Midwinter Marathon

Do you know what day December 21 is, Tomorrow? The winter solstice — the shortest day of the year. And this time it falls on a Sunday. How about a little challenge? Let’s call it Midwinter Marathon Madness. :)
It’s a marathon walking challenge where you design your own route and take care of everything yourself. The rule is simple: start at sunrise (or after), and finish at sunset. Technically, any distance counts as completion — but since “marathon” is in the name, the real goal is, of course, 42.195 km.
I didn’t invent this — the Sport Walk Squad launched the challenge, and I’m joining in.
I’ll probably wander around the Cseke Lake and Öreg Lake area in Tata: it’s close, there are public restrooms, open shops, and of course pastry shops — where I can celebrate the achievement with a few cakes… or soften the blow if I fail. :) Either way, it’s going to be fun!
If you’d like ChatGPT to plan your day, type this:
“On December 21, 2025, I’d like to walk a marathon distance in [city], [country]. I will start at sunrise and finish at sunset. Please give me the start and finish times, the slowest average pace in min/km I need to maintain to succeed, and how many kilometers I should have completed at each full hour.”
And then all that’s left to do is walk! :)
By the way, I did complete the distance:
