Bring your own water for the run

It makes the hares life more difficult if they have to decide before the run how much water they have to carry to the start to give away to an as yet unknown number of runners

Bring your own water - sorta like you bring your own shoes and torch and batteries

Most of the water gets chucked away after the run anyway - unopened plastic bottles of Swire Coca-Cola HK's finest into landfill
