The workout was too long. 5 repeats of 1 mile loops at tempo pace and 1200m on track at 10K pace. The paces were too fast. 6:29 pace on the mile repeats, 6:09 pace on the 1200s. The last time I attempted this workout was prior to St. George 07. It was 3 or 4 repeats working off of the 3:15 marathon paces of 7:04 and 6:41. I puked. I didn't finish it. Today I completed all 5 repeats averaging 6:27 miles and 6:09 pace on the 1200s. It hurt. But damn it felt good to get the job done. I just found my St. George log: 3 repeats and I cut the last 2 to 800s on the track. Miles were 7:40s and track was 6:44 pace.
