I like running longer runs (e.g. half marathons), but after 15-17 km I ofter need some sort of energizer apart from the water you get along the route.
The question is then what exactly to take, as there seems to several different sorts of energizers available.
I know about gels and energy drinks, but unfortunately these often requires that your drink a lot of water at the same time. I have heard about some fruit gums (e.g. from Squeezy), but haven't tried these yet.
But what is the best source of renewed energy on these longer runs?
