4x4x48 Challenge - Florida

May 2nd 2025
Saint Petersburg, FL

Run 4 Miles Every 4 Hours for 48 Hours

The 4x4x48 is a race that tests mental strength and physical stamina. The objective is to run 4 miles every 4 hours for 48 hours. This may be done solo or as teams of 2 and 4.

The runs will go off at designated times every 4 hours, so the participants will have to plan for refueling, staying hydrated, recovering and resting within each 4 hour window. If the athletes are doing this as a team they will have to strategize the most effective way to accomplish this challenge.

Athletes may run or walk each segment as long as they accomplish this in the 4 hour window. We will also be offering a row/bike or ski option for those unable to run.

Prizes: $500 to fastest overall male and female
