On the evening his life changed, Leigh Manley was running on a gym treadmill.
The Cardiff dad had always loved exercise. He ran two or three half-marathons a year. If he couldn't make it to the gym in his lunch break, he would find an hour in the evening.
One Saturday in October 2016, the then-39-year-old was on the treadmill at Newport Road's The Gym when he collapsed. He didn't realise it that evening, but he was about to endure more than three nightmarish years of ambulance rides, electric shocks and surgeries to his heart. At his lowest point, the former fitness enthusiast would struggle with a walk to the shops.
