Paul sits down with Mark, introduced through fellow guest Rebecca after a 25-year friendship forged in their first graduate jobs. Mark's running story starts like so many others on this podcast — nearly 30, a neighbour training after childbirth, and a Sunday-night routine that began with not being able to run to the end of the road without stopping. What follows is a conversation about weight, discipline, and the slow work of learning that fitness isn't just about miles logged but what you actually put into your body — portion control, tracking, and finally understanding his own relationship with food after decades of "treadmill specials" and Christmas-to-Lent cycles.

The heart of the episode is Mark's 2019 challenge: 15 marathons in 15 months, run while working for Sands, a charity supporting families after stillbirth and neonatal death, raising money and awareness one marathon at a time. Inspired by local hero Francis Benali, Mark ran through COVID lockdowns, homemade courses, and socially distanced club laps, eventually smashing his sub-four-hour goal at marathon 13 with a 3:52. Then came marathon 14 — run the week before Christmas, six days after his PB, tracing his own life story from the hospital where he was born to the streets of his childhood. He finished feeling wrong. By that night, his wife and friends were insisting something wasn't right.

What followed was a trip to A&E against COVID-era advice not to go, a blood test showing a troponin level thousands of times above normal, and the discovery that Mark had run his 13th and 14th marathons — including a PB — while having a heart attack. His cardiologist's verdict reframed the entire story: rather than reckless, Mark's fitness had likely kept him alive long enough to get help. The conversation doesn't stop at the medical drama, though — it goes deep into what came after: the identity crisis of no longer being "marathon man," survivor's guilt, counselling, and the slow rebuild of trust in his own body.

Six years on, Mark is back running 10Ks and half marathons, has never ruled out a 15th marathon, and carries with him a line spotted on a stranger's race shirt at a parkrun: the comeback is greater than the setback.

Honest, moving, and full of hard-won perspective — this episode is about fitness, faith, identity, and what it really means to be lucky to be alive.
