I just got a pretty nasty cold this past week (still trying to get over it! UGH) I called in sick to work one day then went out one day this weekend. I wasn't really feeling up to riding so I just did some liberty work with my horse then let him graze. The fresh air felt really good but after a half hour I just wanted to go home and sleep. In all honestly I probably should not have been even driving I was so "out of it".
I agree with others...if I call into work or school then I don't go out that day. I would just focus on getting better:)
