pm--7 Solo Trail Tuesday on the Rim Circuit. I tried really hard to keep the heart rate in a certain zone. I did much better today. It's difficult, though, on the trails with all of the ups and downs. But all of that is secondary when the day and the temperature are so beautiful. On another note, I'm thinking about really nerding out and giving all the SCRR trails Dune-themed names. RHR--52.
