Overview

Every recreational cyclist eventually hits the same wall: the climbs don't get easier just by riding more. Adding more Z2 base stops helping past a certain point. What moves the needle from "I can finish the Fred Whitton" to "I can finish the Fred Whitton comfortably" is targeted power work.

This 12-week plan is built around improving three specific numbers: your 1-hour power (FTP), your 5-minute power (VO2), and your power-to-weight ratio on climbs longer than 10 minutes. If you're already comfortable doing structured intervals and know your FTP within 5%, this plan is for you.

Golden Rule: On climbs, your speed is set by watts per kilogram. Either push more watts or carry fewer kilograms. Both work — but ignoring either is leaving time on the road.

Prerequisites

Current FTP known (test within the last 4 weeks)
3+ years of regular cycling, or equivalent fitness from another endurance sport
Comfortable doing 90+ minute rides at Z2
Access to hills (or a smart trainer that simulates gradient via ERG mode)

If any of those don't apply, do the Indoor Cycling & Zwift Training plan first.

Power-to-Weight: What Really Matters on Climbs

Rider FTP	Rider Weight	W/kg	Climbing Ability
200W	80kg	2.5	Recreational
240W	75kg	3.2	Club-strong
280W	70kg	4.0	Strong club, fast sportive
320W	68kg	4.7	Cat 2/3 UK racing
350W	65kg	5.4	Elite amateur / semi-pro

You can improve in two directions: more watts (training) or less weight (body composition). Don't chase weight at the expense of power — under-fuelled training is slower than well-fuelled training with a few extra kilos.

Training Zones Recap

Zone	% FTP	Purpose
Z2	56-75%	Aerobic base
Z3	76-90%	Tempo / Sweet Spot
Z4	91-105%	Threshold (FTP)
Z5	106-120%	VO2 max
Z6	>120%	Anaerobic capacity

Structure of the 12 Weeks

Three 4-week blocks, each progressively more specific. Volume stays roughly constant; intensity distribution shifts.

Block 1 (Weeks 1-4): Threshold Development

Goal: raise FTP by 5-8%.

Day	Session	Power Target
Tue	3×12 min Sweet Spot, 4 min rest	88-92% FTP
Thu	2×20 min at threshold, 5 min rest	95-100% FTP
Sat	Long Z2 ride, 3-4 hours	65-75% FTP
Sun	Recovery spin 45 min	<50% FTP

Every 3 weeks, take a recovery week (reduce volume by 40%, keep one intensity session).

Block 2 (Weeks 5-8): VO2 Max & Top-End

Goal: raise VO2 power, expand the ceiling above FTP.

Day	Session	Power Target
Tue	6×3 min VO2, 3 min rest	110-115% FTP
Thu	Climb repeats — 5×5 min uphill, ride down to recover	105-110% FTP
Sat	Long Z2 with 2×20 min tempo	65-75% / 80-85%
Sun	Recovery spin 45 min	<50% FTP

Climb repeats are the key session. Find a 5-minute climb. Hit it hard. Ride down to recover. Repeat 5 times. If no outdoor climb is available, use a trainer with gradient simulation and pick a Zwift or Rouvy climb.

Block 3 (Weeks 9-12): Climb-Specific & Peak

Goal: stitch the fitness together into race/event form.

Day	Session	Power Target
Tue	Over-unders 5×(2 min @ 105%, 3 min @ 95%), 3 min rest	Zone 4-5
Thu	Long climb reps — 3×10 min at FTP uphill	95-100% FTP
Sat	Event-simulation long ride with goal-climb efforts	Varied
Sun	Recovery spin 45 min	<50% FTP

In Week 12, drop volume 30% but keep one intensity session — that's your taper.

Climbing-Specific Tactics

Cadence on climbs. Most riders default too low. Aim for 75-85 rpm on long climbs — you'll save your legs and can hold higher watts for longer. Low-cadence (60-70 rpm) climbs are a specific training tool, not default mode.

Pacing variable-gradient climbs. On a climb with flats and steep pitches (typical UK lake-district roads), power should stay roughly constant. That means you slow down on the steep bits — don't fight that. Fighting is how you blow up.

Seated vs standing. Seated is more efficient but loads one set of muscles. Standing recruits different muscles and flushes blood. On a 20-minute climb, 30-60 seconds standing every 5 minutes is a useful way to manage fatigue.

Body Composition Without Wrecking Training

If you're carrying an extra 3-5kg that would come off cleanly, a moderate deficit (300-400 kcal/day) during Block 1 works well. Do NOT run a deficit during Block 2 or 3 — VO2 sessions under-fuelled are hollow.

Pre-ride: 50-80g carbs for sessions over 90 minutes
In-ride: 60-90g carbs/hour for sessions over 90 minutes
Post-ride: 1-1.5g protein per kg bodyweight within an hour

FTP Re-test

At the end of Block 1 and Block 3. Not more often — an FTP test is a hard session that costs you 2-3 days of other training.

Common Mistakes

Testing too early. A stale FTP is fine; a tired test result is worthless and sets every session to the wrong targets.
Chasing watts on every ride. Z2 should feel easy. If it doesn't, recovery isn't happening.
Ignoring cadence. Power alone doesn't tell the whole story. A high-watt low-cadence climb burns matches you'll want in the last hour.
Skipping recovery weeks. Every 3-4 weeks of build needs one recovery week. Not optional.

What's Next

After 12 weeks, pick a goal event — Etape du Dales, Fred Whitton, Ride London 100, or a mountain stage on Zwift. Apply this structure each season and your 20-year-older self will still be climbing.
