Notes
Note 1: the path length, here calculated using Google Map, may be different
from
that declared by the race organizers. Accept as true the latter.
Note 2: the elevation and slope are estimated again using Google and may differ
from the real ones.
Pay attention to any paths with tunnels or viaducts, because the altitude calculated
by Google is not that
of the road, but rather the land!
Note 3: the slope is found by calculating the change in altitude of at least
150 m (492 ft) long sections.
Level roads: slopes between -3% and +3%. Uphill roads: slopes between +3% and +7%.
Steep hill upwards:
slopes greater than +7%. Similar classification for descents.
