800m sub-4 equivalent?

please clue me in, what am I seeing here?

1:48.70 and 4:00.00

::tips::

- the 2 times should represent concurrent ability. Times run more than a month apart may produce inaccurate results.

- this is still in beta stage, so accuracy may vary

100 0:11.95

200 0:23.02

400 0:49.65

800 1:48.7

1000 2:20.10

1500 3:41.73

1-mile 4:00.0

3000 8:03.51

2-mile 8:43.03

5000 14:15.68

10000 30:48.28

half-mara 70:15.24

marathon 150:25.77

The following are the equivalent of 3:59.99 for the mile from the credible sources:

IAAF Point Tables: 1:48.55

Purdy: 1:46.98

Schwartz (tinman): 1:48.8

McMillan: 1:48.0

AVERAGE: 1:48.08

Remember, equivalents are not predictions, they are simply performances of the same quality or value. Think of it more like $1 = X Euros. Whether someone can run an equivalent at a different distance depends on a ton of factors (training, genetics, competitive opportunities, weather, motivation, etc.)

Remove the ridiculous Purdy outlier. 1:46.98 is a joke that is more like 3:56.

Also equating the 800m and mile world record gives 1:48.54.

Equating the 800m and the stronger 1500m world record converted to the mile gives 1:48.86.

If you want to choose a nice figure to remember, the answer is 1:48.5.

1:48.0 is too fast, and 1:49 is too slow.

4:00 = 11.95? Yep, that's legit.

Well for comparison I coached one guy who ran 1:51, 3:41, 3:59, 7:57, 13:46. I coached another guy who ran 1:52, 3:38.5, 3:59, 7:47, 13:31. The 3:38.5 guy actually ran in the Olympics.

I know another guy who once ran 3:42 and his 400m PR was 55. I kid you not. He was a 5k/10k guy and made national teams in xc / track.

Bottom line - people are different with different strengths and skill sets. There is no "one size fits all" prediction. The job is to figure out the right formula for each person.

Just my 2 cents, but I believe 800m speed is over-rated for the 1500m / 3k folks. There's a big difference between speed-endurance and anaerobic-type speed.

Actually you are incorrect in specifics and in general principle.

Banister's 1:50.7 was following rounds, in a tactical race in 1950. He was

certainly capable of faster a few years after his 800 best.

Elliot was a 1:49 runner long before he was anywhere near 3:35

1500m.

According to one well know stat base All Time Athletics the 4:00 minute mile has been broken 4945 times (indoor and out) in sanctioned meets.

I'm guessing before May 6, 2016 we'll have 5,000.

This is a late reply (ok, very late), but what you're seeing is a calculator that calculates what a runner can run for all distances. It is not an equivalency calculator. As it says in the tips section, it will calculate what you can CONCURRENTLY run in ALL distances based on CONCURRENT abilities in TWO distances.

I'm assuming you're being sarcastic, and you think it's actually not legit? You're misunderstanding what the calculator does. It does not calculate equivalency. It calculates what a specific runner can run. If you want equivalencies, use something else like the IAAF tables I think?

It definitely depends on the runner and if they are more speed or strength based. Slagowski has 48.6 400 speed (first leg of 4x4), 1:48.70, and 4:08. He is a good balance of speed and strength in my opinion, but I don't think he will break 4 in HS.

A nine second improvement in less than a month for Slag.

Whoever said 1:48.5 is probably right as far as physical equivilant, though long ago 1:50> was like the promised land, I never came close.

Why not use Slag's open 400m time? My open 400m PR was 50.1, but I ran 48.3 relay split. Webb's PR was 49 flat and he ran 47 mid. Relay splits are not that accurate.

Maybe, but nothing you said proves they aren't accurate. It's possible that both you and Webb were just in better 400m shape on those relay days. Not enough information to know.

He ran 3:59:53 now lol
