True horsepower?

wouldn't want to try the mile anymore but I ran the 6 minute mile every September for gym class in High school and the 200 meters in less than 30 seconds thats and 1/8th mile pretty sure I could pull off a 2 minute quarter , maybe 2.5 thats still 150 seconds lol .
They used to give us a 100% for the term if we could do 1.5 miles in under 9 minutes but that last 1/2 mile got me every time best was 9.03 .
