Running in Dry Heat

Robert said:

I run 5 miles in 80 degree weather with high humidity (50-95%)in 45 minutes without any trouble.
Does anyone know if it's as tolerable running in 110-120F with low humidity (5-15%)?

Ask the people that live in Oklahoma, Arizona, etc. - they do it every day. 😉 Want to see these

Heat conditions are only dangerous if you don't hydrate(fluid and electrolytes) properly. Running in
high heat and low humidity is deceiving because the water gets sucked out rapidly and evaporated
almost without notice. With high humidity the sweat clings and serves as a constant ugly reminder.

Some of my races are in temps of 75-90 degrees and humidity 70 - 90%. Staying hydrated is not an
easy task and can be very dangerous if not closely monitored in training and during the race.

Now, if there is a dog chasing you .... sorry, the devil made me say it. 🙂

my bro ran in midddle east , there was water concern ( corpsman) was watching him) running was ok.
there was sunburn concern . The water evapes off your skin so fast dehydrate is a prob, plus lips
can crack ,,, oh yes there was sand in shoes. plodzilla

I would suggest finding on the web one of the many heat index calculators and plug in the numbers to
see. www.acsm.org might have on its website a chart showing where exercise becomes dangerous based
on the wet bulb global temperature (which also takes into account the radiant heat from the sun).

If you are going from one condition to another, it is critical to acclimatize by running low
intensity, longer duration runs in the new environment (doing higher intensity stuff is not the best
approach). It takes anywhere from 7 to 14 days to acclimate fully. "Robert" <[email hidden]>

It's not the heat. It's the stupidity.

Rob, Agree w/ Sam on the climatizaiton. You'll have to hydrate ALOT due to evaporative conditions
w/high temps and low humidity. I ran in Saudi Arabia in September, temps @115 degrees w/virtually no
humidity. I'd down 1.5L of water 1 hr (in addition to my normal water intake) prior to running, then
drinking @ 15 oz of gatorade (or other sports drink), plus carrying 20oz on the run (normally 4-7
miler). I did the same thing when I lived in San Antonio and ran in the summer mos (Jun - Sep). It's
important, in a hot, low humidity environment to also wear a hat, and lighter colored clothes; use
sunscreen; & listen to your body! Also, monitor early morning to mid morning temperature increases
in hot climates. The mornings may deceivingly conducive to running, yet, within an hour, they can
drastically intensify (heat vs humidity). Hope this helps. R/Mark

Is running 5 miles in this temperature dangerous

To a daily runner, running just 5 miles anywhere almost cannot be dangerous. While I did take one
run in Death Valley on a trail up to an abandoned mine at about 120 F once in my 20's, it was not a
joy, due to all the sweat in my eyes. Plush headband a must. Actually, I have run at about 100 F
many times, here in the CA San Gabriel Valley, as well as in Las Vegas and the Phoenix area. It is
not dangerous, and you do get acclimated to the heat. The temps here in August/September/October are
one reason I personally switched to early am runs, as well as scheduling problems. Can't you run in
the early morning wherever this 110F-120F stuff is? Of course, I recall that in Phoenix when the
days top out at 115 F or so, it can still be 92-93 F at 3 a.m.!
