Camino de Santiago, The French Way
We are walking from Saint-Jean-Pied-de-Port, but we are not stopping at Santiago de Compostela (769.8km), our end is Finisterre, adding another 86.1k typically 5-6 days, in total 855.9k, (535 miles) but there are options to take more scenic & quieter sections of the pilgrimage & our plan is to explore some of those & extend our route.
Most people walk it in 6 weeks, we are expecting it to take 7 weeks or possibly longer. We love the concept in the states for their much longer Appalachian Trail & Pacific Crest Trail, were most walkers have zeros, days they don't achieve any miles. For the American long distant trails you have to come of trail to restock & it's normal to take one or more zeros. The idea is we are going to do the same, when we pass through somewhere we'd like to explore more, or we feel we need to recharge, we'll take some zero's.
