The Eddington Number is a strangely addictive score for cyclists, devised by British astrophysicist Arthur Eddington for ranking their achievements in an ever-harder scale. Also known as the Eddington Scale, it is defined as "the largest integer E, where you have cycled at least E miles on at least E days (source: triathlete-europe.competitor.com). It not only gives you a nice number that you can show off to your mates, it also comes with clear progression targets for you to achieve ever-higher Eddington numbers. In other words, "how many more days riding of at least x miles do I ride to achieve that score?" Clever, eh?
It doesn't just work for cyclists; runners and swimmers can also apply the scale. The problem is that it's a little bit tricky to calculate your number, as you need to sort all your rides by distance, then bucket them up appropriately. The key to an accurate number is keeping a good record of your activities. An awful lot of people use Strava nowadays, and on that note I've produced a little tool that analyses all of your Strava rides, calculates your Eddington Number, and shows how many more rides you'll need to increase it. So, head over to "My Strava Eddington Number" page, and see what number you get!
For the record, as of September 10 2020 my number is 110 (it was 90 in October 2017, and 54 in September 2015), and I'm slowly inching towards my new target of 125. I need 34 more 125-mile days to achieve that, so it's in sight. I'm also starting to do more 150-mile rides, as that will be my lifetime target.
Each tab shows the count of Eddington numbers recorded on the My Strava Eddington Number page, so we can get an idea of what are the more common ones.
