Fun ride yesterday, freaking exhausted today

Yesterday I did another great route, but I had to call an audible about halfway through. I had mapped it out, but unfortunately, the map doesn't distinguish paved from unpaved roads. So I got to where I needed to turn and was not about to do another climb on a dirt road. The funny part was that I saw the road and was pretty sure that was it. So, I pulled out my phone to look at the map. Of course I was in a dead zone, so as I'm sitting there waiting for it to load I hear some kind of weird snorting sound. And then I heard it again. I don't know where it could've been coming from as it was fairly open where I was standing, but there were some obstacles. The only thing I could think of was a bear was not liking where I was standing and was kindly telling me that I should be moving on. I chose not to think anymore about what it was, assume it was a bear politely asking me to move and I responded to his request. But all in all it was another good ride. My speed has been way up considering the hills, my HR has been at a decent level, low enough that I had plenty more in the tank for race day confidence. My exhaustion today though, wow. It's probably related to going to bed later than usual last night and perhaps adjusting to the new workload of training. Fortunately, after tomorrow I get three days in a row to sleep in. Oh no I don't. Early race on saturday. Well, I have two days to catch up. Going to be a fun weekend though. Biltmore lake is a great race.
