Mark joined me to chat through his running journey, going from a guy who ran in big hoodies in the dark for 10 minutes to tackling an 145 mile race along the Grand Union Canal.
He's part of the 100 marathon club, ran multiple ultras and likes to see how far he challenge and test his body.
We spoke about nutrition and how to prepare for long distance races and also how we then wrote his own book documenting the various challenges he's set himself.
A great chat even though he got attacked slightly by one of my cats Lily.
