Notes
14-16 miles, at MAF for the first ~10
Then run 10 X 1:00 hill intervals.These aren't maxed out, just strong & controlled. HR max would hit ~175 is all. Build in to each. Jog easy back to the starts.
Finish the run easy and relaxed."
Legs feeling fatigued for the first 5+ miles... feeling good by the hills, and then better after that.
