Paddy completed it in around 20 hours 35 minutes, comfortably smashing the previous record by more than three hours.
On the list were: 1,250 press ups, a two-mile swim, a 12 mile march, 3,250 sit ups, 1,250 hip flexors, a 110 mile cycle and a 20 mile row.
Added to that was a 20 mile elliptical walk, 1,250 star jumps, weight lifting, a 12 mile run, 5km on the stepper machine and as many burpees and squat thrusts as possible in five minutes.
He also completed a one-mile treadmill run, carrying a 44lb backpack.
In preparation Doyle trained in New York, at the famous Gleason's boxing gym, where he was pushed to the limit by professional boxer Troy Blackmore. He also received coaching from instructors at Virgin Active.
Gemma Woodfield, spokeswoman for Virgin Active said: "Paddy well and truly smashed the record. He picked up speed through the night, as at 6pm he was on target but not ahead of schedule. He had a great deal of support from the gym members who spurred him on and his four month training with the staff at Virgin Active certainly paid off."
