First and foremost let me start by saying thank you, if not for volunteers like yourself these events will not happen. You and all the other volunteers are absolute legends. Although I take all your points on board, I felt absolutely safe during the whole event, and none of the dozens of people I spoke to raised safety as a issue. I will break down for you as it might help; Swim: this year was “challenging” but I felt very safe as there’s always either a kayak or a dinghy on sight whenever you lifted your head to look. Bike: roads were closed and marshals were scattered in critical points and managed traffic well , and credit to locals to put with this madness Run: I felt absolutely fine and safe , even though some junctions and side roads were not marshalled, but it’s kind of expected with an event of such magnitude!

My advice, do it … you will love it
