running (running ) 1:00:00  9.2 mi (6:31 / mi)
slept:8.0 shoes: adizero tempo
15' easy, 4*(1mile @ 10k pace, 2' recovery), 15' easy.
So the average pace of the 1mile reps was 5'40'', I was really working hard to get up into that pace. I did the session on the flat roads of Battersea park. This was slower than I had hoped to do the 1mile reps and also required more effort. I did notice a very clear differential between the reps where I was relaxed vs the ones where I was fighting to maintain the pace, when I was more relaxed the pace was relatively easy to attain and maintain. Any thoughts or suggestion regarding how to learn to relax, or any interesting documented studies on the subject, would be very interesting and useful.
