When Olympic legend Michael Johnson launched Grand Slam Track (GST), the vision was bold: reinvent the sport with an athlete-first approach, big prize purses, and a reimagined global format. With a $30 million launch budget and promises to reward performance like never before, GST quickly gained traction. But after the abrupt cancellation of its final event in Los Angeles, questions are swirling—and athletes are asking where their promised money is.

The LA meet, originally scheduled for June 28–29, was expected to close out GST’s four-meet pilot season. Instead, the cancellation reportedly saved the organization upwards of $3 million, and left some top athletes publicly wondering when—or if—they’ll get paid.

Brazil’s Alison dos Santos, the 2022 world champion in the 400m hurdles, told Norwegian outlet NRKthat he is still waiting on his $250,000 prize check. He said the cancellation came as a surprise but remains hopeful that the money will arrive later this year.

Others were more skeptical. Emmanuel Wanyonyi, Kenya’s Olympic 800m champion and winner of the short-distance event at GST Kingston, admitted after his victory at the Bislett Games that he hadn’t been paid either. “It might come. Why shouldn’t it come?” he said. “They have to pay us. I’ll be patient and wait.”

American distance phenom Nico Young, who won the 3,000m at the Philadelphia Slam and followed that performance with a U.S. record in the 5,000m (12:45.27) in Oslo, offered a more cautious response: “I don’t know if I’m supposed to say anything about it. We’re working on it.”

Even those with positive experiences are waiting. Charles Philibert-Thiboutot, a two-time Olympian for Canada, praised GST after competing in Kingston. “Grand Slam Track was one of the best experiences I’ve had as a pro,” he told Canadian Running. “I’m sad to see it struggle, because I do think that’s the way athletes should be treated at the highest level.” Still, he acknowledged he hasn’t been paid yet—but was told the money is on the way.

An agent representing multiple GST athletes confirmed that only half of the prize money from Kingston has been paid, and that winners from Miami and Philadelphia are still waiting. Delays in payout aren’t uncommon in professional track, with 6–12 week lags the norm—but with Kingston now 11 weeks in the rearview, patience is thinning.

GST was originally backed by a $30 million budget, with $12.6 million earmarked for prize money—$3.15 million per event. The league also supported athlete contracts and high-end production values across its three completed events in Kingston, Miami, and Philadelphia.

In an email to NRK, GST spokesperson Callum Squires cited poor financial conditions at the LA venue as the reason for the cancellation. “The success of our three previous events has led us to make the difficult choice to end the pilot season and set our sights on 2026,” he wrote. “We will announce investors and new partnerships next week.”

Whether Grand Slam Track can recover and return stronger in 2026 may hinge on what happens next—and especially whether the league delivers on its most essential promise: paying the athletes who brought their best to the track.
