https://dqydj.com/income-percentile-calculator/I've seen different income percentile calculators but this one has 257,000 as the 98th percentile for income for all workers.
https://runrepeat.com/how-do-you-masure-up-the-runners-percentile-calculatorThis may not be that reputable of a website but it has 15:30 for a 5k as 99.5th percentile for men in their 20's. As age goes up the percentage of men that can run a 15:30 will undoubtedly go down.
Just multiplying these two variables (simplistic, yes, since a lot of runners are high earners and there's likely some correlation between type A runners and high income) and you get 1/50 * 1/200. That's 1 in 10,000 runners in their 20's will have income of 257,000 or more and also a 5K of 15:30.
There are plenty of folks making more than physicians but the percentage of people making more than physicians is quite low. You're talking most professional athletes, movie stars, big wig law, high end software engineers (most SWE won't be making 250k+), some finance bros, some small business owners, some CEO's. It's just not that common.
It's not that easy to make 250k or more a year unless you have family connections, are brilliant and hard-working (some tech workers), or grind it out and study careers which are usually high paid like medicine. The debt sucks though.
Add the attractive wife variable: a15:30 5k guy making 250k+ wife a wife more attractive than let's say 80% of women and it's getting super unlikely to see all these in one person at *one* time.
My med school had a lot of people, like 150-200 in my class. There were some runners but the fastest was 1640-1700.
My running club which was fairly fast and comparable to some low-end D3 colleges had one future doc who ran the equivalent of 16:00. Alas, he was the fastest one.
In summary, it's a very low percentage of people that can run 15:30, make 250k+ and especially at the same time. A lot people making good money are in their 30's and 40's and they can't run 15:30 anymore.
