In the genre of marginally meaningful statistics, I find the Eddington Number interesting. The largest number of miles you have cycled or walked on the same number of days. It can be calculated over any period of time; typically over lifetime and annually.

My lifetime is 125, meaning I've ridden 125 rides of 125 or more miles. That's due to many 200km randonneuring rides. I need eight more rides of 126 or more, to increase it to 126. That'll happen, but I'll likely never top 130. I need 32 more rides of 131 miles to reach 131. The next randonneuring distance is 300km, and I don't see myself doing 32 more 300k rides. Or maybe I will, who knows. Eventually that lifetime number will top out, and the annual number will become the one to watch. My biggest annual number was 2023 where at 63 it was 41. I can imagine a bump on that number after retirement.

Interesting, but meaningless.
