8 miles

Did the 8-mile loop in town today. Wore a heart rate monitor which was distracting but interesting all at the same time. Average heart rate was 155 and max. heart rate was 174. The route went well and I ran it in about 1:13:30. I focused on shorts sprints that took the HR to 165-170 and then short recoveries back done to 150. Many repeats of this.
