I'm turning 40 on Monday and am going to have myself a little mile time trial on Sunday. Haven't raced it in 18 years.
I did 12x400m last weekend averaging 82's (84, 84, 84, 83, 82, 82, 82, 83, 82, 81, 80, 80).
Based on this, I figured, 83 would be a reasonable pace to go out. Going to see if I can get under 5:30. Any thoughts?
