The climb factor for a course is the percentage of your energy used in hill-climbing compared
to the energy expended running the flats.
This course has a climb factor of 3% over 3.1 mi, which means that the energy
expenditure for the run is equivalent to running a flat 3.2 mi.

wrote the open source software for it. You can read more about it

The distance or elevation data not precisely
what you expect for this route?
Data from a GPS device can be rough, especially in
areas where the terrain (trees, canyons) interfere
with GPS signals. And routes drawn on our maps are
reliant on people marking trails from satellite
images -- the details of which can be hidden by trees.
Elevation can be tricky too.
Elevation data is stored on spaced topographical
lines, and determining the elevation of a point
requires computers to estimate based on how close the
point is to the topographical line.
We mitigate this by calculating distance in
3-D (think Pythagorean theorem) and using mathematical
techiniques to smooth the elevation data. We come
close, but no one can be perfect with imperfect data,
even in
2026.
