Have you ever wondered what it would look like if Usain Bolt's speed, style and details took to the track against Noah Lyles, Tyson Gay and Yohan Blake? Of course you have.
Bolt is an eight-time Olympic gold medal winner and the men's 100m and 200m world record holder.
His 9.58-second 100m time at the 2009 World Championships remains a truly iconic sporting moment and few sprinters have come close to troubling it, never mind beating it.
Australian teenager Gout Gout is on track to dominate men's sprinting in the future but Bolt's records stand strong.

With every great runner operating at different ages, in different conditions and with their own individual styles, it used to be impossible to know how one really stacked up against the next.
Thanks to the genius of epic YouTube simulation channel MotionAthlete, the quest to know who's best is getting ever more achievable.

One of the channel's stunning simulations is a speed comparison between Bolt and three other titans of the sprint world.

Noah Lyles is the reigning Olympic 100m champion and the American record holder in the 200m.
Tyson Gay holds the American record in the 100m. His time of 9.69 seconds is the second-fastest ever and is shared by Jamaica's Yohan Blake, a rival and training partner of Bolt.
But Bolt is 39, Blake is 35, Gay is 43 and Lyles is 28. Luckily, there's now a video that takes every last nuance of their peak performance and mashes them together in a fake but phenomenal speed comparison.
The video hits hard from the gun, adding Blake's PB to Gay's to compare two stunning but distinctive runs.

There is nothing to call between Blake and Gay from the first metre to the last but adding in Bolt's world record run changes everything.
When the relevant wind speeds are removed from the 100m simulation, the two Jamaicans take charge.
How does current star Lyles compare?
The simulation swaps Gay out for Lyles over 200m and the American record holder's PB is on the heels of Bolt and Blake at the finishing line – just.

Without the wind Bolt's margin of victory is even wider, but there's another wrinkle that MotionAthlete saw fit to iron out on Blake's behalf.
By correcting for Blake's notoriously slow reaction time out of the blocks, a story of missed opportunity emerges in the form of a dead heat with Bolt's world record that leaves Lyles in the dust.
