My Strava Eddington Number

To get started:

The Eddington Number is the greatest number of days that you've ridden that distance. So, if you've managed 30 or more 30-mile days, then your number is 30. If you've only managed 20 or more 20-mile days, then your score is 20. It's an interesting self-improvement statistic, but is quite difficult to calculate - so here is a Strava-based tool that does it for you!
Need more background information? Read more about the Eddington Number, plus some all-athlete charts.

You can now see a breakdown of your Eddington number within each year, seeing how it increases month by month!

For me the Strava connection is broken. Worked 2 weeks ago. I have disconnected and reconnected to Strava and no data shows up.

A software upgrade stopped sessions working properly, so we were losing your connection info. It should be fixed now though!

Nice tool, but the metric preference does not work consistently. For example clicking on a specific year still shows stats in miles. Considering that most of world use the metric system I think fixing this would be nice! Thanks!

Thanks for pointing this out, Riccardo. It should work correctly now!

If I've ridden 79 centuries shouldn't I need to ride 21 more to get a E of 100? My latest update says 19. I am misunderstanding something? Many thanks.

Hi Mike, the reason for this is because of the multi-day rides that you've done. For the purposes of the Eddington number these get split up into an estimated number of miles for each day. Well done with your big miles!

What a great little tool !

Thanks a lot for this.

The buttons for virtual/walk/run show various values but, when clicked on, do not render in the same way as the 'ride' button

Hello Robert, there was a bug in the url for switching between activity types - should be fixed now!

Hi John,

Love your work! I noticed that some of my runs in 2019 were not picked up, especially in the second half. Everything else seems fine (from 2011 to 2020). It's just a few months in 2019 that seem troublesome.

Hi Pedro! Glad you're enjoying it :)

I suspect that your missing runs may not be public. Alternatively the activity-fetching may have gone wrong. Either way, you'll need to re-fetch your activities again; see the info in the "Help" link at the top left of this page.

Hi John,

For some reason, looks like my Eddington is stuck on miles, even though the preference is showing Kms.

Tried to press the Update button and also so a refresh, but no go.

Hi Carl, yes this is a bit confusing! For now you can click the "switch to metric" link (one of the bullet points below the list of targets). I'll look at making metric the default if that's your chosen preference.

Hi John,

I just discovered this page and it's very interesting! But, setting a "Distance preference" to "km" I'm still getting E-numbers in left column in imperial, not in metric. At least, "Metric Ride Eddington Number" and "Ride Hour Record" as well. Or am I missing something?

Ah, I just fixed a mistake in the display of the metric Eddington number - so you should see the correct stat there now!

Hi

Is there somewhere you can add rides that were not on Strava from a while ago? Ive got 9 on Strava of 100 mile plus but have another 15 in history.

You can add rides manually to Strava, no matter how long ago they were. After you've done that, head back over here and see if the rides have been added. If not, you may need to re-fetch your activities from scratch. Note that the rides must be publicly viewable for them to be included here.

Hi John, is the Help Guide link broken? I get 'about:blank#blocked' when I try to follow it. Kind regards Malcolm

Hi. My eddington number is 64 but if I do a search of rides over 64 it only shows 58 I have disconnected and started again but the same.

It says I need 3 more rides to get to 66 but says I have only done 59 at 66 miles.

Thanks though it's a great site.

Hi Allen, I've put together a more detailed "Help Guide" (see the link near the top of this page) which covers common issues. Please check through it and let me know how you get on!

Hi.

My stats seemed to have frozen at October 2019, with an error code of Strava Authorisation.

Checked my Strava privacy settings and they are set at everyone.

Did a reset from scratch and have lost all data now.

Can you help?

Thanks

Gordon

Hi Gordon, the solution is to click "disconnect" at the top left of this page, then to go to your list of apps on Strava and remove swinny.net, then come back here and try to connect again.

It would be interesting to have a multisport Eddington number. For triathletes, there are plenty of Brick workouts

That's a neat idea. Without over-complicating it (eg, by choosing activity types), we could have an all-activity Eddington number. Does that sound sufficient?

Could there be a miscalculation when switching to metric?

My imperial nr is 69, that is equivalent to 112km.

However, my metric eddington nr is 98, and although i rode several 100km rides since my promotion, the eddingtonnr didn't change.

I do understand the difference between 69 times 69 miles vs 112 times 112 km's, that's probably the answer?

by John Swindells on 17 May 2020
Hi Johan, I've been looking at your Strava activities that my site has access to, and there are only 97 rides of 100km or more. (You can see them on my Strava Activity Analyser page.) If you know you've done more than that, maybe they're not set to "public"?

Great app, thanks for your contribution to the cycling community!

For clarity, if I upload to Strava 2 rides for the same day, a morning commute and an afternoon commute, does your app pick this up and sum them to achieve daily mileage? Sorry if it's a dumb question, and I'm sure the answer is obvious...

Second question is what happens when a ride starts one day, and finishes the next?

Thanks!

Mark

Hi Mark, thanks for your comments - much appreciated :)

If you do two or more rides in a day, they get added together to count for the day's total miles. So daily mileage is determined by all the activities in each day.

As for a multi-day ride, the mileage is chopped up according to what time proportion of the ride each day accounts for. This isn't exact of course (as you might slow down into the next day, for example), but is a reasonably approximation without getting into detailed GPX analysis.

There are a couple Strava plugins that'll update your ride description with the weather or similar info after you save it. Any chance that you can look into adding a "New Eddington number = x" or something tag if that day's ride ups my E#?

I don't always think to come check after I have a long day, and I think it'd help popularize the idea of the Eddington number as well.

Hey that's a great idea! I'll look into it, but it would probably be fairly straightforward.

Hi John,

I've clicked the orange Connect to Strava button and it shows on the list of authorized apps on the Strava site, but every time I return to the Eddington number page the orange Connect button is still there, and there isn't a number. Am I doing something wrong?

Hi, that's very odd - you're doing it right! Try refreshing/reloading this page, to see if it triggers a fresh page load.

I had a bunch of activities on a different app. I just uploaded them to Strava. But I still don't see them here. What is the way to trigger a "pull" so these numbers get updated?

Hi, you can use the "refresh the score from scratch" link near the top of this page.

I like looking back at my 100 mile rides on strava but they take a long time to find on IOS.

Is there a function that could pull all the 100milers out to view on here

Thanks

Sounds like you want to use the activity analyser. You can use that to browse and filter your activities by type, distance, year, etc.

Hi John. Is there any chance of showing how many more days you need to do to get to the next few E numbers per year like you do for all time? It is only really needed for the current year but it might be nice to see how far off you were in previous years of getting a better one. My example: coming up to the end of 2019 I have an E number of 43 but I don't have any idea if I need to do just 1 or many more rides to get to 44 before 31st. The breakdown per year only shows what has happened in relation to your current E number.

I might be missing it somewhere else but if not, then I think it could be a nice addition.

Of course I don't expect you to look into this before the end of this year! Thank you very much for all your work on this site. It is really nice to use to track my progress.

Great idea, Jackie; I've just added this for the current year's targets. Does it work ok for you?

Glad you're finding my Strava tools useful :)
