well marius, i certainly believe you, but it IS hard to believe. i say this, be cause i have used the coe/martin program as outlined in "training distance runners," and i must say that the only athletes who have thrived on his training are the ones who did the most milage. the ones who showed up without a good aerobic base floundered in this program (i know many are saying, "of course, dumbass..." but it is worth noting that lots of coaches have stories about milers showing up unfit and getting really fast off superfast low-volume training. didn't work for us, though).
i find the coe program works much better with mid-distance, than long distance, but i also had a 10k runner earn all-america honors using that program- however, he never ran less than 80 miles a week, and most weeks were in the 90s! the milers i had, would thrive on this training only with a bare minimum of 60/week. but these were d3 kids, not world class runners. we were able to produce a few all-americans over 800-1500, but i can't imagine how they could have gone much faster without adding volume.
and i think this has probably been discussed, but i have also heard that the number of "units" of work in each energy system was performed by coe exactly as it was written?! how the hell can anyone do that amount of high aerobic/anaerobic running? he must have been the most naturally talented miler ever to walk the planet in order to survive that much hard running.
in our case, the kids ran fast 3 days out of 7 and raced another day...and i can tell you it took them right up to the ragged edge. i adapted the program to keep the amount of work within the RATIOS on coe's table, but i could never imagine them doing that many hard intervals. not many fell off the cliff, but they were at their limit. and honestly, if i had it to do again, i think i would have had them do more basebuilding as it probably would have been better in the long run.
