Lunch- workout with Jim. Beautiful day for a workout- upper 60's, cloudy, and a slight breeze. Ran 2 miles to the lake, then started a tempo around the .85 mile loop. We planned on sub-6 pace, but ended up going much faster. Hit the first 5k in 17:30, second 5k in 17:16, and finished the 8.1 mile tempo in 45:34 (5:37 avg). All the miles were between 5:31 to 5:44. Could have done more as I felt good (well, at least the second half, though I slowed some miles 6-8), but I have a 5k this Friday and a 50 miler next Saturday. 2.5 mile cooldown. 12.5 total in 1:20 (6:27 avg). Fastest tempo in years for me, maybe ever. Felt good to run fast.
