Below are two of the basic Strava widgets one can take from the Strava website. To use such widgets, simply go to your personal page below the stats table that shows your statistics you’ll find a button button that says share runs. The popup shows the following code to embed a widget:

<iframe
 height='160'
 width='300'
 frameborder='0'
 allowtransparency='true'
 scrolling='no'
 src='<personal-strava-url>'
 >
</iframe>

<iframe height='454'
width='300'
frameborder='0'
allowtransparency='true'
scrolling='no'
 src='<personal-strava-url>'

The above snippets, after adding your personal profile url, will result in the widgets below. The personal url is the one given by the code snippets from you presonal java page. Note that only public acitivies are shown.
