One of the most common mistakes we see runners make is running too fast on “easy” days. This happens a lot because of the notion that if it feels easy you must not be training hard enough. And then on days when temps are high most will still try and stick to their pace as much as possible without considering the fact that they’re making the effort much harder than it’s supposed to be. For instance, let’s look at some quick stats:
What effect does 80 degrees have on my easy run effort?
-If you’ve recently run 24:00 for 5k your easy day pace range (65-79% HRMax) should be roughly 9:49-10:23 per mile
-If you’re going out to run on an 80 degree the same effort would be about 18 seconds slower per mile or 10:07-10:39 per mile
