How long does it take to walk 100km?

Okay, so you're wondering how long it takes to walk 100km, huh? That's a big question!

Well, roughly speaking, walking 100km is gonna take you around 24 hours. Yeah, that's a whole day! I remember when I first heard about these crazy 100km hiking events, like the Mammutmarsch – they're intense! It's not about running, mind you; it's straight-up hiking, and you gotta finish within that 24-hour window. Could I do that? I honestly don't know!

From what I've seen, the average walking speed during these things hovers around 4.12 km/h. But, hey, that's just an average, right? Your time could be faster, or maybe a little slower. It really depends on you. Are you a seasoned hiker? Do you have the right shoes (believe me, that makes a HUGE difference!)? How about your fitness level? Plus, are we talking flat ground or mountains? So many things can affect it, you know?

I remember this one time I tried to hike even a fraction of that distance – maybe 20km? – without properly breaking in my boots. Big mistake! Blisters the size of coins! Lesson learned: preparation is key, people! So yeah, 24 hours is a good benchmark, but don't take it as gospel. Listen to your body, and happy trails!
