I ran a marathon recently with a belt, carrying 2 0.5l bottles + power gels, jelly babies & 2 x .25l bottles of water etc....a wide belt, fully adjsutable and not bother. I got this from Blacks...very cheap, no nonsense. I find the trendy sports belts do not carry enough fluid, and when you train in the wilds of Donegal, you carry your own + your phone etc !
