About the only comment I'd make is Port of london got rid of the london Calais race, Boats screaming up the river through the barrier. Why now has the goal post change to allow another group to go screaming back through the barrier and the port of london. If they have managed it best of luck to them. But I think I'd keep the money in my pocket and see how it goes maybe the following year if you must. Having belted down the thames prepare yourself for damage Have raced along it & at the time it was the practice rumfor me you have lots & lots of debris. think the wost was a telegraph pole, shite loads of pallets, Fridges, ect
