In my second workout of the day, I ran a basic 4 miler. I held a steady pace of about 7:45/mile for the duration. I was definitely tired though, understandably. I have 24 miles in for the week already and a couple cross training workouts.
It is noticeable though, after about 4 weeks, my steady pace has dropped. I started in January running around 8:30-8:40/mile comfortably. Now, even on tired legs, I can go more at a pace around 7:45-7:55/mile. I am planning to add some speed work one of these days and try to drive down my overall pace even more.
I do need to remember my long run pace needs to slow down sometimes. I want that pace to be somewhere between 8:15-8:30/mile for now.
