How about walking a bit before Zandvoort walkathon?! My idea is to start from the bus stop "Waterleiding/Nieuw Unicum" in Zandvoort and follow the route called "LAW 5-2 Hollands Kustpad" until we reach the beach at the street Langevelderslag, Noordwijk. Then we could continue along the beach all the way to Zandvoort or in case of very strong wind we could hide and pass through Amsterdamse Waterleiding and go to Zandvoort. The route is around 20km but I am planning to walk on a slow pace. 20km is an optimistic plan. In case of nasty weather there are plenty of possible shortcuts on the way, so we can be flexible. Anybody up?
