What a way to finish a gruelling week. My fastest time and all the more special, given an epic longer than planned trek of 29 miles up the Thames the day before, not the ideal preparation for a marathon race today. But all my training came together when it mattered.

Colonel Simon Chapman

Personal military fitness training and Royal Marines ethos got him through the gruelling challenge.

He said: “Being a Marine certainly helps with the mental and physical extremes. I’ve been training since September last year and I’ve needed to draw on some of my military training to help me get through the wettest winter for years.

"I’ve seen Dartmoor, where I train, at its worst, particularly during the snow in March.

“In some ways running the actual challenge is easier - most of the ground is new to me (rather than the monotony of running the same old training routes) and the landscape and some of the views in Devon and Dorset have been glorious. People I’ve passed on the way have been very supportive.’’

Si trained over 30 weeks, building up the distances and the intensity.

From Christmas onwards he sustained 60-70 miles/week, regularly completing 20+ miles training runs and culminating with 10 half marathons over 10 days at the end of March.
