What does this actually mean? Is it that you can run your normal paces and efforts when youβre acclimated? Or just that you donβt die while running? π Weβve really just started seeing heat and humidity here for the summer and everything I read about heat acclimation says you should be acclimated within 10-14 days. This is my 5th summer in hot and humid Tennessee and I donβt think Iβve ever felt acclimated. My easy pace, keeping HR low is always about 1-1.5 min/mile slower in the summer. Which makes me feel that Iβm not making any progress - although I know I am! Thoughts?
