First 6 or so km were wonderful. Easily 4*. I wore my walking boots, sticks, t-shirt and a technical jacket. Perfect. Just a bit of drizzle But No need for hard shell raincoat.
The pancake and cheese-bar comes quite early so No need to pack too much food. (They close halfway through september).
The rest of the trail is monotonous because of the nature of the path you walk on. You switch to concrete for 2/3 of the hike. That's when you wished you wore sport shoes, Not hiking boots. Sore feet for the Second part of the trip.
Beautiful views all the way. But had to use Some music to eat a few kilometers. Had to switch to raincoat along the way.
