"The idea came from a couple of similar runs I did two years ago for a competition," Delaney said, when reached by email on Thursday. "I thought I'd do the Rudolph one a couple of weeks ago for fun, my friends seemed to like it, so I did the Santa one the next day. It's just escalated since and had loads of attention, so I feel I can't stop now!"
Delaney has already run more than 30 miles to create the designs, according to the distance total on the 10 examples he provided (shown below). Believe it or not, planning the perfect route to achieve the designs actually doesn't take that long, thanks to the app.
"Plotting the most suitable routes probably takes 10-15 minutes each," he said. "Maybe a few hours planning in all. They haven't all come out perfectly, the planned route maps that I follow in the Strava app are much tidier than the actual maps of where I've run, but it's close enough. I haven't yet gone wrong enough on one to have to start over, but still have a few days left to go, so there's time!"
