They refers to the other guys training. Lots of volume and heavily endurance based but although the athlete has run low 49sec he’s been stuck there for a few seasons now.
My training bas been based around Charlies GPP & Vancouver download and the information on the Lactate thread.
The sessions that the guy refered to were in the Vancouver download for SPP long to short. So we would do 500 30min 500 + some high knee drills or later in the phase maybe 250 25min 200 what he failed to appreciate was that although there may of been only two runs they were bloody fast and much closer to our ideal race pace than 6x300.
