This widget shows your latest activities from <a href="https://runkeeper.com/" rel="nofollow ugc">Runkeeper</a>. The number of activities can be configured, as can the values that are being displayed (distance, speed, duration, calories burned). The widget may also be called using the [runkeeper] shortcode.
A little bit of effort is required to set it up, but it’s worth it, because this way, no third party will ever get access to your data. Everything stays between your WordPress site and Runkeeper.
