What It Is

EddingtonMap.com is a niche online tool built specifically for long-distance cycling enthusiasts. It is designed to calculate, track, and visualize a rider’s “Eddington number.” Originally borrowed from the world of physics and later adopted by cyclists, the Eddington number is a hardcore metric representing the number of days on which a rider has ridden at least E miles. For example, an Eddington number of 100 means the rider has completed at least 100 rides of 100 miles or more. Through intuitive data presentation, the site helps users see which rides are actually contributing to improving that number.

Core Features

The site’s core value lies in accurate Eddington number calculation and visualization. It can calculate lifetime, yearly, or weekly Eddington numbers, and uses color highlighting to show which rides “count” and which ones — marked in red — will no longer count after the next increase in the number. For data import, the site supports seamless syncing with the mainstream sports social platform Strava, allowing users to automatically import ride data after authorization. It also provides a manual entry form for users who do not use Strava or who need to add historical ride data.

Pricing

According to the site, the developer clearly states that file uploads are not currently supported due to limited server storage. This suggests that the project is most likely a free, public-interest tool maintained by the developer as a personal passion project. At present, there are no signs of paid subscriptions or commercialization, and it appears to be completely free for users.

Pros and Cons

Pros: 1. Fills a gap in the market for Eddington number calculation tools and is highly specialized; 2. Clever visualization design, with red/green markers making progress easy to understand at a glance; 3. Supports one-click Strava syncing, greatly reducing the friction of data entry.
Cons: 1. Extremely niche, with real value mainly for hardcore riders focused on long-distance cycling metrics; 2. Does not support direct uploads of cycling files such as GPX, limiting data import options; 3. Server resources appear limited, raising questions about future data capacity; 4. Supports miles only, which is not ideal for users accustomed to the metric system.

Who It’s For

Best suited for hardcore cyclists who are passionate about long-distance riding and quantified self-improvement, especially users who already have a Strava account and want to dig deeper into the potential of their ride data. It is of limited use to casual cyclists or people mainly interested in short-distance commuting.

Access from China

The website itself may be directly accessible, but its core login and data-sync features depend heavily on the Strava API. Since Strava is blocked in mainland China, domestic users need to use a proxy to complete account authorization and data syncing. As a result, the actual user experience should be considered “partially restricted.”
