Eddington Number

The Eddington number, E, is the number of days in your life when you have cycled more than E miles.

It originates with Arthur Eddington, who was a physicist, who reached an E-number of 87 by the time he died in 1944. If you want to learn about his exploits in Physics then read his Wikipedia page. The idea is that increasing Eddington numbers isn’t all that simple of a feat once your number gets pretty good. To bump up from 60 to 65 all of the rides that you did that were between 60 and 65 are discounted and you need to do that many more above 65 plus the 5 actual rides to bump you from 60 to 65.

So the question you’re all wondering is “what’s my Eddington Number” I’m absolutely sure. Go calculate it! I don’t have any idea what yours is… unless you were on the SeatoSea bike tour and rode EFI (which means different things depending on who you are… “Every Fabulous Inch”, “Every Fantastic Inch” and of course some other versions. The tour prescribed that everyone would complete enough rides to score an imperial Eddington Number of 48 and a metric Eddington Number of 53. The metric one isn’t as good of a measure in my opinion as it weights quantity a bit higher than quality. Of course this discussion is a big fat sliding scale and I suppose the imperial version is just nice because that’s the only way you can compare yourself to Arthur Eddington.

I’m currently sitting at an imperial EN of 54 (metric 65 FYI). I am confident I’ll make it to 60 by the end of this season (15 rides) without thinking about it. 65 requires 25 rides and 70 would require 33 rides of the correct distances respectively. 70 might be reachable but would require that I’m careful not to log too many between 60 and 70 miles, gotta make them all count!

As this is obviously a lifelong kind of game and not for a single season… then it would make sense for me to keep chipping away at the number of rides I put in above 100 miles as that would quite obviously be a cause for some celebration quite a few years down the road. It’s only 82 rides away! Plus they all count for these lower scores (60-70) as well which is nice.
