no
no one has said that it is 0 disadvantage, just some gut feeling
some hard numbers :
nairobia at 5450' ( 1661m ) according to wiki
ncaa tables
( which don't say anywhere that it doesn't count for kenyans )
give denver as nearest elevation at 5279'
http://www.letsrun.com/2010/altitude0224.phpthat says a 1'48.69 clocking is handicapped by 0.69 or 1'48.00 basic
therefore disadvantage ratio is 108.69/108.00
now, i don't believe those tables factor in lower air resistance, only hypoxia on aeobic metabolism
2nd factor is wind/altitude calculator :
http://www.letsrun.com/2010/altitude0224.phpa 1'42.12 is 51.06 x2
51.06 at 1661m is 51.44 basic or helping ratio of 51.06/51.44
therefore rudy's sea-level time was ~
1'42.12 * (108.69/108.00) * (51.06/51.44) =
1'42.01
i'd say nairobi handicapped him by 0.1s overall
it is different situation for mexico where i'd expect handicap to be lot more
