required 100m/200m/400m times to run 1:50 for 800m

100m

14x4= 56

56x2=1:52

50 second 400M speed is sufficent.

If you want to run under 1.50 you should not worry about your 100 and 200m speed.

400m speed is a lot more important.

Sub 50 would probably be the minimum but that would mean you would need a huge amount of endurance.

If you had little endurance (1500m speed) you would need better 400m speed eg 46-47 secondes.

I am not that sure though.

Don't overlook the overdistance aspect. Something around 3:55 for the 1500 and a 4:10 mile. Don't look too much into the numbers though.

when in 800 shape: 800 time = 2x(current 400m +4-8sec) works for most well trained runners. 4 secs will be for endurance trained guys. 8 for speed based guys. Of course the speed training will allow those guys to run a second or two faster for 400m so either approach works ok. Pick which one works best for you.

Just my opinion...

100m - 11.03

200m - 22.26

400m - 49.06

800m - 1:50.0

Those numbers were calculated from a fly 30, which would determine max velocity at 9.8 m/s or 3.06 for a fly 30 test.

This is the speed component, and of course there are exceptions to any rule, so I am certain athletes have run 1:50 without being 11.03 100m runners. It's just one formula.

as opposed to just running a 60-50 race?

I could see a 1:50high runner with a lot of endurance and a bad start only going

13/25/52. THey would have to have a perfect race and split it 55/55 though. More likely for a 1:50 guy is 12/24/50, and even then they would need a fair amount of endurance. Most 800 guys rarely run the 200, let alone the 100...

100m and 200m are more about accelerating from a block start and hitting top speed. The 800 isn't as much about speed as it is about endurance at speed. Sub-50 400 top end speed is sufficient, but what is most valuable is the ability to shift into that gear off a slower 800 pace multiple times during the race in order to respond immediately to the do-or-die tactical nature of the race. Physiologically master the repeatable 400 meter speed, and psychologically master the 'sprint-float-sprint' tactic, and you will have the rudimentary tools to compete with 1:50 800 runners.

When Dave Wottle ran the 1972 Olympics, every split of his was a 26, so 26-28 speed is all you really need.

My pr is 1:50.77, 400 pr is 48.5, 200 I have no idea but could run mid 23 in practice. I would be in the middle between speed and endurance, I could run a 2:59 1200 anyways...

there you have it

Huh?

By that logic, Usain Bolt should run 1:17 for the 800.

Yes, and by the logic of his 19.30 he can run a 39 400M.

And Jeremy Wariner can run a 1:90

Not sure where you got your logic from but all Wottle Ran was 26 4 times coming in at 1:44.

Ran 1:50 high PB, and plenty of low- 1:51s

My 200m was 22.8 in practice, 48.4 for 4 x4 relay, 49.13 flat, 1:19-mid 600m, 2:59 1200m

23.8

50.5

I don't think that's the best formula. I'm an 800m runner and my 400 PR is 49 point. Using that formula my 800 would be between 1:43 and 1:47. My PR is 1:52. It's not close with any of my teamates 400/800 PRs either, and they range from 1:48-1:53.

I have never ran a even split so you dont need to worry about the spilts. You need to get on the track and just lay it out there. Go out fast and keep it up!!!

If you are primarily an endurance trained runner, so you are running 30+ miles per week and you have equivalent 1500/1600 times, you would need to run 50 for 400 or faster. Beased on hand times, the overall results would be roughly:

400 = 50.0

200 = 23.0 (400 ~ 2X200 + 4 sec)

100 = 11.5

Now this is hand timed, so it comes to 11.2x electronic.

For sprinters, or 400/800 types, which is more what I coach, the sprint times have to be faster. A sprinter gives up 15-17% of his 400 speed going to 800 (an endurance trained runner gives up about 10%), but the sprinter has perhaps better speed endurance between 200 and 400 because he's working on it more, so:

400 = 47

200 = 21.8

100 = 10.9

100 electronic = 10.7x

even with 26-27-28-29 its still 1:50

don't know about 100m or 200m but my 800m pr is 1:50.32 and my 400 time is 50.5
