Reigning Olympic champion Eliud Kipchoge narrowly failed in his attempt to complete the marathon under two hours on Saturday, finishing in a time of 2hr 00min 24sec.
Organizers first listed his time as a second faster, then changed it to 25 seconds off the 2-hour mark.
In their pursuit of sporting immortality the trio will need to set a ferocious pace of 4min 34sec per mile - seven seconds quicker than the pace of the existing world record of 2:02:57 set by Dennis Kimetto of Kenya at the 2014 Berlin Marathon.
Kipchoge competed with Ethiopia's Lelisa Desisa and Eritrea's Zersenay Tadese during the event, designed by Nike to cultivate the first marathon finish in less than two hours. The race used pace runners and a hydration strategy that disqualifies it for an official record, but the company refuted the suggestion that it's a marketing stunt created to showcase its new Zoom Vaporfly Elite more than the runners who wear the shoe. That move was created to help the runners more effectively maintain the rapid pace, but it also disqualified the competition from world record status; world records may only be set in events where all runners enter at the start.

Jenna Collins, Larkin, and O'Sullivan accounted for all six of the team's assists with each player dishing out two helpers. HPU was one-and-done in its two previous trips to the tournament, in 2013 and 2014. "I felt good", Perez said.
Nike produced shoes to be worn by the athletes making the attempt, the "Zoom Elite", pitched as the ideal blend of weightlessness, energy return and aerodynamics. That leaves roughly four minutes to trim off the current world record to achieve maximum running efficiency in a marathon.
Kipchoge's run at two hours was an impressive athletic feat. Nike's rival Adidas is preparing runners to break the two-hour mark in natural race settings. Nike would be happy just to break the two-hour mark.

Kipchoge needed an average of 2:50 per kilometre - an improvement of around 2.5 per cent on Kimetto's record.
Supported by a Nike effort that for months has sought to best control the variables that can impact performance, the Breaking2 athletes made their attempt without spectators in 17.5 laps around the Formula One track in Monza, Italy. They tested and integrated insights across the Nike Breaking2 project, gathered new data and observed first-hand the athletes daily training regimens and lifestyles, constantly looking for avenues where support could be provided. As the event wore on, Desisa and Tadese dropped off the pace, leaving only Kipchoge to assault the mark. "But I've never seen anything like what we saw today". Roger Bannister's four-minute mile, Jim Hines's 10-second 100m, and Paula Radcliffe's unprecedented 2:15:25 marathon all redefined the barriers of human potential. "But the performance itself must adhere to the conditions around world records, or it's meaningless".
