The Runkeeper Fitness Feed adds a widget which displays up to your last 20 activities.
Works great for me. I had to make a few changes to suit my needs, though.
I converted to miles (I'm American), added pace (my widget only renders in medium), and removed the activity type (I only use runkeeper to track runs).
If you'd like to see my changes, I've hosted them here:
Unfortunately, the line endings resulted in every line appearing to be modified. If you download both versions of the files I edited and diff them with the -b (ignore whitespace) switch, you'll get a better idea what I did (a total hack job).
Thanks for contributing!
