What is your Eddinton number? "When not doing astrophysics, Eddington was an avid cyclist, taking long tours of England each spring and fall. He kept track of all his routes by tracing them on a large map, and devised a criterion for tracking lifetime cycling progress. This criterion was the largest integer n such that one had cycled at least n miles on n different days." My Eddington number is somewhere between 25 and 30, so I'm really a beginner. Eddington was doing 80-mile tours by bicycle at the age of 61.
