London's weather could play a big part in impairing athletes at the 2012 Summer Olympics.
And we're not just talking about the rain.
Health experts have warned that London smog could literally affect the health of athletes, leading to shortness of breath and chest pains.
An expert said:
"If there is a smog incident then athletes, especially in the endurance events, will not achieve their top performance and those who have any tendency to asthma will be badly affected. Athletes are exerting themselves to the maximum, taking in a lot of air. If that air is polluted it will inflame the air passages. It could have a significant effect on endurance events like the marathon, anything over 400-800m, even sailing."
The funny thing is London's rain keeps the pollution levels low.
The problem would be if it got really hot, then the pollution could react with the sunlight and heat and trap smog in the lower atmosphere for several days.
A professor of environmental health wasn't very worried though.
"London's normal level of pollution is not going to trouble athletes as the problem is most acute near busy roads where they will not be performing. I only anticipate a problem if the weather turns very warm and we have still conditions."
So hopefully there won't be any smog problems.
We want every athlete to be in top shape during the games so we can once again know who truly reigns supreme.
Who is that again??
USA! USA! USA!
