Answer

I think the competition is the

Double Marathon (84.39km race)

Reasoning

If you take each athlete's record in their signature event and take the average speed over the distance of a double marathon, you would get the times listed (when rounded to the nearest second).

Example

Usain Bolt's record for the $100$m race is $9.58$ seconds for an average speed of $10.438$m/s. Doing this average speed for a distance of $84.39$km would give an overall time of roughly $2$ hours $14$ minutes and $45$ seconds.

Other athletes

Wayde van Niekert - 400m in 43.03 seconds.
David Rudisha - 800m in 1:40.91.

Noah Ngeny - 1000m in 2:11.96
Hicham El Guerrouj - 1500m in 3:26.00
Daniel Komen - 3000m in 7:20.67
Kenenisa Bekele - 5000m in 12:37.35
