I currently run with nothing other than a door key - no food or drink. But I understand that to run further I should think about fuel. If I want to get up to 15k how much of what should I take with me? I think others have indicated that i should be having something every 5k and I know some of you use jelly babies. Is this one jelly baby every 5k? I am just worrying about carrying stuff with me.
As a side note I am coeliac and lactose intolerant so not keen on the gels I see for sale in shops as they appear to be packed full of stuff I have to avoid.
