IANAO either, and this is why.
You and me both. It's a shame because I'd love to put on a 200 and 300 from Chepstow to precede the Brevet Cymru and Bryan Chapman.
The difficulty lies in what to include in a risk assessment, and what a coroner or judge might conclude if a rider's family employ some good lawyers to pursue an organiser in the event of their death or serious injury, which is, unfortunately, likely to happen at some point.
IANAL but it seems to me that organisers have a clear duty of care to their riders. What this means in terms of what should be expected on a routesheet and in a risk assessment remains to be seen, and it will, rather sadly, take a bad accident to find out.
What I do suspect is that hazards that riders will experience on the ride should be explicitly made clear to them, even the bleedin' obvious like hazards presented by other road users, cattle grids, frost and tiredness. I don't think it's good enough to say that riders are taking part in a private excursion on public roads and let them get on with it. They are not; they're taking part in an organised event.
This is why I don't think we should be trying to make Audax appeal to a wider range of cyclists.
Well, mainly: I also want to still be able to get a bunk on the Bryan Chapman if I turn up at 2am!
This is not my understanding of H&S. I work in the construction industry and when you design stuff you have the right to assume (and it is explicitly stated in CDM regulation) that contractors are competent. So in short you can't be blamed for people injuring themselves out of their stupidity but if I do something silly (such as design something instable or expect people to manhandle 80kg bits of kit) and sombody gets hurt then I am in real trouble. I can nevertheless specify stuff with hazards associated to it if I have a good reason documented and I have highlighted to everybody so that they can derisk it.
So in short with my understanding on how H&S works, as an organiser I would flag up only things that would catch people by surprise such as a nasty corner, a
very badly placed MH cover or a dangerous cattle grid. If a genuine hazard make somebody come off one year, I would definitely flag it the next time.
I would expect people to spot bad road surfaces, visible cattle grids, traffic lights roundabouts white vans... Because of the sentence on"arduous routes etc" I would expect people to have sound kit and be reasonably fit.
I would aim to have no more than a few warnings and if challenged why, I would reply that too much information is useless as people don't read it. If I had to write 10 warnings, I would seriously think why and either conclude that the route is not suitable or that I am highlighting hazards that a competent rider would spot. I can't think of an audax route I've ridden which wasn't suitable. There are events though where the organiser could have been in trouble such as LEL when they did not really know how many people were riding which is obviously a big H&S fail, if things go wrong the authorities need to know how many people to look for (a remake of fastnet 79 anybody?)
There is also one important point to remember, IME lawyers mainly pursue where they can smell money and I don't think that Audax UK qualify for their definition of solvability; they are more likely to go after the city council or the Highway agency.
Organiser who really want to cover themselves can write a letter to the relevant city councils highlighting the major hazards they've identified. They can also write a warning on the routesheet saying that they expect participants to be competent riders and only hazards that may catch an experienced rider are highlighted. With such a statement it would be very difficult to blame the organiser for anything trivial and anything major would be passed to the CC/HA.
H&S gets a bad name because too many people use it for their personal agenda but in my experience when done correctly it is not such a burden and I like the idea of sleeping well at night. If somebody were to loose life through my negligence I would be sick of it!
IANAL, and this is no more than a personal opinion. I have never been to court through my negligence nor send any of my previous employers... and this kind of stuff is frequent in the building industry! Touching wood. ;-)
