This is his training during the first two weeks of training after a Marathon. After a Marathon he relaxes for about two weeks, with active rest (running easy only once per day from the second week), than starts THAT art of training.
The last 3 months before a Marathon are completely different.
A lot of LONG FAST RUN (Geoffrey ALWAYS runs fast, under this point of view more than Wilson Kipsang and Moses Mosop), some vey easy jogging used as recovery, most of times replacing massages, and a lot of Fartlek (only sometimes on track, not for technical choice, but becase he doesn't want to travel too much for going to the track from his camp, very far).
The idea some top Kenyan can run at 8' per mile (about 5' per km) is totally ridiculous, except you think the most important part of training is REGENERATION. Kenyan runners understand very well the difference between TRAINING and RECOVERY, something few people posting in LR instead are able to understand.
With these athletes, we can say that about 50-60 km per week are very slow, because they don't have the possibility to use some alternative type of training for recovering.
So, when we say 240 km, we can read, for an American or European Marathon runner, 180-190, plus the utilization of alternative training (for example, ski roll or ski cross, biking, swimming, depending on the period of the season).
People must learn to look of the REAL TRAINING, not only to the mileage. Everybody has different interpretation about HOW TO COUNT THE MILEAGE, and this provokes a lot of misunderstandigs. If we use to count warm-up, cool-down, jogging between tests on track, may be also when you use stairs in your house, mileage can raise.
I remember the great Ron Hill, who never wanted in his life to have one day WITHOUT mileage. So, when he had a surgery in one leg, the same day went on the aisle of the hospital jumping on the fit leg, for writing on his diary the mileage of "200m" also for that day.
The opposite was Peter Coe. He wrote about the mileage of Sebastian considering ONLY his specific workouts, not including also some long fast run Seb used, and this provoked big misunderstandigs among coaches discussing his method. Ask Seb if his mileage, especially during the period 19-22 years, was really 45 miles per week, or sometimes also 100 !
