He decided to attempt the feat while recovering from an ACL injury suffered in Naval Special Warfare Preparatory School portion of the Navy SEALs training pipeline. The 24-hour pull-up record at the time of McCastle's first attempt was 4,030. After he had completed around 2,300, McCastle suffered muscle tears in his forearms and biceps as well as rhabdomyolysis. He managed to finish 3,202 pull-ups in 19 hours before quitting due to injury. He spent two days in the hospital recovering.

His next feat took place in December 2014 and involved flipping a 250-pound truck tire 13 miles, attempting the feat one day after he lost his father. The initial plan was for McCastle to flip the tire along a 13-mile stretch of road where he was stationed Oak Harbor, Washington. He could not secure the requisite municipal permits for the journey and ended up flipping the tire in a parking lot. The stretch of pavement was 500 feet, and McCastle flipped the tire across that stretch 137 times to equal 13 miles . The feat took around 10 hours to complete.

McCastle's goal was to raise $20,000 for the Michael J. Fox Foundation for Parkinson's Research. McCastle had lost his father to Parkinson's a few months earlier . Prior to the rope climb, McCastle also completed a 50k run for cancer research. In September 2015, McCastle announced that he would be attempting the 24-hour pull-up record again. During this attempt, McCastle wore a 30-pound pack on his back to represent the burden of wounded soldiers. This feat was performed to raise funds and awareness for Operation Enduring Warrior, a charity and advocacy group for wounded soldiers.
