Running is obviously a very healthy form of physical activity. It improves your cardiovascular fitness, burns calories and can even benefit your mental wellbeing.
But it turns out that running is also a productive activity for reasons totally unrelated to your overall health.
Indeed, one avid runner by the name of Lenny Maughan has been turning his routes into pieces of art over the past four years.
The San Franciscan uses a fitness app called Strava to help him create his striking artworks by planning his route so that it resembles a real-life image.
"You can’t see the lines drawn until after you finish your run," Lenny told SFGATE. "So it’s such a joyful feeling when you put in all of that work and you finally finish and get to see what you envisioned at the end."
"San Francisco is my canvas. I use the streets as a framework for what I want to do, find shapes, and make it work. Kind of like how little kids look up at the clouds."
One of the most elaborate pieces of 'running art' Lenny created was his Frida Kahlo masterpiece.
In real life, the route was a staggering 29 miles and took him six hours to complete.
It was, in fact, Lenny's most recent piece of running art and also the one which has thus far received the most attention.
When it was posted on Reddit by a friend of the unique artist earlier this week, it took the forum site by storm.
"Beautiful, but my calves/knees/bones hurt just thinking about running that," one Redditor wrote in response.
"Running art?! I can’t even run for fun lol this is so cool And very original," added another.
"Very neat! Is 'running art' a new trending activity I don't know about?" a third user asked.
So far, Lenny has made 53 of his spectacular works - here's hoping there's many more to come!
