Pikes Peak Greenway Long Run

20 Miles 2:17:58 6:54 average per mile
9:30 am) 50's Sunny!
This run was a struggle today. I felt okay till mile 11 then
for some reason I started to bonk. At 14 miles I wanted to
end the run. I decided at 14 that 22 was not going to happen
and told myself lets at least try for 20. Got the 20 miles
so happy about that but am wondering what happened today.
Maybe just an off day?
My splits to give an idea of the slow down. Never really
crashed but did slow down.
