In the "hard events" of Running, Jumping,or Swimming has there ever
been an Olympic Games you know of where a woman achieved a 90% or
better score than the male gold medal winner?

You only need to check  a handful of the last few years to qualify for
immediate payment. Thanks

Dear  mcisencraft, 

I followed the ermarks of sports and gender specialists that in "long
distance swimming women perform better than men". It is claimed that
while woman are not as strong as men, they have more stamina.

Better, I am yet to find. However, at least 90% as good, exists in long distance. 

In Triathlon, an Olympic event, which is composed of swimming, running
and cycling, women did at least 90% as good as men:

Sydney, 2000, results (for the whole course): 

Brigitte McMahon (Switzerland) 	02:00:40.52 

Simon Whitfield (Canada) 	01:48:24.02  

(SOURCE: Olympic Results,
<http://www.worldwideaquatics.com/olympics/results.htm#TRIATHLON>).

There is also a book on the subject of why woman *could* fare better
(or as well) as men in sports :
The Frailty Myth Redefining the Physical Potential of Women and Girls
Written by Colette Dowling 
<http://www.bookclubs.ca/catalog/display.pperl?isbn=0375758151&view=rg> 

Again, from the latest in Sydney: 

In 400m Individual Medley: 
Yana Klochkova (Ukraine) 	04:33.59  
Tom Dolan (United States) 	(W) 04:11.76  

(SOURCE: "Olympic Resulst"
<http://www.worldwideaquatics.com/olympics/swimresults.htm>) (W means
World record)

[There's also 1,500m swim for men and a 800m swim for women, but
there's is no gender equivalent in each case].

Regarding running, there is no Olympic event, including marathon,
where women do better than men. In a non Olympic event:
"Because sometimes an ultra-run has been won by a women it is said
that women are relatively much better than men at those distances. But
record lists did not support that thesis, on the contrary. Women's
records for ultra distances were all much weaker than men's records,
until a rather good Japanese marathon runner (2:26:09) tried a 100 km.
Tomoe Abe smashed the women's record and at the same from that moment
all men's records did look pale."
(SOURCE: Weia Reinboud, "WORLD RECORDS 50 M - 24 UUR COMPARED",
<http://www.antenna.nl/weia/RunningRecords.html>).

Abe is not the only one. It seems that in "ultra running" (much more
than marathon), women fare better than men, or as well as.

In Marathon, there is though 90% performance: 
Men's Marathon. Olympic Games 2000

I hope this answers your question. Please contact me if you need any
clarification on this answer before you rate it.

Seach strategy: 
women olympics "as well as men" / "as good as men" / "better than men"

Good job. I didn't want any event that used any kind of appliance like
a bicycle,fencing foil,etc.  THIS WAS A WELL THOUGHT OUT ANSWER YU
GAVE, THANKYOU
