I personally dont think its that bad. Its not long or especially steep, certainly compared to alpine hills. Having said that alot of the Lakes passes are only steep for short sections Winnats is pretty much the same grade from top to bottom.
I dont even think the bottom is that bad, plenty of places to run on to the grass etc
Unfortunately what happened was an accident, and I dont think anyone on this forum knows what happened. She might have stopped at the bottom and not managed to unclip for all we know and got a head injury.
Its a safe road, as safe as any other as far as I am concerned, unless some one can statistically prove other wise?
