Can anyone point me in the right direction for information! Up until now, my longest run has been 11k. I have only taken on a small amount of water on a couple of very warm days and don't usually carry water with me. However, now I want to increase my distance for a 10 mile event in October, I guess fuel and adequate hydration will become more of an issue (especially as we move in to the summer). I don't know where to begin and there seems to be a lot of, sometimes conflicting advise out there😮. Do I need to start learning about electrolytes etc?
