Strava Club Annual Leaderboard is a Chrome extension developed by paluchj28. This free extension enhances the functionality of the Strava club leaderboard page by adding an additional annual summary. With this extension, users can compare their achievements not only for the current or past week, but also for the entire year and the previous year. Additionally, users have the option to generate leaderboards for custom weeks.

It is important to note that the values for the leaderboard are calculated from past weeks' leaderboards. This means that complete weeks are included in the summary. For example, if a week of the year 2020 started on December 30th, 2019, the summary will cover the period from December 30th, 2019 to January 3rd, 2020.

However, users should exercise caution when using this extension for clubs with more than 100 members, as it may not show proper data in such cases. Overall, Strava Club Annual Leaderboard is a useful tool for Strava users who want to track and compare their achievements over a longer time period.
