In modern cycling, organizers are always looking for even more challenging climbs to test the riders’ legs. When the pros don’t seem to be going that fast, you know: it’s too steep.
Amateur cyclists can only (who knows) climb with a Mountain Bike setup. Especially in the Giro and Vuelta, the organization likes to push the limits. However, the Tour de France seems to be gradually following the same path.

In smaller Tours, these steep new challenges are often the test for “the big event”. A Twitter user decided to map these climbs with their steepest sections, check it out below.
