I have read that when your resting heart rate upon waking is 5-10 bpm above normal, that is a sign of overtraining. Mine went to 56 this am. It's usually in the 44 to 51 range.
I have read that if you do a workout, and despite your best effort, you results are terrible, that is a sign of overtraining.
I've done sprints at Arcadia. My best mile was 7:35. My worst at a sprinters pace was 8:05 (or thereabouts).
Yesterday, I did the CrossFit Endurance WOD from Tuesday which was: run for 20 mins at 95% RPE (Rate of perceived exertion--defined in this case as very hard exertion).
I ran as hard as I possibly could. I could not go any faster.
The best I could muster was 2.35 miles in 20 minutes---essentially a 9 minute mile. This sucks!!!! I haven't run this poorly in a very long time.
So I refuse to feel bad about taking today off. And as we have a race on Saturday, I am also going to take Friday off. (I also have to acknowledge that just maybe running the marathon had something to do with this?)
The good news is I have no more races until Mt. Wilson!
This means next week, I'll be back at CrossFit and O-lift full force. Only this time, I'm going to make sure I rest as RX'ed!!
