Michael Johnson admits Grand Slam Track on hold until 2025 debts are paid

• Johnson says athletes owed millions in prize money

• LA finale cancelled after promised funding fell through

• Upstart series' 2026 season on hold until debts cleared

Grand Slam Track will not take place in 2026 unless athletes receive their prize money for this year, says founder Michael Johnson.

The four-time Olympic sprint champion confirmed the upstart track circuit has been unable to pay millions in appearance fees and prize money from its inaugural season and will not move forward until those debts are cleared.
