Four months ago, on the very same weekend, Eliud Kipchoge became the first human to run a marathon in under two hours, and fellow Kenyan Brigid Kosgei shattered the women's marathon record.

Why it matters: Kipchoge and Kosgei were both wearing Nike's controversial Vaporfly sneakers, which many believed would be banned because of the performance boost provided by a carbon-fiber plate in the midsole that acted as a spring and saved the runner energy.

  • Instead, World Athletics, track and field's governing body, published new rules last month regarding sole thickness and carbon-fiber plates that effectively rendered the Vaporfly legal.

Driving the news: Competing brands are now scrambling to build their own shoes to compete with the Vaporfly, and the clock is ticking.

  • The U.S. Olympic marathon trials are this weekend in Atlanta, and shoe companies are still playing catch-up as they adjust to the new norm.
  • The Tokyo Olympic marathons are in August, and any prototype that a runner wants to wear must be available at retail by April 30 — a deadline that has grown increasingly difficult to meet as Chinese manufacturers combat the coronavirus.

What they're saying: While rival companies are confident that their carbon-fiber plate designs will eventually be on par with the Vaporfly, Nike's formidable lead has forced them to acknowledge the gap that currently exists.

  • The head of Saucony even went as far as to say she would be open to allowing one of her sponsored runners to wear a competitor's shoes if he felt he'd be at a disadvantage without them.
  • "We would have to consider that," said Saucony president Anne Cavassa, per the Wall Street Journal.

The big picture: Running, the most elemental of sports, now faces the same "human ability vs. technological innovation" challenge that other sports like tennis (rackets) and swimming (full-body suits) have encountered.

The bottom line: The running industry is in the midst of a high-tech shoe revolution, and the outcome will affect everything from shoe sales and stock prices to who wins Olympic gold.

White House Chief of Staff Mark Meadows confirmed in court on Tuesday that President Trump's tweets authorizing the disclosure of documents related to the Russia investigation and Hillary Clinton's emails "were not self-executing declassification orders," after a federal judge demanded that Trump be asked about his intentions.

Why it matters: BuzzFeed News reporter Jason Leopold cited the tweets in an emergency motion seeking to gain access to special counsel Robert Mueller's unredacted report as part of a Freedom of Information Act request. This is the first time Trump himself has indicated, according to Meadows, that his tweets are not official directives.
