I am currently on day 16 of my Whole 30 journey and following the program as exact as possible, poor fiance hates that I spend more time reading labels anymore..
I know there is a curve from going from sugar energy to fat adapted and I'm slowly getting my runs longer and faster, however I'm experiencing something new... My resting heart rate has dropped since starting Whole 30 from 65/67 to 59/60 but my running heart rate has jumped through the roof.
Example: Resting heart rate today as 59, but my 4 mile run of a 9:35, 9:24, 9:14 and lastly 8:44 had my heart rate well above 155-172 at it's highest.
Has anyone else experienced this before? I have done about 20 half marathons and am not new to running in any respect. The above times are significantly slower than I was running pre-Whole 30 but the heart rate has gotten higher. Really trying to get a grasp on this whole thing.
Thanks so much for any and all advice!! I feel like I'm some anomaly at the moment.
