I am hoping to break 5:45 for the mile and have signed up for a race. Temperature at race time is forecast to be 80 degrees. Jack Daniels calculator says that the temperature adjustment for 80 degrees is 11 seconds so 5:45 would be equivalent to 5:56. This seems like an over correction to me for such a short distance and relatively moderate temperature. I think I can barely hit 5:45 barely and all my training is pretty much in the morning before work/family life. Does 11 seconds seem right?

Even if it's humid and under the sun, no
If it's at dusk then 80F for a mile race would be great
You're fine. You won't overheat until it's over.
I'm an awful heat runner, and I've never felt like heat/humidity cost me anything in a mile. 5K or longer - yes, that may slow you down. Not in a mile.
When I saw the thread title, I was ready to read this post and roll my eyes, but I like the "no excuses" attitude.
I agree that 80 degrees for a mile race isn't too bad and 11 seconds seems awfully generous. If you are dealing with high dew points and direct sun too, you can probably excuse yourself if you miss your goal time by a few seconds, but if the dew points are reasonable, temps should be close to a non-issue
I run horribly in the heat, but I'd agree with everyone else that it's not going to be that big of an issue with such a short race. It takes time for your core temperature to start creeping up on you. I recently participated in a beer relay race and just wanted to get under 6 and I was pleasantly surprised to run 5:49. This was at 6pm and 77 degrees.
I'd say maybe half that. You probably won't even notice the heat until 800-1000m in.
Thanks for the feedback. Gives me a little more confidence, think I will give it a go.
hydrate well day before and day of. 80 isnt that bad for a mile
HaHaHa
You boys have got the wrong Daniels .
The souths gonna do it again. We call 80 degrees down here a beautiful day. Try running down here when it's 104.
My pr is 5:00.5 (the only mile i have ever run) it was 90+ degrees in direct sunlight. I figured the temperature had to be worth at least a few seconds. 11 seconds for 80?
I ran my fastest marathon of 2:35 at the hilly and hot Palos Verdes marathon in California.
The temperature at the finish was 95 degrees, and I blazed the last mile and a 1/4 at 5:17 mile pace.
The posters saying it's nothing are ill-informed, particularly on the claim that it's not as important at mid-d as distance. The drop in performance comes not from rising core temperature, but from blood getting diverted to the skin's surface to keep the core cool by sweating. This reduces its ability to deliver oxygen and remove CO2, which is more important (by far) in mid-d than a marathon.
In a distance race, where you run well within yourself gas-transport-wise, what gets you is dehydration which eventually short-circuits your cooling system. That can be staved off by hydration. But in mid-d, you won't lose water that fast, and staying hydrated won't raise your RBC count anyhow, so it can't compensate for the sweating. A certain percentage of your RBC's will be wasting their time on sweat detail whether you're fully hydrated or not.
If you train in the heat for several weeks before racing, your blood volume will increase, followed by an increase in RBC count to match. That compensates. Most anecdotes about racing well in heat are the happy ending to that story.
Temperature shouldn’t be an issue. Just look at NBN outdoor. 90 degrees, super humid, and in direct sunlight. Yet there were a bunch of great performances in the shorter distances (mile and under). The 5K and 2 mile are held at dusk (6:00ish) because that’s when the heat will have a serious impact on time. However, I believe the mile was held at like 1:00.

I vote this for the stupidest most ignorant post of the century.
Yeah, 80 is not bad at all unless you are doing some kind of crazy all out warm up beforehand and then standing in the sun until the gun goes off. As far as hydrating the day before and day of, not sure what that's going to accomplish in a 5 minute run?
