Grand Slam Track, the much-hyped professional league founded by Olympic great Michael Johnson, is now fighting its way through bankruptcy court amid escalating accusations from vendors and creditors. What launched as an attempt to reinvent professional track and field, with lucrative prize money and a head-to-head format, has instead become a cautionary tale about the fragility of the sport's commercial model and the difficulty of building a stable business around it.

The numbers laid out in the Chapter 11 filing are stark. The league reported less than 50,000 dollars of cash on hand against debts estimated between 10 and 50 million dollars. After cancelling its final meet of the year in Los Angeles, Grand Slam is said to owe around 19 million dollars to athletes and vendors combined, including roughly 13 million in prize money and appearance fees across its three completed meets in Kingston, Miami and Philadelphia.

The most damaging allegations concern Johnson himself. Creditors claim he transferred 500,000 dollars to himself in June, only days before the Los Angeles meet was scrapped and at a point when the company already lacked the funds to pay its athletes and suppliers. Lawyers representing creditors argue the payment was tied to an unsecured note, was not approved by the board, and was made when Johnson knew the league was close to insolvency, a characterisation his side disputes.

For the athletes, the consequences are immediate and personal. High-profile competitors including Gabby Thomas, Emmanuel Wanyonyi, Alison dos Santos and Grant Fisher have spoken publicly about not having received money they were promised. The unpaid sums matter not only financially but reputationally, undermining the central pitch that Grand Slam Track could pay performers what their talent was worth and treat them as the professionals the wider sport so often fails to reward.

The broader lesson for professional track is sobering. Grand Slam arrived promising to professionalise and enrich a sport long starved of consistent investment, yet its rapid unravelling has deepened the very scepticism it set out to dispel. The league has signalled an intention to return for a 2026 season once its obligations are settled, but with trust eroded and bills unpaid, the credibility of any relaunch will rest entirely on whether the athletes left out of pocket are made whole first.
