I ran into the concept of the 'Eddington Number' yesterday. I am surprised that I have never heard of it. See https://swinny.net/Cycling/-4687-Cal...dington-Number . In a nutshell it is the biggest integer (N) where you have (in your cycling life) ridden N miles in a single day N or more times. So if your Eddington Number is 50 that means that you have ridden 50 miles in a single day 50 or more different days. But not 51 miles in 51 different days, 52 miles in ..., etc .

Just curious about Eddington #'s out there. I restarted my cycling in 2014 and would guess that mine is in the low-mid 40's. I am a relatively high mileage type 6-10K per year, but have to be cautious when going over 3 hours due to knee issues.

ps. Sir Arthur Eddington is a early 20th century astro-physicist best known as the leader of the expedition that took star measurements (positional) during a 2019 eclipse (late edit - 1919 eclipse) and verified Einstein's General Theory of Relativity (and that measurement is what made Einstein a household name).
