Sign-ups close on Wednesday. Twenty-two places, and eighteen have gone. This one is longer than our usual walks: eighteen kilometres, with a steady climb in the first hour and nothing flat until lunch. If you have only done the river walks with us, please read that sentence again. The coach leaves the union at seven. It will not wait; two people learned this in November. Bring lunch and two litres of water. There is one shop on the route and it closes at eleven. Boots rather than trainers, and a waterproof even if the forecast is good, because the forecast for that stretch of coast is wrong about half the time.
