[i]The Seven-Year Rule

Runners improve for about seven years.

Mike Tymn noticed this in the early 1980s and wrote about it in his National Masters News column. „My seven-year adaptation theory was based on the fact that so many runners I talked to ran their best times an average of seven years after they started,“ he recalls.

The Exception: Low-mileage runners can stretch the seven years to well over a decade before plateauing.[/i]

už se těším, co mě čeká :)
