Hi I'm planning to climb Snowdon soon and I have most of my kit already, still a few bits to buy but I'm generally sorted. My big question is food, I estimate that it'll take 2.5 hours up the mountain and same again down so I don't need to pack for war but I have no idea of how much/what type of food to take. What is a good idea to take in terms of food? Any advice will be appreciated.
