Have a URL field in the session...
If it is a race, you can put an URL to the official Race Results...
or if its a group ride, and someone on the ride, posted the route on-line, it may be handy to have the URL, so you can follow the link.
More advanced version of this, would be offer a button to publish the contents of "notes" to Blogspot, or Twitter, or Facebook.....so if the session notes happened to be a "ride-report" type content...you can 1-click publish to forum's you might want to ...e.g. your own blog....or a Local Riding Club Forums...etc....
