Effect Of Temperature On Marathon Time

Do any of you know of any quantitative relationship
between temperature and marathon finish time. For example,
if you finish in 6 hrs when the temperature ranged between
80 and 90+ degrees F (LA marathon) what can you expect for
a future race when the temperature ranges between 50 and
70 degrees F or 40 and 60 degrees F with no other changes?

No other changes? How are you going to guarantee that?

I would have said that, for a distance race, especially a
road race, especially a marathon there are too many other
factors (course, wind, and the most important, fitness) that
would make meaningful results impossible to extrapolate.

I pretty mutch agree with Edward. Since a 6 hour marathon
is about a
13:45/mi pace (fast walking pace), I would think that if you
could manage to run the whole way, that would reduce
the time dramatically. One of Bob Glover's rules of
thumb is you can count on an increase of one second
per mile per degree above 60. His rules of thumb are
overly simplistic, but surprisingly accurate. Accuracy
may go down due to other factors in the marathon.

There are too many variables to make this kind of
analysis. Some people run better in the heat, some run
better in the cold.

No way. Heat slows you down substantially. Cold doesn't
(well at least not until you get well below zero
fahrenheit). You're almost certainly going to run a faster
time in the cold, the only question is how much faster. Most
of my friends who did Boston this year (for example) were
off their bests by 15 minutes or more.

Simplistic, but David Martin (author of "Better Training for
Distance Runners"😉 figured that out using race performances.
Not the best way to do it, but the only practical way.

Some people do prefer heat, that being said I'm not one of
them. I definitely run better in cool or cold weather. Our
coach who has a 2:19 PR in Boston was asked by many why he
wasn't running when we were there this year because it was
"his kind of weather". Another woman on our team is also an
example of this. My wife and this woman usually finish
within a minute of each other in Marathons they have both
participated in. She beat my wife by 15 minutes in Boston
this past year and had a better time than in 2003 when it
was cooler. There are other factors besides the temperature,
the humidity levels and wind have to be taken in account
too. If there had been high humidity I don't think I would
have gotten to the finish at Boston without assistance.

I think he meant some people run better than other people
in the heat.
