Io direi di restare fermi a quello che scrive Symmonds, che è già molto dettagliato, senza aggiunte spurie.
Lui dice questo sulle corse lente:
More often than not I will mark down the miles that I ran, rather than the number of minutes the run lasted. I typically run my easy mileage somewhere between 7 and 8 minutes per mile. Also, while I do take two to three weeks off at the end of each season, I stay very active during this time with plenty of hiking, surfing, fishing, etc. Mileage is usually a close estimate, though I sometimes run with a GPS watch.
Quindi siamo tra 4'20/km fino a 5'/km.
Per i lavori di potenza aerobica, utilizza molto l'alternanza forte-medio-forte e le progressioni.
Questo, tra gli altri, è un lavoro che mi ha molto impressionato:
Friday, December 2, 2011 9 miles
3mile warmup. 12x(1 minute on, 1 minute off). #s 3, 6, 9, and 12 @ 1500m pace...others at 5K pace. 2mile cool down.
This is a fantastic workout. Very manageable mentally. I was trying to hit close to a quarter mile for the fast intervals. The slower intervals run at 5K pace were probably close to 70 second pace for a quarter mile.
