jeez !
how dumb are you ???
if it was from behind, she gets 2nd advantage apart from winds upto 9m/s behind her, from pacers "cutting" thru air in front of her at :
42195 / 135'25 =
5.2 m/s
with perfect drafting in still conditions, paced from gun-to-tape, a 2"15'25 has to be considered from physics as
2"15'25 (+5.2)
impress me :
go to to mureika's wind/ altitude calculator, input what 42195m in 2"15'25 for 100m is, then give it 5.2 m/s wind, then big up "basic" time back to 42195m
then try & learn from that what a perfectly wabbited gun-to-tape run couda given her as un upper limit advantage even without consideration of winds of upto 9m/s blowing her behind
Possibly on the double advantage front but you are not going to need someone to cut the wind if is so strong behind you. Anyway the wind was not behind her all the way was it there is no way the wind is going to keep changing direction to go exactly behind her. Take another look at the map you are talking nonsense. The other idiot could take a look as well as its not a loop course and he might have made a better argument if he'd known that
So the wind is going to be in her face for part of the course and if had ever run you would know a head wind slows you more than a tail wind speeds you up
You have forgotten something extra as well- all races have pacemakers so she is only gaining anything extra for the 6 or so miles by having pace makers to the end.
Then you have not taken into account that London is not that fast a course, Berlin is a minute faster
Finally if conditions were so favourable why did the male winner run 2:07:56
