I agree Dave; I test rode the original course solo in the light on Friday. Its too dangerous with quite a sharp ledge on the boards which I think are a blowout waiting to happen, there was also a large gap in two of the boards. This is combined with the narrowing of the road and the need to go on the opposite side twice on the back straight
I think the most reasonable course of action would be to try the smoother route; it will however require a conscious effort to SLOW DOWN and WAIT for any riders at each right turn. The lead rider will need to bear in mind the group behind them and not squeeze out in front of a car; as the rest are likely to follow.
