I have a total of 41 walking days and wonder if that is enough for the Via de la Plata from Sevilla. I have walked the Frances several times, and I like to stay in the 24-28 km a day range. I will be starting in early May, and also wonder whether the temperature is likely to be too hot in Andalucia. My other option is to do the Norte, which I think is about 200 km shorter, and thus more do-able. Many thanks for your advice.
