An enigmatic character, she was once described by a former coach as possessing "a difficult temper La Gazelle, as she was dubbed by the press, had denied Freeman the gold in Atlanta insetting a sizzling time ofthe fastest in a decade. But she had also brought out the best in Freeman, the nemesis she needed to push her to realise her own greatness.

From toFreeman won 41 out of 42 races she competed in. And she only qualified two months before the games began under the guidance of a new coach — the German Wolfgang Meier, husband and coach of m world record holder Marita Koch. Her stay in Sydney was brief, controversial and, for most of the time, a circus. He was staking out the airport one morning when he caught sight of her in the distance.

Days later, she packed her bags and left the country after claiming a man had broken in to her hotel room. Around the time Marita Koch started setting new records, a Canadian teenager was trying to make his own mark as a "very mediocre" and metre runner. Len Brownlie grew up in Winnipeg, the capital of Manitoba, a prairie city situated on the blustery eastern edge of the Great Plains.

He remembers athletics meetings being as much a contest against the elements as they were a battle between the fittest and fastest.

A degree in science followed, and then a masters. By the time he began his PhD, Brownlie was immersed in the world of kinesiology, the study of the mechanics of body movement. His thesis, submitted inwas titled "Aerodynamic Characteristics of Sports Apparel" and explored techniques in clothing design that could help downhill skiers, cyclists and runners reduce drag and go faster.

Out of the blue inBrownlie received a call from a man called Eddy Harber, a Brit who was working as a functional apparel designer for Nike, the sportswear company that helped ignite the jogging craze in the s. Harber asked if he thought there was any potential to improve sprint performances by tinkering with a runner's aerodynamics. Brownlie says he still cries every time he watches a replay of Freeman winning the m.

And also it was, kind of, the completion of my thesis," he muses. To understand what the Nike team was trying to achieve, you should know a little about fluid dynamic drag. When an object moves, the surrounding gas molecules in the airflow are disturbed and pass around that object forming what is known as a boundary layer. The point at which the boundary layer separates from the back of the object determines the drag.

Take the case of a runner. As she runs, high air pressure begins to form in front and low air pressure behind. The difference between the high and low pressure is what's called pressure drag — which comprises between per cent of the total drag. Less difference in pressure equals less drag which means less energy spent countering the drag, leaving our athlete with the ability to run faster or run for longer.

With increasing speed, frictional drag stays relatively constant while pressure drag increases. So most gains in drag reduction are obtained by tackling the pressure differentials. It turns out that moving objects with smooth surfaces, like skin for instance, create a bigger pressure difference and a larger low pressure wake area behind the runner.

What Brownlie's wind tunnel testing revealed is that if you cover a smooth cylinder with the right kind of fabric, at the right speed you can drop that drag by as much as 50 per cent. That is achieved by a process called "tripping the flow", deliberately switching an orderly air flow into a turbulent one at a point that delays the boundary layer separation.

This reduces the pressure differential and the size of the low pressure wake area. What the wind tunnel tests showed was that — and this may sound a bit crazy — different parts of the body are moving at different velocities. A pumping arm moves faster than a torso — as do thighs and shins. The Swift Suit team realised that to effectively minimise drag, they had to treat an athlete's body as a sum of its parts rather than as a whole.

And that the only way to "trip the flow" was by tweaking different fabric types with different degrees of roughness in a process of trial and error.
