you will look cooler walking, everything else is irrelevant

There's a lot of complications to this problem. You assume that rain falls directly down, but most rain is accompanied by wind. Now, rain hitting you side is a function of time, distance, and speed (if you exactly match the speed of the wind, no rain will hit you from the side). Turns out, the best strategy into the wind is maximize speed, and with the wind you want to be a bit faster than the wind.

I've honestly wondered about this my whole life, but couldn't figure out the maths behind it. Moving upward into the rain is a great visual.

Never thought I'd use: "Wetness per second," as a measuring unit.

This is amazing, Iāve had this exact theory for ages now, but always felt like I was making stuff up when I was telling other people. Until today. Seeing it actually be proven true feels so validating.

Reality math is always cool, but you should consider adding the angle of the raindrops to your equation. They almost never fall straight down. Just a slight wind from different angles could change the equation a lot.

That was the longest "running is better" I've ever heard

I remember in secondary school the bell rang and i had to take the bus home, but the bus stop was a short walk away, 5 minutes or so. It started literally pouring buckets. I decided to take that walk very slowly, since my bus was gonna be late anyways. It was like i jumped in a pool. When the bus eventually came, water was forming a small puddle at my shoes. It was actually an amazing experience. I need to do this again sometime.

i think there's another factor that isn't mentioned here. when you stand still, your average cross sectional area (where raindrops will hit you from the top) is the minimum. but when you run, you lean forward, which increases your cross sectional area and expose your back and legs to rain too.
to minimise rain, you should therefore try to run while remaining as upright as possible. however, this limits your top speed because it's harder to balance. so it's not immediately obvious how fast you should run.
practically, i think maintaining balance (so you don't slip and fall), uprightness (to minimise vertical rain), and speed (to minimise time spent in the rain) would be the most effective. lean a little forward while still running at a good pace AND try not to slip.

But if you run you'll trip on wet ground and snap your neck, therefore I conclude the best way to get from point A to point B is to stand still.

Thank you for answering this question I've pondered for so long!

I rmb watching this 10 years ago, now it popped up again wow

I've got a factor that he didn't mention

So basically... Run sideways

I have watched this video soo many times over the years and every time yt algorithm recommends it on my feed i wonder what the conclusion at the end of the vid was, so I watch it again every time i see it...

You have no idea how much I needed this answer. Everytime it rained, this was the question in my head, well my answer was also the same as the amount of water landing on my head per second would be equal no matter how fast I am going, decreasing the time will decrease amount of water..

Nah mate, I'll just use my extreme reflexes to dodge the rain . Take my advice...
