John McDonnell’s story is one of extraordinary resilience, from overweight and unfulfilled, through a life-threatening stroke and heart surgery, to running a sub-three-hour marathon at 55. Told in full in his debut memoir A Heart for Running: How Running Saved My Life, his story proves that running didn’t just transform his body, it saved his life. Whether speaking to corporate teams, sports organisations, schools, or public audiences, John brings a rare authenticity that few speakers can match, a story of ordinary determination producing extraordinary results. If you want a speaker who will leave your audience genuinely moved and ready to take action, John delivers exactly that.
