Key Session 2 β€” Saturday Long Ride
Wk 1 (Jul 4): 4–4.5 hrs endurance. Include two separate 20–25 min efforts at tempo pace (80–85% FTP), spaced by at least 20 min easy riding between them.

Wk 2 (Jul 11): Pescadero Road Race β€” race effort replaces long ride this week.

Wk 3 (Jul 18): 4.5 hrs endurance. After 90 min easy, do a single 30 min push at 95–100% FTP on a climb or flat β€” treat it as a standalone hard effort mid-ride.

Wk 4 (Jul 25, recovery): 3 hrs easy, no structured effort.

Wk 2 (Aug 4) β€” KEY SESSION: 5 hrs total. After 60–90 min easy warmup, do 2Γ—30 min at 95% FTP with 6 min rest between. This is the hardest session in the plan β€” bail to 92% if needed. Remainder of ride easy. 242–247W

Wk 3 (Aug 11): 5 hrs endurance. Include one 40 min block at 85–90% FTP in the final third of the ride β€” full fatigue load. Race durability simulator. 217–234W

Key Session 2 β€” Saturday Long Ride
Aug 30: 4.5 hrs. Variable effort on climbs β€” go hard on steep sections (108–115% FTP), settle to tempo on flatter gradient. Mimics drafting surges. No fixed intervals, ride by feel and gradient.

Sep 6: 4.5 hrs. Race sim day β€” ride easy for 90 min, then do two back-to-back 20–25 min climb efforts at goal race pace with minimal rest between. Closest thing to race day you'll do. 252–258W

Sep 13: 4 hrs easy endurance, one 20 min tempo effort only. Legs should feel fresh.

Sep 20: 3 hrs easy. One 20 min tempo effort, nothing more. Taper starts here mentally.

Final Week
SEP 22 – OCT 4  Β·  1 WEEK + RACE DAY  Β·  ~10 HRS  Β·  TSS ~550
Mon–Thu  Sep 22–25
Normal training volume, no heroics. Two rides of 2–2.5 hrs each. One session with 3Γ—8 min at 100% FTP to stay sharp β€” this is not a hard week, just maintaining feel. 263–267W
Fri–Sun  Sep 26–Oct 4
Saturday Sep 27: 3.5 hrs endurance with two 15 min tempo efforts. Last proper ride.

Thu/Fri Oct 2–3: One short 45–60 min opener with 3Γ—3 min at race pace. Spin the legs out, nothing more. 252–258W

Legs should feel restless by Friday evening β€” that's the sign you're ready.

Strength Training
At-Home Strength
JUN 9 – JUL 27  Β·  DROP AT BUILD 2 ONSET  Β·  DUMBBELLS 10–50 LB
2Γ— PER WEEK
~30–35 MIN/SESSION
The Workout
Bulgarian split squat Rear foot elevated on a chair or couch. Hold one dumbbell in each hand. Start at 20–25 lb each, build toward 35–40 lb by week 6.
3Γ—8 each leg  Β·  90 sec rest
Single-leg Romanian deadlift Hold one 30–40 lb dumbbell in the opposite hand. Slow eccentric (3 sec down). Builds hip stability and posterior chain without the recovery cost of a bilateral deadlift.
3Γ—8 each leg  Β·  60 sec rest
Push-ups You're at 5 reps β€” do 3 sets to near failure (not quite failure). Add 1 rep per session when you can. At 15+ reps, add a dumbbell plate on your back or elevate your feet.
3Γ— to near failure  Β·  60 sec rest
Copenhagen plank Side plank with top foot on a chair or couch, bottom leg hanging. Start with 3Γ—10 sec holds, build to 3Γ—20 sec.
3Γ—10–20 sec each side
Dead bug Core stability without spinal load. Slow and controlled β€” opposite arm and leg extend fully while lower back stays flat. 3Γ—8 each side.
3Γ—8 each side  Β·  45 sec rest
Timing & Notes
Start: Jun 9, alongside Rebuild phase.

Frequency: 2Γ— per week. Each session is 30–35 min if you move efficiently between exercises.

Schedule on: Easy riding days only. Never the day before or after a key cycling session.

Drop at: Jul 28 (Build 2 onset). When TSS hits 700–750, the recovery cost outweighs the benefit. Two months of consistent work will hold through October without maintaining it.

On the split squats: Single-leg work will feel humbling at first β€” start at 20 lb per hand and prioritize depth and control over load. You'll progress fast.

Race Day Strategy
October 4, 2026
First 15 min
248–252W
Conservative start regardless of how good you feel. Adrenaline will push you to go out 5–10W hot β€” resist it.
Middle 30 min
255–260W
Settle into goal race pace once you have a read on your legs and the field around you.
Final 15 min
260W+
If you have gas left, open it up. This is what all the variable effort work was building toward.
Variable gradient sections: Where you can draft, back off to 230–240W and recover actively. Match the surge when it comes β€” don't chase every attack in the first half. The riders who go out hard on the steep early pitches are the ones you'll pass in the final 20 minutes.
