Twunlog is actually created and managed by someone I know, Yancy Lent, so it was interesting to see the development efforts. He started with a clean UI and oAuth integration to get you moving. From there the homepage has a listing of the current public running activity. It shows over 9100 runners covering an already amazing 108k miles. Adding your own was quite simple:
In the current timeline you see the avatar of the person and the amount of miles (and ghosted below the kilometers) the person ran and the tweet that was picked up. The funny thing is some of them might not even be using the service, Twunlog just picks them up. It will also show the number of runs entered for that person.
Once logged in you can see your history as well as flag any tweets the filter picked up that were not actual runs. Like “I feel like I ran 14 miles” when you sat at your desk.
As more runs are listed you will see more reports and better tracking. A great service for runners trying to keep track. We know you tweet while you run
