Notes
First tempo run in a LONG time. Beautiful evening! 80 degrees, 25% humidity, DP 42, wind E at 9 mph. 1 mile warm up then shooting for 4 miles at 8:30 pace then 1 mile cool down. The interval settings on my phone went haywire somehow, but I'm pretty sure I ended up running a bit faster than 8:30 on the 4 mile tempo section. Kept my HR under 180 the whole time. Under 170 the first 3 miles of the tempo section. Overall avg pace 8:58, overall avg HR 158. Very good workout.
