Not the greatest day out on the trails. First, I misjudged a steep rooty drop down near the creek on our neighborhood trails, and fell hard on my left side. I was fine once my wind came back. Later on over by Line Creek I washed out my front tire on loose leaves and pinestraw on a sharp right. Couldn't get my foot out in time so I went down on my right side, not hard but somehow in the process really banged the side of my knee on my bar end. Really stung, but once I shook it off it was fine. I turned around and began heading back to the BSC. I began to see what I thought was sunspots from looking at bright lights. But after pausing and focusing, I realized that indeed I had begun to have a blurry spot forming right in my field of vision. Great. So I rode back extremely easy, knowing that more blurriness was coming and that i'd soon have a migrane. I stayed on the trail despite my better judgement although I really took it easy. I don't think it was from any hits to my head or anything, I think it was just sort of time for another migraine, they seem sorta random. I felt really exhausted from the cumulative effect of all the extra physicality of my 3rd week at a new job plus doing maybe a bit more volume on the bike than I maybe should have. I felt horrible after getting in from this ride and although I slept really good the night after, I took it as a sign that I probably should take it easy a bit this weekend.
