It's hard to not ask that question after looking at splits from last night's Ethiopian 10,000 Trials:
Hagos Gebrhiwet's close was pretty good.
I went back and timed the final 1600 of the men's race via Jeroen Deen's Facebook stream.
Here is what I came up with:
Final 1600 of 4:05.9
Final 800 of 1:57.1
Final 4oo of 54.6
(Leader-to-leader, I had the splits at 64.3, 64.6, 62.5, 54.6. Gebrhiwet didn't get the lead until after the last lap started. I'd estimate his final 800 was 1:56.8, and last lap was 54.4)
Is that any good?
At the 10,000 at the 2017 Worlds, Mo Farah closed a 26:49.51 race in 55.63 -- at least a full second slower than what Gebrhiwet closed in yesterday -- and won gold. The final 1600 in 2017 was also 4:05 and the final 800 was 1:57.55 (61.92-55.63, leader to leader) versus 1:57.1 yesterday (leader-to-leader). The race also featured a very similar first half split (13:33 vs 13:31 here). The difference is the 2017 Worlds had some crazy laps in the middle of the race (61 1st and 13th laps, for example).
What about the weather?
The weather in the two races was nearly identical.
The men's 10,000 in London was run at 9:20 p.m. Dark Sky reports that the temperature at 10 p.m. in London that day was 63 (at 8 p.m., it was 67), the wind was 2 mph and the dew point was just 56.
In Hengelo yesterday, the race was run at 8:50 p.m. local. Dark Sky reports that the temperature at 10 p.m. in Hengelo was 63 (at 8 p.m., it was 70), the wind was 3 mph and the dew point was 55.
What do you think?
