Race Overview:

Welcome to The Rumble — The Fastest Race in Charleston

Get ready for a high-energy, elimination-style team relay race unlike anything Charleston has seen. Set in the heart of historic downtown at Hampton Park, The Rumble is a 3-stage, team relay packed with speed, strategy, and spectacle.

– In-race expo
– Killer swag bags
– Over $1,500 in cash prizes ($500 for each division winning team)

How The Rumble Works:
Each team consists of 2 runners. Together, you’ll compete in 3 rounds of 1-mile relay loops:

Runner 1 runs 1 mile → hands off to Runner 2 for 1 mile
– Your combined time = team’s time for the round
– After each round, the top 50% of teams advance one round closer to the grand prize (all teams run all 3 rounds, this pertains to the grand prize)

The final round (Round 3) determines grand prize division winners, age group champions, and other awards.

 
Divisions & Prizes:
Teams choose one of three divisions:

– Men’s
– Women’s
– Mixed

$500 to the winner of each division (Total Purse: $1,500)

Even if your team is eliminated from the grand prize before the final, you’re still eligible for:

Age Group Awards (based on total team age & 3-round time)
Fastest Mile Award (Individual & team)
