My heart wants to do the Primitivo but my body thinks the Frances from Leon is a better choice. Is it possible to start the Primitivo and if it proves too much to get transportation to Leon to restart? I feel pathetic even asking, but just trying to think through all my options. For a little background, I'm a 57 year old female in decent shape. Knees and hips get a little grumpy if I walk more than 20-24 kilometers, but I've been doing 13 kilometers regularly with no problem training daily..
