How to run the fastest marathon ever

[Some fascinating techniques](https://www.theguardian.com/sport/2017/may/06/eliud-kipchoge-misses-out-on-sub-two-hour-marathon-by-2-seconds):

> At the start the three athletes were immediately joined by six pacers, who adopted an arrowhead formation behind a Tesla electric car with a giant clock timer on it. Wind tunnel studies show that this formation would help them as it saves energy…

> Kipchoge was also using a new carbohydrate-rich sports drink, delivered by helpers on mopeds so he did not have to slow down…

> Then there was the use of Nike’s Zoom Vaporfly Elite shoes, which some have suggested should be illegal because they contain a special curved plate that allows runners to roll through instead of bending toes and losing energy.
