The two best examples I saw on my recent camino of Europeans splitting up the route were as follows:
A lady from Latvia in her early thirties with three children, the youngest only two years old, who had left her children with her husband and mother-in-law for two weeks while she walked a section of the camino, intending to come back some time in the future to finish at Compostela. On the morning she left to fly back home, I asked when did she expect to return and finish her walk. "In 15 years, when my youngest is 17," was her reply.
A couple from Switzerland, who had started walking from Geneva. They walked an average of 4oo km each year. This year was the final stretch, and after 10 years and 4000 km, they made it to Compostela. I saw them in the cathedral, and didn't they look p;eased. As you would.
Buen Camino
