After igniting the track world with a sold-out Miami Slam, Grand Slam Track is raising the stakes once again. The League recently announced major updates for the Philadelphia Slam, set to explode at historic Franklin Field May 31 and June 1.
This third stop in Grand Slam Track’s trailblazing inaugural season will feature a refined two-day competition schedule, new high-profile Challengers ready to disrupt the field, and a reimagined event format built for intensity, drama, and fan-first thrills.
“Coming off an amazing sold-out Miami Slam, we’ve taken time to celebrate the successes we’ve achieved in our inaugural season, but also have looked for ways to improve Grand Slam Track in real time,” said Grand Slam Track Founder and Commissioner Michael Johnson.
“We’ve said all along we want to listen to our fans, athletes, and coaches, and having heard feedback from various key stakeholders, we’ve made the decision to condense our schedule in Philadelphia into two, high-octane, and intense days of combat racing. We want to be the most flexible, adaptive, and fan-first league in sports, and we believe making these changes will improve the Grand Slam Track experience for all.”
New format. Higher stakes. Maximum speed.
In direct response to fans, athletes, and coaches, the Philadelphia Slam will run over two days instead of three, promising a tighter, more electric viewing experience both in-stadium and around the world.
Key competition format changes include:
- Two-Day Slam: The condensed format focuses all the action into one explosive weekend, ensuring non-stop excitement with no filler.
- Single Race Showdowns: The Men’s and Women’s Long Distance Race Groups will now compete in a single 3000m race, increasing drama and placing the full $50,000 prize on the line in one decisive battle.
- Ticket Refunds for Friday: Fans who purchased Friday-only tickets will receive automatic full refunds beginning May 16. Those with multi-day tickets that included Friday will get partial refunds. Questions? Email tickets@pobox.upenn.edu.
