Not sure if anybody has heard of this, but it’s a club in France that you can register for the challenge to ride all 3 side of Mont Ventoux in one day and get a certificate. I did it myself in 2017, a rather hard but enjoyable day.
Anyways they are now offering a virtual challenge of doing all three sides in one day using Rouvy.
I plan to do it tomorrow, info is here for anyone that’s fancies it. Www.clubcinglesventoux.org
