Why bother waiting? Hovis / GG clearly want to organise it, have already gone to the trouble of securing a venue for three possible dates that has everything required to make it a belter. There is a great riding route already thought out that caters for all abilities. It's a no-brainer.
Anyone else who would seriously be interested in organising naything would know about or have seen the proposal thread by now - just declare it done I say.
