10-Week Climbing Plan: Build Power-to-Weight Endurance for Real Roads

For road riders who want to stop surviving climbs and start controlling them. Climbing performance comes down to two things: sustainable power at threshold and the efficiency to hold it longer than feels reasonable. This plan builds both over ten weeks through sustained threshold work — intervals stay in the 20 to 30-minute range rather than short repeats, because the goal is to extend what you can hold, not sharpen a sprint. Cadence work is integrated throughout every week because low-cadence grinding is the single most common efficiency leak climbers have. Four sessions per week: two Zone 2 rides, one threshold session, one longer weekend ride. A power meter is strongly recommended for accurate pacing on threshold efforts.
