There will be plastic pop-up bins provided at all the check points for your water bottles, GU Gel packs, High 5 Gel packs and wrappers to be discarded. We would urge you not to discard any litter on the Thames Path trail at all please, our marshals will take any litter from you so just keep it until you get to a marshal, or use the bins provided which will be at each of the 3 check point locations.
