I noticed very mild throat soreness yesterday in the morning, which didn't get any worse during the day, but became more noticeable in the late evening.
Since I coudn't feel any other symptoms and felt otherwise 100% fine, I decided I could go skiing, and did so, keeping to an easier effort level, and shortening the duration form what I would usually do.
This morning my throat was more sore, but again, there were no other symptoms, and I felt fine during the day, and again decided some outdoor exercise would be fine at a very easy intensity. So I skied, and linked up with several friends for the last third or so of the ski. Still felt fine, so I jogged a bit after that.
This evening my throat is definitely sorer, however, and that's no good, even if I still feel perfectly fine otherwise. I will not be surprised if I wake up tomorrow not feeling so great. Normally when I get a sore throat, it is followed by fever within 24 hours, so this is unusual for me.
The skiing/snow was really good today, if thin in spots.
