I had an athlete (Nicola Ciavarella) working as school caretaker, already 32 years old, without big talent (14:48 in 5000m and 30:31 in 10000m), training once per day only with a volume of 120 km per week, able to run marathon in 2:17 and very constant (10 times under 2:19). When his wife waited their first baby, he could ask 3 months of leave with pay for paternity, using that period for training twice per day, enhancing the volume of his mileage to 220 km per week. After 3 months of this preparation, he was 2nd in Napoli Marathon, running 2:11:21...
Many of us are untalented, old, have similar times, and would like to attempt something similar. What kind of workouts was he running? Grazi
