Write down the date, Eliud Kipchoge has just made sporting and human history.The indefatigable Kenyan has become the first person to ever run a marathon in under two hours, shattering his previous best of 2:00.25 from Nike's 'Breaking2' project two years ago.With numerous lessons learned from that agonising attempt in Monza, there were no mistakes this time around and Kipchoge crossed the line to great applause in a time of 1:59.40.Hosted through the streets of Vienna's Prater Park, Kipchoge was aided by some of the best pacemakers in the sport with five-time Olympians and world champions amongst the field.The likes of Bernard Lagat, Austine Choge and the three Ingebrigsten brothers ensured that Kipchoge maintained the necessary pace to break through athletics' last great barrier.

Kipchoge makes sporting history in Vienna

And the splits required to do so are beyond the comprehension of us mere mortals.

Kipchoge had to maintain an average pace of 17.08 seconds for each 100 metres, 68 seconds for every lap of an athletics track and 28 minutes and 26 seconds for every 10 kilometres.

And that's exactly why pacemakers needed to be rotated in and out, supported by a laser-projecting car, because there's literally no one on the planet that can keep pace with him.

It was the Sir Roger Bannister moment of our era and Kipchoge had long since taken inspiration from that mythical, inaugural breaking of the four-minute mile in 1954.

World record won't officially count

However, this is something all together more impressive, something that scientists have doubted is even possible or at least not until far-flung years like 2050.

Will it count as an official world record? Sadly not, rather Kipchoge's clocking of 2:01.39 at last year's Berlin marathon - almost beaten by Kenenisa Bekele one year one - will endure as the gold standard.

The IAAF invalidates races where pacemakers are injected after its inception, although Lord Seb Coe admitted at the 2019 World Championships that the rules could be altered.

But who cares anyway? The fact of the matter is that Kipchoge covered the marathon distance in under two hours, becoming the human to do so and lest history forget it.
