So I found this interesting figure the other day in my Runners’ World Magazine.

It says that a 150 lb. person receives 110 TONS of impact to their legs EVERY MILE.
So I set up my quick little equation to find out what it is for a 220 lb. person (220×110 = 150x; There’s my Algebra 1 coming in use! I knew it would.).

That equals 161 tons. So every mile I run, my legs are receiving 161 tons of impact. Man…

So the last two weeks I have run some 10-milers. A ten mile run equals 1613 TONS OF IMPACT.

And just to go one step further… every 10-mile run results in 3,226,667 lbs. of impact to my legs.

That explains why I’m on a morphine drip for three days after those runs.
