Ran 8 miles with Ted in the Provo Canyon in the evening. 4 miles up in 29:22, then 25:58 back down. Did not think I could run that fast without serious consequences, but Ted went, and I went with him, and as of almost 24 hours later still no negative consequences, actually feeling much better.
HR still high - 140 going up, 145 going down. However, the faster the pace, the closer it seems to get to normal. Resting HR also normalizing - got down to 59 while driving. The cough is still very strong, but I felt a lot more motivated to run than anytime since Wednesday.
Came home, ran with the kids. Scared the neighbors with the cough.
Taking large quantities of garlic and onions, lots of water, that is helping quite a bit.
