The French Hiking Association also offers a tool that analyses your saved trails (from GPS data) and allows you to calculate the effort rating of a route using an IBP.
Please note, as stated on the IBP index page:
"The IBP index is a system that automatically analyses the level of difficulty of a mountain or road bike route, hiking or running trail. This index is very useful for comparing the level of difficulty of different trails. It's important not to confuse a route's level of difficulty with the physical effort required: a route with an IBP index of 60 will be very difficult for someone with no experience, pretty normal for someone with moderate training, and very easy for a professional."
