The History of the T-Shirt Marathon Record
David Rush first set the record in 2019, when he completed a race wearing 111 T-shirts. It was a fun, unusual, and physically exhausting performance that gained global media attention.
However, a few years later, another athlete broke his record by completing a similar race wearing 127 T-shirts. Losing the title motivated Rush to prepare for a comeback.
His previous attempt before the latest race was during the Idaho Potato Half Marathon, where he attempted to beat the new record but was only able to wear 114 T-shirts before health concerns forced him to stop. The excessive pressure around his neck restricted blood flow, making it unsafe to continue.
But he refused to give up.
The Challenge of Wearing 137 T-Shirts — Why It’s So Difficult
Wearing one or two T-shirts feels normal, but wearing 137 layers turns into a major physical challenge. Runners experience:
1. Extreme Weight
The combined weight of dozens of shirts can exceed 20–30 kilograms, making running extremely tough.
2. Restricted Movement
Each additional shirt tightens movement in the arms, chest, and shoulders.
3. Difficulty Breathing
Layers pressing on the chest can make breathing challenging during long-distance running.
4. Blood Circulation Pressure
Shirts around the neck create pressure that can restrict blood flow — which is what happened to Rush in his earlier attempt.
5. Heat Build-Up
Wearing so many layers traps heat, pushing the body into overheating.
6. Balance Issues
The bulk of clothing affects running posture and balance.
Completing a half marathon under these conditions is a massive endurance challenge.
Training: How David Rush Prepared for the Record
Determined to reclaim his title, Rush trained for months. His preparation included:
1. Running With Heavy Clothing
He practiced running while wearing multiple layers to simulate the pressure and weight.
2. Weighted Backpack Training
He carried heavy bags during runs to prepare his muscles for extra load.
3. Cardiovascular Conditioning
He performed long-distance runs to build stamina.
4. Mental Toughness Training
Knowing the discomfort involved, he trained his mind alongside his body.
5. Careful Health Monitoring
Rush monitored circulation, breathing, and hydration closely.
His training plan focused not only on physical strength but on avoiding the complications he faced during previous attempts.
