Racing the 5000 this weekend and at start the temps are supposed to be about 90.
I did the temperature adjustment on Jack Daniels and it says add 13 seconds a mile... which seems a bit excessive.
My goal is to run 15:15 and I feel as though this doable on a cool day.. but am I being overly ambitious given the temperature?
I guess what I'm really asking is about how much do you guys think 90's will affect race performance?
Unless you are in significantly better shape than when you set your previous pr, the chances are pretty low.
If the sun is not up and humidity is low, you might have a shot if your current PR is week.
It completely depends on how you respond to hot weather running. Bill Rodgers, among others, was terrible at it. Some people (like myself) know they are going to have a good day in the heat, relative to their competition.
So the question is something you can only really answer yourself based on your previous experience with the heat. If you know you don't run well in 90 degree weather, you aren't going to PR.
Lastly, humidity will make a tremendous difference. 90 degrees with almost zero humidity is almost perfect for me (low 80s would be better), but 90 degrees with 90% humidity would be very tough on anybody.
Paul Chelimo solo a 13:08 by himself in some brutal heat.
Where is this race? Phoenix?
I think you’ll be able to keep goal pace through halfway but then it will feel like a death march toward the end. I predict 15:45,
Report back and let us know how it goes!
Yes. It is in PHX.
One thing that's always bothered me about Daniels' temperature data is that it doesn't account for humidity. In Phoenix this time of year you might be running in 90 degrees with 10% humidity (~30 degree dew point) which is much less stressful than running the same temperature in a high humidity environment.
