2 additive possibilities
1) ~ 400m altitude offers virtually unchanged O2 saturation of hemoglobin, but some significant recuction in air-resistance to running
2) it's in a heavy forrested area ( watch the video - see the surrounds ) with lots of tress pumping out O2
the track atmosphere, instead of normal 21% O2 may be offering nearer 22 or even 23% O2, thus offering more O2 to the runners
similar phenomena to 2) can be seen in webb's belgium runs of 1'43/3'46 - check the vids
I will translate for those of you who want to read this:
It's not the track, it was reLAID in '04.
TWO additIONAL possibilities:
1) The ~400m altitude offers virtually unchanged atmospheric concentration of O2, but some significant reDuction in air-resistance to running.
2) it's in a heavILY forested area ( watch the video - see the surroundINGS ) with lots of tress pumping out O2.
The track atmosphere, instead of A normal 21% O2-concentration, it may be offering nearer 22 or even 23% O2, thus offering more O2 to the runners.
A similar phenomena to 2) can be seen in Webb's Belgium RACES of 1'43/3'46 - check the vids.
