Das man solche Einheiten machen kann bezweifle ich nicht.
Schon Zatopek ist 100*400m gelaufen.

The hard-working Czech was known to rattle off 100(!) of these 400m reps per day, alternated with 200m recoveries. Scientists later reckoned (op cit) that Zatopek reached lactate-threshold speed at about 85% of his VO2max (ie. at a pace of about 72 seconds per 400m), which meant that on a 100-work-interval day he was completing about 40k of work intervals in just 120 minutes or so. (Before you become completely incredulous, don't forget that there were 39 'recoveries' injected into such running to make the 100 x 400 scheme more palatable.) Zatopek's pattern of churning out high volumes of moderate-quality (below 90% VO2max) training was echoed, albeit on a less grandiose scale, by the American runner Jim Ryun in the late 1960s and early 1970s.
