Grand Slam Track™ Miami Official Start Lists

Grand Slam Track™ Releases Official Miami Start Lists With Lane Assignments

 (April 24, 2024) - Grand Slam Track™, the global home of professional track competition launched by four-time Olympic Champion Michael Johnson, today officially announced the full field of 96 Racers & Challengers who will compete in the Miami Slam - the second event in the league’s inaugural season. The Slam will take place at Ansin Sports Complex in Miramar, Florida, from May 2–4. 

The group of Challengers announced today is headlined by international superstars such as Isabella Whittaker, Alaysha Johnson, Freweyni Hailu, Peter Bol, Trey Cunningham, and Kendall Ellis. Signed Racers Devon Allen, Clément Ducos, Jasmine Jones, and Luis Grijalva, plus previously announced Challenger Claudia Hollingsworth, will miss the Miami Slam due to injuries. An additional Challenger has been added to each of their Race Groups as a result. The competitors collectively represent a total of 24 different countries, exemplifying Grand Slam Track™’s reach as a global league.

“We’re delighted to announce the full field of competitors for the Miami Slam,” said Michael Johnson, the league’s founder and Commissioner. “Coming off the back of the Kingston Slam, our Sr. Director of Racing Kyle Merber has been hard at work continuing to sign the fastest humans on the planet as Challengers. They’re all excited to compete in Grand Slam Track™, knowing how big the honor of being a Slam Champion is. These competitors will put on a festival of speed that I know will entertain fans around the world, just like we did in Kingston. We’re excited to kick off our first Slam on U.S. soil, and I look forward to seeing all of our fans down there in South Florida.”

Grand Slam Track™ is also excited to welcome 2020 Olympic 400m Champion Steven Gardiner as a newly-signed Racer for the remainder of the 2025 season. The Bahamian won the gold medal at the 2020 Games in Tokyo, and was the 400m World Champion at the 2019 World Championships in Doha. He was also an Olympic bronze medalist in the 4x400m relay at the 2016 Rio de Janeiro Games and a gold medalist in the 4x400m mixed relay at the 2017 World Relays in Nassau. Replacing Quincy Hall as a Racer this season, Gardiner will be competing as part of the Men’s Long Sprints Race Group, facing off against Matthew Hudson-Smith, Muzala Samukonga, and Jereem Richards.

“I’m delighted to announce I’m joining Grand Slam Track as a Racer for the remainder of the 2025 season,” said Steven Gardiner. “I watched the Kingston Slam and knew I had to be a part of it.  The innovations to the sport and feedback from the athletes who participated makes me grateful for the opportunity to compete against the fastest men in the world on a regular basis. I can’t wait to see everybody down in Miami and, as usual, give my very best.”

Grand Slam Track™’s inaugural Slam took place in Kingston, Jamaica, earlier this spring. More than $3m in prize money was won by competitors. Three Slams remain in the 2025 season, taking place in Miami, May 2–4, Philadelphia, May 30–June 1, and Los Angeles, June 27–29.
