Grade: 3
Cold, sore throat developed later.
Unpleasant cold which started out light, but then, due to work/lack of sleep, developed, including a sore throat. Felt exhausted a couple of days after helping with Ultraloppet Fri/Sat. Spent those days on the couch sleeping lots which helped recovery.
This cold was mainly a result of several late nights trying to get work done, perhaps in combination with the resulting tiredness in doing three 'races' in four days (14th-17th).
