I was on day 10, and was resting comfortably
in a hostel for the next couple
days due to repairs on my bike and snow
in the forecast.
I stopped riding Monday afternoon, and the following Tuesday morning, while resting comfortably in the lobby, my heart started converting between 60-160. I started timing them. It did this for the next six days often waking me up at night.
Anyway, back to the story. I literally walked across the street to a medical clinic...W. Yellowstone...
