Sorry I made a mistake. That approximation was truncated, not rounded. That doubly upsets me, because I hate it when people truncate rather than round. Sorry to have put anyone through that torment.

That's the world record marathon speed. Yes, it has now dipped under 70 seconds per lap.

I appreciate this awful bumper sticker humor you have in this post hahahaha
This thread: Another reason LRC is awesome.
I could only stick with him for four laps. D*mn.

No rounding errors yet.
Sorry, that's not exact.
Sorry for you, but yes it is.I did find another huge error though -- I'll leave it as an exercise for the interested reader.

I hate to disagree with you rekrunner, but you don't use the imperial measure (26m385y) and convert it to metric. Metric is the official marathon measure. The nominal marathon distance according to the IAAF is 42.195 km. (plus the short course prevention addon)

Isn't the "exact" marathon distance 26 miles 385 yds?
In other words, exactly 26.21875 miles?
No the exact marathon distance isn't expressed in imperial measure.

The popular metric approximation of 42.195 km is exactly 12mm too long.
42.195km isn't a metric approximation, it IS the definition of the marathon distance by the IAAF for almost 100 years.

which is that 12 thousands of a meter is not more than 7 thousandths of a mile. maybe this time the mods will not be offended.

It's called INSANE. 4:41 pace for 26.2 miles. I can't fathom, but then again, I'm just a hobby jogger.
Did it. Out of shape. Suffered for 400m. Mind boggled. Now I need to get the fat asses from work to try
Only 105.4 laps of a 400m track averaging sub 70. Simple decision. I'm going to grad school instead. Better return on investment
I just ran that pace for 1609.34 meters. HR around 130 bpm. Once I get healthy I'll try it for the marathon distance.

Agree. Point well made!
The ppl trying to do the math and dissecting pace here are obviously compensating for lack of talent. Go back to your 20 minute turkey trot goal race. See you there.

First you should try running a full mile. 4 millimetres (0.0000024854847689493358784697367374533 miles) is a long way to go if you're tired.
I think that the iaaf officially changed the distance to be equal to 42.195 km.
I actually didn't know that the official marathon distance was metric - 42.195 km.
I keep learning here.
And the short course prevention add on adds 42 m.
So they really ran 42.237 m.
Do they have an official metric distance for the mile?
Do they run 1609.35 meters, which is slightly longer than a mile since 1609.34 m is slightly less than a mile?

Correct. 4:41/mile equates to 69.9 for 400m.
Dang-- we used to do mile repeats at that pace. They were some of the ____ hardest workouts. Absolutely hated them.
Thank you for making me feel humble yet again.
He can easily drop 26 seconds off his time. All he needs to do is run 1 sec per mile faster. See how easy?
