Ya- forty miles..40...
Now before you roll your eyes and shake your head, I did this because of a race I will be doing in a month that will require me to run about this far. I also split this run up as follows:
8 miles in 1:00
6 miles in 40:00
4 miles in 26:00
8 miles (95+ degrees) in 54:00.
6 miles not sure on the time, math was beyond me.
Total time 4:41:02/ average HR 142. 7:01 average pace.
This is roughly how I will need to run that race- split runs.
I'm going to go and lay down now.
