Yes indeed, there are several water stations but some of them are quite a distance from each other – not necessarily in kilometers but in time. We are convinced that you will need water along the way and that only hydrating yourself in the water stations will surely be insufficient for a good performance. You can quench your thirst in the water stations and fill up your bottle or hydration bladder as well.
Do notice that NONE of the drink stations will supply drinks in bottles or in cups. Hence it is very important that you bring your own bottle in order to refill it at the drink stations.
