Grand Slam Track

Grand Slam Track was announced in 2024 by American former Olympic champion sprinter Michael Johnson. The first season is due to run from April - September 2025. After being initially announced in February 2024, the name of the league and other details were announced at a June 2024 press conference in Los Angeles hosted by John Anderson.

Development
Former sprinter Michael Johnson announced in February 2024 his intention to launch a track and field league for 2025, which would include a series of events during the track season between April to September. Johnson is reported to be investing money in the League.

In April 2024, Johnson announced initial plans for the Track and Field League, including a total of $30 million in funding from investors and strategic partners. Winners Alliance is reportedly the lead investor and operating partner. Speaking at the 2024 World Athletics Indoor Championships, the President of World Athletics, Sebastian Coe, said "I welcome innovation. I also welcome external resource. If you’ve got a rising tide, everyone benefits".

The League was working in 2024 with the companies Doubleday & Cartwright, Two Circles, and SRK Strategies, to respectively concentrate on the graphics, marketing and public relations for the Track and Field League.

In May 2024, former middle distance runner Kyle Merber confirmed he was employed as Director of Athletes and Racing.

Aims
The announcement of the League in February 2024 came with the stated aims to increase and boost the sport of track and field in public consciousness and to promote the sport outside the tent-poles of popularity provided by the four-yearly cycle of Olympic Games. One of the aims is for the Track and Field League to resemble other sports leagues, with global athletes. The League is also designed to help athletes gain exposure and sponsorship opportunities.

Editions
The league officially launched in June 2024, prior to a planned debut season in 2025. Proposing four "grand slam" events a season, including one in Los Angeles, the track events are split into two-event leagues with each competitor taking part in two disciplines. Among the first athletes to sign-up for the events in June 2024 were Olympic champion hurdler Sydney McLaughlin-Levrone and British middle-distance world champion Josh Kerr.

Broadcast
In February 2024, Michael Johnson said that the Track and Field League has the goal to provide a TV-friendly product "to promote the sport’s biggest stars and draw new audiences through unique storytelling".
