'19 Paris DL

was already qualified for the Final, so no crushing urgency to do so I suspect.

from the November '10 T&FN:

Since Tom Hampson of Britain ran history’s first sub-1:50 in the 800 at the ’32 Olympics, only twice in the progression of the fastest time ever—not necessarily the official World Record—has the mark been made with a second lap faster than the first. Those were by Jim Ryun and Dave Wottle.

On average, these 22 races were run with a second lap that was 1.7 seconds slower than the first.

Going backwards, here’s the best-time progression, with lap splits and differential (+ = converted from 880-yard time):

1:41.01 David Rudisha 48.9/52.1 +3.2
1:41.09 —Rudisha 49.1/52.0 +2.9
1:41.11 Wilson Kipketer 49.3/51.8 +2.5
1:41.24 —Kipketer 48.3/52.9 +4.6
1:41.73 —Kipketer 49.6/52.1 +2.5
1:41.73 Seb Coe 49.7/52.0 +2.3
1:42.33 —Coe 50.6/51.7 +1.1
1:43.44 Alberto Juantorena 51.4/52.0 +0.6
1:43.50 —Juantorena 50.9/52.6 +1.7
1:43.5+ Rick Wohlhuter 50.7/52.8 +2.1
1:43.7 Marcello Fiasconaro 51.2/52.5 +1.3
1:44.0+ —Wohlhuter 51.7/52.3 +0.6
1:44.3 Dave Wottle 52.9/51.4 -1.5
1:44.40 Ralph Doubell 51.2/53.2 +2.0
1:44.3+ Jim Ryun 53.0/51.3 -1.7
1:44.3 Peter Snell 50.6/53.7 +2.9
1:45.7 Roger Moens 52.6/53.3 +0.7
1:46.6 Rudolf Harbig 52.8/53.8 +1.0
1:48.4 Sydney Wooderson 52.3/56.1 +3.8
1:49.0+ Elroy Robinson 53.2/55.8 +2.6
1:49.1 Ben Eastman 53.7/55.4 +1.7
1:49.8 Tom Hampson 54.8/54.9 +0.1

Fascinating! What do we make of this? Ryun and Wottle both ran 1:44.3 decades ago. Is this the fastest an 800 can be run w/negative split? What if Rudisha in London went out 50.5? Could he have come home 50.4?

Love this kind of thought experiment/debate. Why are the 400 and 800 the only distances where the WR isn't regularly run with negative splits?

What I'd make of it is this - for a top flight long sprinter to run their best 800, they shouldn't leave more than 2 seconds between lap times.

Rudisha ran 51.9 approx/51.4 for 1:43.35 in Hungary in 2017. I'm pretty sure that first 400 split is correct give or take 0.1s - Rudisha was 1.0s behind the pacemaker a second before the bell.

I always find it frustrating that the live results are so far ahead of the NBC stream (about 40 seconds in the shot at this point)

As opposed to vhs quality 12-24 hours after the results for '60s Olympics? I think we have been spoiled by modern technology.

All 'live' coverage, whether TV or internet, is always behind real life. Sometimes by just a few seconds, sometimes by as much as a minute. That's what I found out by following live internet results and live coverage simultaneously.

Also, a 51.59/51.25 for 1:42.84 at the 2010 African Championships.

After watching Sawe jump a few times this season, I wonder just how much higher he could go if he bent his back more at the apex of his jump. It appears to me that he is losing 2-3 inches on his jump. Has anyone else noticed that?

When most of the top athletes have run their best they have done so with positive splits (same as 400m) and of course there are many examples of this as already provided.

I'm no technician, but to me he certainly seems like a diamond in the rough.
