The share button on the upper right corner of the Activity Detail/Analysis page allows you to share a snapshot of your completed workout, including customized selection of stats and ride graph.

The share image will depict your current graph, so any selection of the graph, selected intervals, or custom options will be shown in the image as they are at the time you click the share button. Up to 6 metrics can be added to the summary and adjusted from the "Choose Fields" menu. Use the name, comment, and color fields to add additional custom options to your activity snapshot. 

The activity snapshot can be shared on Facebook, Twitter, or downloaded as a .JPG to be shared elsewhere.
