I have already done a 100, I suppose that counts. Got a 200 DIY planned for July. We are going to do the route that we were doing when I crashed. Not sure if I should use a detour to avoid the corner where I crashed though.
I think a detour would be overkill, but slowing down a bit would be wise
Seriously now, when I had my car crash (many years ago) I was utterly freaked out by similar conditions/corners for months. Driving round the same corner without incident did me a power of good*, so I'd recommend it.
(*although it was quite a disturbing experience)
