Not the route I had originally planned (the weather forecasts were wrong) but I found and followed the blue sky which took me on some back roads between Aix and Salon-de-Provence. Midday pause for worshipping the Sun God at his highest point in the sky; then a picnic lunch: tart of apple slices with a go-faster coffee. Back to Marseille enjoying the little roads around the Étang de Berre.
