How do you beat Usain Bolt? Short of knotting his laces together or slipping him a pre-race laxative, it’s a daunting question for the Jamaican’s 100m rivals.
The US contenders will be hoping their team's Nike Pro TurboSpeed suit will at least go some way to bridging the gap.
Billed as “faster than skin”, the polyester one-piece is characterised by a series of enhanced dimples to improve the body’s aerodynamics.
Nike’s speed boffins in Oregon put in excess of 400 different surfaces through more than 1,000 hours of wind tunnel research.
The golf-ball inspired texture is located where drag is greatest — arms, shoulders and calves — and Nike claim the resulting all-in-one piece is 0.023 secs faster over 100m than its previous track and field best.
The suit’s even got its labels on the outside, to avoid any chance of annoying itches before the race.
Whether it’s enough to stop Bolt winning is another matter, of course. For that, a traffic jam on the Mile End Road might be a safer bet.
