Phil Drummond spent up to eight hours a day on the asphalt to complete his gas guzzling 3,343 mile odyssey.
Averaging 279 miles a day, the tarmac fiend survived on fizzy drinks and boiled sweets as he careered around Britain.
Sharing a map of the “dull” route on Facebook, the 48-year-old said: “I avoided motorways almost entirely.
“It was just me, my trusty little green car, a crate of sugar-free carbonated beverage, a few bags of boiled sweets and a separate playlist for each day.”
Phil started and ended the trip in his home town of Poole, Dorset, last summer.
Travelling west, he ticked off Land’s End before heading north through Wales, Liverpool, Glasgow and around the top of Scotland.
After reaching John O’Groats he bombed through the Cairngorms and past Newcastle before weaving through London and the Kent coast.
His trip took in Dunnet Head in Caithness, Lizard Point in Cornwall and Ness Point in Suffolk, the UK’s most northerly, southerly and easterly points respectively.
Despite vowing to avoid motorways he broke the rule on stretches of M1, M6, M8, M20, M48, M53, M62 and M90.
The post, shared on Dull Men’s Club UK, garnered over 53,000 likes and sparked a wave of responses.
One chimed: “Try it in an electric car next time!”
While one quipped “Lincolnshire not good enough for you then?”, after noticing a massive detour Phil took to avoid the county.
Others were more critical of his relentless driving schedule, adding: “Did you actually want to visit anywhere, or just drive for 12 days solid, which is pretty dull.”
Another suggested it was a “shame” Phil didn’t have any time to enjoy the places he travelled through while another said it was too much driving.
Someone added: “How much did it cost in fuel?”
It is unclear how much Phil spent on petrol during his trip.
