For any of you who are not sure that Maffetone is nuts, here are some other gems:
"While a monthly assessment such as this one is important, one need not necessarily run on a track to evaluate improvement. During any given workout on a familiar training course, the same type of general assessment can be made. One-mile splits are not necessarily required. A one-hour loop, for example, will take less time to complete with each passing week."
I am pretty sure that the one-hour run will always take one hour.
and this ...
"How fast will a runner’s aerobic pace have to be to run a 1:59 marathon? While this can only be precisely answered after the race, there are relationships between ones aerobic speed and race pace. For example, for a runner to break 14 minutes in the 5K, ones aerobic pace would have to be around 5:30, which would equate to a 4:30 race pace. Likewise, for a sub-30 minute 10K, an aerobic pace of around 5:15 might be necessary. "
Whose "aerobic pace" would be faster? a 14:00 5k runner or a 30:00 10k runner? Everyone knows that the 14:00 runner is better, but this clown is blinded by the idea that a 30:00 runner is better aerobically because the 10k is longer.
Hopefully, only hobby joggers listen to this clown, for their own sake.
