Anyway, after a 101-mile month (almost 26 hours of running), I saw some improvement. Here are my stats from the beginning until today:
Sports Complex (5km) at 121-131bpm:
|October 31||November 30||January 5||January 31||March 3|
So I'm gonna stick with Maffetone for most or all of this month to see if I see more improvement next month. I have a trail race in mid-April so I may be a little bit undertrained for it in terms of hills. But I should be okay for endurance!
