Opinions as to why both 100s so slow

Wasn't there like a 3.0 headwind?

No.

1.0 and 1.7

Sorry, -1.0, -1.7

In hot weather, gas molecules in the air are spaced further apart. As a result, sound propagates with less speed and efficiency (this is why you can hear distant sounds more clearly on a cold winter day). This makes gun reaction time slower because the sound isn’t heard as quickly.

Sprinters today are also much lazier than they were a couple of years ago. One coach said these are some of the laziest guys he's ever coached. So, there's that.

ah, thought I heard one of the newscasters say there was a "into a 3 wind" must have mis-heard.

Yikes , those were some slow races . Any ideas why ? Better drug testing ? Slow track ? Quality of athletes down ?

Thank you for speaking in code so that no one understands this post and certainly in 10 years when it gets bumped up it'll make even less sense.

Could have sworn the women's race was originally posted as -3.7. Your stat makes Richardson's performance even more dismal. That sort of drop off for a 100m sprinter looks quite weird. Daniels' college season was a month longer and she seems to be improving every month (along with shedding some serious lbs).

Clavon Gellespie is the first Oregon Duck to ever run a sub10.00.

Christian Coleman is a 9.7 cat.

Mike Rodgers has been on how many USA teams?

Chris Belcher is the only HBCU sprinter to ever run a sub 10.00 while in school.

How anyone could think the quality of athletes is down,...???

That drug thing is so worn out.

What is the track record in a 100m?

Richardson seemed to give up after a crap start. Daniels seemed as surprised as anyone that she won. It will be interesting to see how Bowie does in Doha.

9.89 from last year, although it doesn't say who holds it or under what conditions. Some of these USATF pages need serious work.

What is Bowie doing to show her "fitness?"

I can't keep up with the Byzantine rules for qualification, but it appears that, as defending champ, she just has to show up.

A headwind, yes, but it's of the male semi that was run into a - 3.7 wind.

It looks that every single race in the 100m , from the 1st round to the final, were run against the wind...

Flan, you are no science man. It's the opposite of what you think. Sound travels faster in warm air than cold air. This is due to the relative amount of energy on warm air, not the density. Regardless, the difference in sound speed is not significant enough to alter the reaction times.

When comparing the speed of sound across various mediums, the denser medium will conduct sound faster than the less dense medium, however, when comparing sounds within a particular medium, the warmer (less dense) state will always conduct sound faster than the colder (more dense) state.

So, water conducts sound faster than air.

Warm water conducts sound faster than cold water.

Warm air conducts sound faster than cold air.

Salt water conducts sound faster than fresh water.
