Blue fingernails at the end of workout

You might have pneumonia. Seriously. If you notice breathing problems get it checked out.

Any lightheadedness? Does your HR drop sharply right after you finish a repeat? In some severe overtraining where your parasympathetic nervous system get overactive, your heart rate drops too fast while the vessels in your muscles are still dilated, so your blood pressure drops and you don't perfuse well.

Or, even simpler, were you running outside in the cold?

If no HR drop/dizziness the other poster is probably on the right track.

None.

My resting heart rate is 39. I have a pretty low max though. I don't know about over training. I've only done 4 track workouts in 3 weeks. Mileage last week was 62 miles, which is pretty run of the mill for me. Went easy Monday and Tuesday.

Perfusion isn't a problem, nail beds were not white, and purpled up a split second after pressure was applied. Made sure I was hydrated before the workout as well. I was running at an indoor track. All I got was that weird headache which I had on Saturday when I did a 10x200. The workout was fine but I felt pretty sick after, the over exertion sick not throw up sick.

Any chance of anemia? Is your training going OK otherwise?

Well, I gave blood a couple of weeks ago and they tested my blood at 159g/L of Hb which is upper mid range. But anaemia wouldn't likely be the case because all of the given Hb in anaemia would be bound to Hb anyway making it unlikely to be the case.

I have had a tad bit sore throat for about a week that I can't seem to shake. Its like a sore soft palate only when I get up in the morning, then I have a lot of green gunk up in there.

Training is going well otherwise. I can easily do the mileage, I've just been maintaining the same amount and adding in the track workouts on top.

That's called cyanosis. Not a good sign, seriously.

you may have a bacterial throat infection. I'd see a doctor.

Yes, I'm aware. More specifically it's called peripheral cyanosis.

Any reason this would happen in a workout other than pneumonia.
