I rode it three times in day this year from each side. Its tough and as others have said the weather plays it part. You will be fine and its a really enjoyable ride. Just set out early and take it at your own pace. If you get the chance read up on the Gorge De Nesque (sorry if spelt wrong) route that circles the mountain. Its a stunning ride that should not be missed if you are staying in the area.
Enjoy
