Col de Toses (Collada de Toses) — 3D Climb Profile & Gear Ratios

How to use the map

Plan — the climb laid out on a 2D map, drag the slider under the map to travel along it.
3D View — the same route over real 3D elevation data.
Wedge — a side-on profile of the climb, showing gradient as a rising wedge.
Whichever view is open, dragging the slider moves you along the climb — the gradient, distance and elevation readouts on the right update live as you go.
Smoothing (bottom-right of the map) — averages the gradient colour band over a distance window from 0 (off) up to 1000m, so noisy raw gradient data reads as a cleaner gradient.

How to use Setup & Gears

Setup — enter your groupset, weight, power and cadence. This is the same setup used across the Gear Calculator, Climb Planner and Comparator, so it carries over automatically.
Gears — shows which of your gears are achievable at the current gradient as you drag the slider on the map, and flags the ones that are too hard or too easy.
Switch to Setup first if you haven't entered a groupset yet — Gears needs it to work out achievability.
