The Aberdeenshire man took first place in the Isolation Ultra, organised by Cockbain Events, recording a distance of 180.2 miles, on a 50 metre course within the confines of his back garden.

What makes Mike's performance even more remarkable is that he completed the epic run towards the end of the April-long window after setting out a 106 mile marker earlier in the month. AND he had undergone open heart surgery earlier in the year.

The IT specialist at the University of Aberdeen had the benefit of a scenic, if tight, course, with views across the North Sea from the garden of his family home near Collieston. He was also supported by wife Annette and young daughter Flora.

But Mike didn't have a classic preparation for this serious ultra challenge as he had undergone surgery to correct an anomalous right coronary artery on 25 February. This followed concerns Mike had last year when he noticed that he was finding it hard to breathe while running uphill. This difficulty became more pronounced and Mike sought medical advice.

He describes the diagnosis: "I was born with my right artery growing out of the wrong place.” The upshot was an operation at Glasgow Golden Jubilee Hospital.

Mike told runABC Scotland online: "I was out of hospital after just three days. The nurses on the ward were not sure about discharging me so early as they had never let anyone out in less than four days – the preference is seven. However, I passed all their fitness tests and the surgeon said it was ok for me to go.”

After just 10 days, Mike went for a slow two-mile run with his wife Annette keeping an eye on him.

“Every time I went out, I felt I had to hold my chest. The rehab physiotherapist told me this was due to the impact and that my chest bones had not fused together properly, so I started doing a lot of cycling instead to get to get my fitness back."

Mike had only started running properly again when he decided to make the Isolation Ultra attempt. He said: "I relied on muscle memory and stubbornness to get me through the challenge. The run was slow. Stopping so often to turn around was like doing a bleep test for 27 hours.”

Event conditions required a maximum loop of 100 metres at your home and a non-stop (not staged) run with a 1 hour maximum rest stop.

Event organiser Mark Cockbain was effusive about Mike Raffan's double ultra effort: "Only a few weeks after heart surgery, he came back for a second attempt smashing out 180.2 miles to become the Isolation Ultra ‘Cooler King’."

A major inspiration for the 'convalescing' Raffan's superhuman effort was to thank the medical team at the Golden Jubilee Hospital and he has already raised over £2,000 via his page at JustGiving.
