Islamabad Run with Us (IRU) introduced the 24/48-Hour Endurance Run Challenge as an ultimate test to extreme endurance and mental strength. Inspired by the ethos of David Goggins, a former Navy SEAL and ultra-endurance athlete, this challenge pushes participants to their physical and mental limits.

Participants in this challenge embark on a remarkable journey, running a constant distance of 4, 7, or 10 KMs at intervals of every 4 hours over the span of 24 or 48 hours, within the designated time frame.

Initially introduced in March 2021, the 24/48 HR Endurance Run Challenge garnered nationwide participation, drawing over 100 dedicated runners. Since its inception, it has evolved into an annual cornerstone event for Islamabad Run with Us. Following the successful runs in October 2022 and most recently in October 2023, this challenge continues to attract passionate athletes seeking to push their boundaries and celebrate the pursuit of relentless determination. Join us in this ultimate test of endurance and mental determination!
