I started the Build Up program on Dec 12th. So far I have done the first cycle and now I´m during the second week (of three) of the second cycle, which should be the last. After it, a 4K time-trial.
During the three weeks of the first cycle I ran 139km in 14 runs, missing 3 of them. Not that bad considering the holiday season, right?
All these runs are done on an easy effort (as close as possible to 145bpm), so they´re light aerobic and the purpose is to get the body used to a running routine.
The easy days are ending and very soon the speed work will be back to my schedule.
