Hey all!
I saw this over in one of the Running World Forums and thought of all of us Princesses who are dealing with humidity:
Here is a "rule of thumb" I found years ago that seems to make sense:
TEMP+DEW POINT (Add the temperature and dew point values together):
=======================================================
Below 100: Ideal
100-120: Not ideal, but ok to go for a fast time
120-130: Ok for fast pace in races up to 10K - adjust for slower pace in longer races
130-150: Adjust for slower pace in all race distances, especially longer races
Above 150: Forget pace - just focus on finishing
FYI - The dew point temperature is the temperature at which air can no longer hold all of its water vapor, and some of the water vapor must condense into liquid water (e.g. condensation in the form of dew, fog, clouds, etc). At 100% relative humidity, the dew point temperature and real temperature are the same, and clouds or fog can begin to form.
While relative humidity is a relative measure of how humid it is, the dew point temperature is an absolute measure of how much water vapor is in the air (how humid it is). In very warm, humid conditions, the dew point temperature can reach 75 to 77 degrees F, but rarely exceeds 80 degrees. By definition, the dew point value cannot be higher than the temperature.
Right now in Gainesville, it is 80* with a 75* dewpoint, so this would be 155 - putting us in the realm of "Just Finish" !! I think that this little formula will help me gauge how I should run my outside runs now. Hope this helps you guys!
