I started in Frick when it was raining, the trails were wet for most of the day. Food: I had enough bars and some gels. Water supply: two flasks 0.5 and 1 liter reserve, which I needed because one flask broke. You can find enough water along the way. I never shortened the route, I walked to the main signposts in Aarau, Baden and Mellingen and back again. It's a very nice route!
