He has just flown from London to Sydney in a microlight aircraft no bigger than a bath tub in 55 days.
This follows strolls up Mount Blanc, Mount Kilimanjaro and the Himalayas, a quick trip round the Malaysian Grand Prix circuit in record time, racing hundreds of miles across deserts in China, California, Qatar and the Sahara in temperatures of up to 200 degrees, circumnavigating the globe in 80 different forms of transport and hauling a sledge across 250 miles of Antarctica to reach the South Pole.
He's also blind.
Since a triumphant flight into Sydney over the harbour a little more than a fortnight ago Miles, of Ferrers Crescent, Duffield, has conducted 204 interviews, and number 205 with Japanese national radio followed soon after the Belper News left. He has spoken at conferences in Portugal, the Phillipines, Hong Kong, South Korea and Manchester while also trying to reply to the 700 e-mails he receives on a daily basis.
It wasn't always like this for Miles, who went blind aged 30 through a hereditary condition that also affected his brother Geoffrey and now tours the world giving motivational speeches.
Miles said: "I did nothing until I was 50 and I'm only 58 now. I saw being blind as a handicap but when I was 50 my brother sailed from South Africa to Australia single handedly in 53 days, he got trapped in a force ten gale and almost drowned, but he got there.
"He told me the lack of sight wasn't a problem, my attitude was. He's a real roll model to me."
Miles grew up in Zimbabwe dreaming of following his father Jack into the air force but failed the eyesight tests at 18 and found out about his impending blindness at 21.
Aircraft controls that speak to the pilot rather than displaying readings on a dial have now enabled Miles to fulfil his dream after all.
He said: "The controls work like a satellite navigation system you may have in your car. My co-pilot gave me the grid references and the computer directed me there through my headphones.
"It was very tiring, my head would get so fuzzy with numerous commands coming in and I had to concentrate all the time, for five hours or more at a time. Sometimes I had to lift the visor on my helmet to get a blast of cold air and wake me up and I did actually fall asleep three times while I was flying."
It's not just a case of plugging the coordinates in and letting the micro light fly itself of course, and on his epic journey Miles and his sighted co pilots Brian Milton and Richard Meredith-Hardy encountered circumstances that would test even the most experienced of sighted pilots in the most modern and well equipped aircraft.
Miles said: "We flew into a storm between Cyprus and Jordan. There was a layer of cloud below us and a layer above and as it closed in the temperature dipped to minus 25 degrees.
"All the moisture immediately turned to ice. My whole flight suit, the microlight, the wings everything was covered in thick ice. I could feel solid blocks of ice through my gloves.
"The crazy air traffic controller in Lebanon kept telling us to climb and then asking us to identify ourselves because on his screen we looked like a jet and yet we were travelling so slowly. I'm sure they would have grounded us if they'd known we were only a microlight.
"We also got caught in a tropical storm at Kuala Lumpur, we flew into a valley at 200 feet but the lightening was just forcing us lower and lower. The rain was so heavy it was like flying through a waterfall and the computer packed in.
"Richard said he could only see 30 yards ahead, he couldn't see the sea below us even though the alarms were going off about us being too low. Richard was peering out over the sides looking for the sea or anything and he eventually caught site of the beach.
"We decided to follow the beach and that was going fine until suddenly it disappeared and a sheer rock peninsula was right ahead of us. We had to bank away at a 90 degree angle or we'd have flown straight into it.
"I've found it's better to be on the ground wishing you were in the air than in the air wishing you were on the ground."
It almost makes landing at international airports in between two Boeing 747s that could annihilate the microlight if they flew too close seem like an everyday task.
The reason Miles pushes himself like this is to raise money to help other people around the world who suffer from blindness through www.seingisbelieving.org.uk
Miles said: "There are 37 million blind people in the world, 28 million of them could see tomorrow if they had the money. Just £30 would pay for a child to have their cataracts removed.
"We started our flight two days late because the original co-pilot had to drop out at the last minute and that meant I wasn't going to make it to a fundraising dinner we had arranged for later in the
trip.
"They said I could fly on to the dinner and Richard and Brian the co-pilots would bring the microlight on behind me. That meant I wouldn't complete the entire journey myself, I wouldn't fulfil the dream.
"I worried about it all night and then suddenly I thought what a stupid proud idiot I am. Who cares if I'm not in the record books? The big thing was the money we raised at that dinner gave some children their sight back.
"Vision without compassion is a bad thing."
Miles says he has never been as content in his life as he is now with his wife Stephanie and three children. He does have his eyes on another challenge though – flying at the speed of sound. Just an ordinary guy?
