Perhaps this will be The Loop!

I've been spending a lot of time with gmap-pedometer working to devise a 60k loop for the birthday run. This may be the winner. I've run most of it in bits and pieces over the winter - and some bits and pieces many times over the years. I'll be giving a big chunk of it a whirl tomorrow during my last pre-birthday 30-miler. It definitely shows promise!
