Sports scientist, Dr Ross Tucker spoke to John Maytham about some of technicalities that may have influenced Kipchoge's impressive run.

Tucker says the presence of a vehicle in front of the athlete provided a break against wind resistance.

That is my reading of it based on the mathematics and the engineering of what it involves, for an athlete to run at that speed they would probably spend around 15% of their energy just overcoming air resistance so if you take that away it's reasonably easier.
