I was dog tired before I started tonight having worked late again. Set out at 7:30pm intending to run 10 miles. I ended up tagging an extra 2 miles on for 12 since it was a cool night, I even wore a long sleeved top.
Since I felt so tired I didn't attempt to run progressively, instead kept the pace easy and bagged the miles.
On reflection I did pick the pace up a little Inthe last 5 miles. I started the run with a first mile of 8:15 but the last five averaged 7:35-ish so not bad considering.
