Leg 01 · The canyon
Sea level to the first summit
The corridor leaves the Fraser delta flat and stays flat exactly as far as Hope — then the valley ends like a door closing and the road starts paying for every metre of altitude. The Coquihalla climbs hardest and arrives first; the older canyon highway trades grade for distance. Which legs a given run uses is a conditions decision made on the day, which is why this brief publishes an approximate distance and no lane promise — the mountain, not the map, gets the final word.
