This is a high mileage week. It starts today with the basic tempo runs as follow:
2 mile warm up, 6 miles at 7:50 to 8:00 pace, 2 mile cool down
I figure the tempo runs would be good opportunity to practice my pacing as well. And here are my times followed by some analysis: 9:55, 9:30, (7:53, 8:07, 7:14, 7:44, 7:47, 8:15), 10:04, 9:10
Looking at the 6 miles tempo/ pacing runs data in the table below: the first row are the split, the second row are the times outside my prescribed range of 7:50 – 8:00, and third row are the percent deviations. So take the first mile, the split is 7:53 and it is within the range, so no deviation.
The goal for me is to run steady (i.e. within the prescribed pace range, like the first mile). In future runs, I will work to bring the deviations down (e.g. -7.66%, the 3rd mile and 3.13% the 6 mile).
The causes for the deviations are over-correction from the second to third mile, fatigue on the last mile, and likely measurement errors because I run on the road instead of a track.
Hope your running is going strong, and you are reaching your goals.
