Martin Pirongs, 51, created the “M25 Man” by tracking his 10-day, 180-mile walk.
The former TV actor from Brent Cross, covered 18 miles per day and stayed in Airbnbs or hotels.
He logged his steps with a phone and transferred the data to his website where the outline took shape.
He said: “Travelling through London, our feet are somewhere and our heads are somewhere else.
“We are very disembodied. So making something, a body, is a way of connecting.”
