The Invisible Tacticians: A Cardboard Notebook and the Data of East African Women's Running

The notebook has no plastic cover. It is a piece of cardboard cut from a packing box, folded in half, held together with a rubber band, and inside are thirty-four handwritten pages in blue ballpoint: every two hundred metres, breathing rhythm, projected time, and a final column noting where she should sit on the track. I held it on an August afternoon in 2026, when the entire international calendar had been suspended indefinitely and almost nobody was asking East African women distance runners what they were thinking during a week without a race. The woman who wrote it was twenty-four, a 3,000 metres steeplechaser training in the highlands of western Kenya.

Those thirty-four pages contain not one line about emotion. No resolve, no overcoming, no dream. Only tactics: when to lift the pace, when to tuck to the inside rail, when to let a rival lead and when to leave her behind on the final bend. A twenty-four-year-old woman was building her own race model by hand, on cardboard, while the analytics departments of major meetings still described women's races with two words: "slow" and "tactical".

Athletics commentary has a line that circulates as a default: women's distance races are less compelling, because closing speed is lower, there are fewer surges, less drama. The line has been repeated long enough that nobody demands evidence for it.

The timeline of the sport says otherwise. The women's 3,000 metres steeplechase entered the World Championships for the first time in Helsinki in 2026, and only reached the Olympics in Beijing in 2026. It was the last women's event added to the track. For more than a century of modern athletics, a group of women athletes was excluded from the arena, and the reason had nothing to do with their speed. Nobody organised the race for them. Later, their marks were measured across seventeen years and the conclusion drawn that they had no history.

In 2026, holding a media credential at the World Cup in Russia, I did something small and silent: I started a stopwatch on every minute of commentary on European broadcasters. Six per cent of airtime dealt with tactics; the rest went to stars and beautiful goals. Over the same period, the African women's championship took place without a single international broadcaster carrying it live. Since then I carry a professional reflex: whenever I write about a men's event, I immediately ask what the equivalent number is on the women's side, and who is holding it.

On the track, that reflex leads to a larger void. Split data from East African women's finals barely exists in any open database. The cause sits elsewhere: nobody wrote it down.

Over three years I coded video of sixty-two women's finals at 3,000 metres, 3,000 metres steeplechase and 5,000 metres between 2026 and 2026, and set them beside sixty-two men's finals at the same distances. The method was crude: split the race at two hundred metres, log position, log time, identify the moment the race was decided.

Roughly seventy-one per cent of the women's finals in the sample were decided by a surge inside the final six hundred metres, against fifty-eight per cent on the men's side. The difference does not lie in women running slower. It lies in decisions being compressed into the closing stages, when the field is still dense and every tactical error is magnified. A race like that demands more judgement, not less.

What the coding gave me: the tactical depth of East African women's races lives in the final six hundred metres, not in the finishing time. Every aggregate metric the media reaches for — finish time, average speed, placing — erases the hardest part of the race.

In my sample, women's finals showed a negative-split rate (closing faster than opening) about nine percentage points higher than the men's. On the steeplechase track, with five barriers and a water jump every lap, pacing is not only about speed. It is a collision problem: which side to approach the barrier, which foot to land on, which lane to take into the water jump without losing momentum. Those calls are made ten times in a race, and not one row of the results sheet records them.

Another observation: measuring the final four hundred metres of medallists, the gap between the winner and the fourth-place finisher on the women's side was smaller than on the men's side in about sixty-three per cent of matched pairs. The margin between the podium and the edge of it is narrower. The race is more tactically demanding and is read as less compelling. That paradox only survives when nobody bothers to code the data.

Back to the cardboard notebook. In March 2026, with the international calendar suspended, rather than sitting still I collected amateur phone footage from twelve women's clubs in Kenya, Tanzania and Uganda. Nine of the eleven women goalkeepers I interviewed said they had written their own "tactical notebooks" during lockdown. I had never encountered that behaviour among male players in my own research. The forty-page report titled "The Invisible Tacticians" came out of that, and was later taken up as course material by a university in England.

When the competitions stopped, I watched the invisible tacticians start to speak. They did not go on television. They wrote on cardboard and hid the notebook at the bottom of a kit bag.

I carried the same question onto the track. The women who opened the path for East African athletics left little footage behind. Ruth Jebet, born in Kenya and competing for Bahrain, ran 8:52.78 in Paris on 27 August 2026 to break the world record in the women's 3,000 metres steeplechase. Two years later, on 20 July 2026 in Monaco, Beatrice Chepkoech took the record down to 8:44.32. Those marks sit in every database. The pacing decisions that produced them do not.

Faith Kipyegon ran 3:49.04 for 1,500 metres in Paris on 7 July 2026, and before that 4:07.64 for the mile in Monaco on 21 July 2026. These records arrived in the same period that carbon-plated shoes with supercritical foam midsoles became standard. Nobody has carried out the full technology deduction. When a woman breaks a record in a new shoe, most public reaction swings between two poles: worship or suspicion. Both skip the hardest question, which is what share of the mark came from the shoe and what share from tactical pacing.

Meanwhile, access to injury data on women athletes remains tightly controlled. A runner withdraws from a final with a single line: "injury" — no location, no severity, no recovery timeline. Medical confidentiality is necessary, and medical confidentiality also leaves fans and reporters blind. Federations release only what suits their image. Supporters receive one word and infer the rest.

There is a commercial paradox that deserves more attention. Broadcasters say women's athletics has no audience, and they do not broadcast it. Because it is not broadcast, no audience forms. The loop has been closed long enough to pass as an explanation, while the sporting value of a women's final with greater tactical difficulty is never used as a basis for pricing. Commercial value is being measured with what is easy to measure, rather than with what is worth measuring.

The first channel is always the hardest, but somebody has to hold the microphone. East Africa does not lack women's athletics talent; it lacks recorders. I am not looking for a level playing field. I draw the lines of the field myself, starting by sitting down in front of the footage and counting every two hundred metres, because a race nobody records will be retold through the prejudices of someone who never watched it.

The Invisible Tacticians: A Cardboard Notebook and the Data of East African Women's Running

What is changing does not come from meeting rooms. It comes from twenty-four-year-old women athletes who pencil a split table onto cardboard, carry it in a kit bag, and correct it after every defeat. When that generation walks onto the track with data of its own, the question will no longer be how fast they run. The question will be who is patient enough to sit and count in order to understand how they won.
