What do you want for walking? The Fenix would be the best for navigation, but it has a lot of features you won't get the most out of if you don't wear it regularly.
Basically navigation and recording. Fenix looks like it would be good, but very expensive and I'd likely be spending for features that I don't end up using. Wondering if maybe just carrying a cycle computer around in my pocket would be the way to go for the hikes. The watches are pricy.
