SKC is a Chrome add-on developed by Timo Schinkel that allows amateur cyclists to calculate their "Steven Kruijswijk Coefficient" (SKC) for their Strava rides. This add-on is designed to help cyclists train like the professional rider, Steven Kruijswijk, without the need to send any personal information to a third-party server.

With SKC, cyclists can easily see their SKC on the detail page of a bike ride on the Strava website. This coefficient is calculated based on the user's ride data and provides an indication of their performance compared to Steven Kruijswijk.

SKC is a free add-on available on the Chrome platform, making it easily accessible to Strava users. Whether you're a serious cyclist or simply looking to improve your performance, SKC offers a unique way to track and measure your progress on Strava.
