Ran to Sugarhouse Park and did two loops hard (did a little bit extra warmup). I wasn't really comfortable as I had phlegm in my throat that made it hard to breathe hard even though I didn't feel like I had any other symptoms. I ran 11:12,11:01 for the two loops which is 5:33 pace for 4 miles. I pushed the end of the last one hard and then I began to notice that I might be a little sick. My heart beat was a little irregular for a couple minutes after I stopped, which isn't unusual. So mentally, it wasn't a tough workout, but I'm not sure I could have handled much more.
