For the past couple of days, I've had a RHR a bit higher than normal (I check it every morning, within minutes of waking up). It's usually between 44-48, but has been 50, 56 and 50 the past three mornings.
I've also experienced poor sleep and unusual fatigue during the late afternoons (fell asleep for 1-2 hours at 5 pm both yesterday and the day before). No cold, no allergies, no stress or any other such problems that could produce similar symptoms.
No pain anywhere. No bad moods or irritability. Physical performance seems unaffected.
I've decided to nip it in the bud, in case this indeed is overtraining, and stay off my bikes completely at least until Thursday, and possibly longer if I feel I need to by then.
Does this sound like overtraining?
