that does not state a time and a place does not get executed.
• Cut it down. From over eight thousand words to eight slides a footballer reads in three minutes. If it does not fit into three minutes, it does not land.
• Translate it properly. The material was issued in Spanish, Russian and English. A plan the squad cannot read in its own language is not a plan, it is a file.
• Validate it with the right people. Melatonin and caffeine are prescribed by the medical and fitness staff — not by the head coach, and certainly not by a piece of software. That conversation is mandatory, and it is where several ideas get dropped.

And one last thing, which is not technical: explain it to the players. A footballer whose wake-up time you shift for a week without telling him why will follow it badly. A footballer who understands what is happening to his body will follow it well. A large part of whether a plan like this works is decided right there.

Three languages The same plan, issued in each player’s own language

04The plan, hour by hour

This is what the squad received.

05The three decisions people question most

Of everything above, three things tend to jar with anyone who has not made a trip like this. They are worth explaining, because they hold up the rest.

06What you cannot control, and it is worth saying so

It would be dishonest to present this as an exact science.

With seven time zones and thirty hours, complete adaptation is impossible, and no plan achieves it. The most you can aim for is to cut the loss.

The response is highly individual. Some players sleep eight hours sitting upright on a plane; others do not close their eyes. Some tolerate melatonin well; others wake up groggy. That is why the plan carried margins — optional naps, minimum doses, individual calls — and why the staff has to keep asking, player by player, throughout the trip.

And there is no way to know how much of it worked. You cannot make the same journey twice, with and without a plan, and compare. We won 0–1 in Khabarovsk, but it would be dishonest to present that result as validation of anything: one match does not validate a protocol. The only thing I can state with confidence is that it was approached with judgement, in writing, using the best available information — rather than boarding the plane and hoping.

07What I took away from that trip

Three things, and they apply to any coaching staff facing this:

• Start seven days out, not on the day of the flight. Almost everything you gain, you gain in the preceding week, by shifting the whole day little by little. By the time you board, most of the work is either done or no longer possible.
• The plan has to fit on one page and be in the player’s own language. Everything else is internal documentation. The quality of a travel plan is not measured by how comprehensive it is, but by how much of it the squad remembers at six in the morning in an airport.
• Do your homework, then decide yourself. Searching well is cheap and faster now than it has ever been. But no search knows your squad, your flight, your fixture list or your doctors. Information is looked up; decisions are made, signed, and answered for.
