On this ride: the part this route climbs, cut from its own elevation profile. Full ascent: the whole named climb, measured the same way on every ride that uses it (its climb page).

A point maximum far steeper than the climb’s average is usually an elevation-data spike, so the steepest 500 m of the profile is shown instead (or nothing, where the profile is too coarse).
