Looked at the splits for the main protagonists yesterday and re-checked today. By far the best 800m of the year, and very interesting reading, especially when the extra distance taken into consideration. N.B - the on-screen clock appears to be 0.1 slower than the official/stadium clock, so all splits have had 0.1 added to them)
Have to say that I also did some research on the track itself, which was resurfaced in 2010. On another thread I've compared the 1500 times for elites over past 5 years at Monaco compared to other tracks. Nothing conclusive except for whatever reason, the Monaco track is exceptionally fast for the middle distances.
1. A. Tuka 1:42.51 - 51.1/51.4 ~ 25.1, 26.0, 26.0 (1:17.1), 25.4
100m splits of: - 13.1, 12.0, 13.1, 12.9, 13.3, 12.7, 12.7, 12.7.
I estimate that he ran 2m wide on the last bend, which makes his run worth 1:42.26. He had about 150m of drafting (260 - 320m and 460 - 550m). Normally athletes expect 200m in total, so he lacked 50m, which = 0.08sec.
So overall his run was worth c. 1:42.1
Considering he's 24 and had a pb before this season of 1:46, then it's quite an unbelievable jump in ability!
In fact his yearly progression has been:-
2011(20) 1:51.09 Zenica (BIH) 01.06.2011
2012(21) 1:48.31 Helsinki (FIN) 27.06.2012
2013(22) 1:46.29 Tampere (FIN) 12.07.2013
2014(23) 1:46.12 Zürich (SUI) 15.08.2014
2015(24) 1:42.51 Monaco (MON)17.07.2015
2. N.Amos 1:42.66 - 50.5/52.1 ~ 24.1, 26.4, 25.8 (1:16.3), 26.3
100m splits of: - 12.6, 11.5, 13.2, 13.2, 13.0, 12.8, 13.1, 13.2
I estimate he ran about 1.5m wide on the 2nd bend (200-300m) and about 3.5m wide on the last bend. = 5m total.
This means it was worth 1:42.02 if he'd had the perfect race on the rails in lane 1. He got a lot of drafting, roughly from 200m to 550m. That's an extra 150m than is 'normal' for a fast paced race, which = 150/400 x 0.7 = 0.26
So overall his run was worth about 1:42.2.
3. A. Souleiman 1:42.97 - 50.4/52.5 ~ 24.8, 25.6, 25.9 (1:16.3), 26.6
Probably the most evenly distributed 200 splits of the competitors.
100m splits of: - 12.9, 11.9, 12.7, 12.9, 12.9, 13.0, 13.1, 13.5
I estimate he ran about 7.7m further than needed by running wide on the bends: - 2m wide on 2nd bend (200-300m), 2.5m wide on 3rd and 3.2m on last. That makes his run worth more like 1:41.99!
His re-calculated 200m splits taken extra distance into consideration are therefore ~ 24.8, 25.3 (50.1), 25.6 (1:15.7), 26.2 = 1:41.9
I estimate he had about 120m of drafting in total for the entire race, which means he lacked 80m of expected drafting. That's 80/400 x 0.7 = 0.14.
So overall his run was worth c. 1:41.8
It will be interesting to see if Souleiman decides to run the 800 as well as the 1500 in Beijing, because he has a good chance of medaling in both. Perhaps that will entail too many races to be at a peak for his favoured 1500!?
4. B. Berian 1:43.34 - 50.6/52.7 ~ 24.1, 26.5, 26.0 (1:16.6), 26.7
100m splits of: - 12.2, 11.9, 13.4, 13.1, 13.0, 13.0, 13.4, 13.3.
I estimate he ran 2m wide on the 3rd bend, but got his fair share of drafting.
Run worth 1:43.1.
