THE FOCUS RIGHT NOW

BUILD THE ENGINE.

Sixteen weeks out, your job is volume. Forget intervals. Forget Strava. Build the aerobic engine that every later phase sits on top of. 80% of your time should be in Zone 2 — conversational pace, nose-breathing territory. If your base phase feels easy, you're doing it right.

THIS WEEK'S ANCHOR SESSION

THE LONG Z2 RIDE

One 3-4 hour steady Zone 2 ride per week. Flat to rolling route. Cadence 85-95rpm. Heart rate below first ventilatory threshold the whole way. This is where your mitochondrial density grows.

THE WEEK

A TYPICAL WEEK, 16 WEEKS OUT

Monday

REST OR 45MIN Z1

Recovery day — coffee spin only if you want to.

Tuesday

90MIN Z2 ENDURANCE

Steady, controlled, aerobic.

Wednesday

1H STRENGTH + 30MIN EASY SPIN

Squats, deadlifts, core. Builds what the bike can't.

Thursday

90MIN Z2 WITH 3X5MIN TEMPO

Intro to structured effort — don't race it.

Friday

REST

Genuine rest. The adaptations happen now.

Saturday

3-4H LONG Z2 RIDE

Anchor session. Fueled from minute 30.

Sunday

90MIN GROUP RIDE OR SOLO Z2

Social pace. No heroes allowed.

DON'T DO THIS

The #1 base-phase mistake: riding too hard on easy days. If you arrive at Saturday already tired, you'll never build the aerobic depth you need. Discipline the volume, discipline the intensity.

EVENT INTEL

WHAT THE GRAN FONDO NYC ACTUALLY DEMANDS

Gran Fondo New York (GFNY) is the flagship USA sportive — 160km from the George Washington Bridge up the Hudson Valley with 2,500m of climbing. Competitive timed format (your position matters), international field, closed bridge at the start.

KEY CHARACTERISTICS

✓Start on the George Washington Bridge — 8,000+ riders
✓Bear Mountain climb — the signature climb at km 90
✓Timed format: results matter, pacing strategies ruthless
✓Rolling Hudson Valley terrain — few flat km
✓May weather: anywhere from 10°C and raining to 30°C and humid

COMMON MISTAKES

✕Burning matches matching pace on the first 30km — it's a race start, not your pace
✕Riding solo instead of working groups — drafting saves 25-30% on the Hudson roads
✕Underfueling because the early rollers feel 'just easy enough'

PACING

Get in a pack at your sportive pace within the first 15km. Work the pack on the flats + rollers. Bear Mountain at km 90 is a 25-30 min threshold effort — attack it at 90-95% FTP if you're chasing a time, 80-85% if you're chasing a finish. The back half rewards steady pacing over heroic climbs.

FUELLING

80-90g carbs/hour. Feed zones at km 55 and km 110 are strategic. Don't skip the km 55 stop. US roadie fuelling culture means everyone carries their own — don't rely on aid station variety.

KIT

Aero road bike with 11-30 cassette. Arm warmers + gilet stashed — weather varies. Rear light mandatory (enforced). Sunglasses with clear lenses for the GW Bridge tunnel at the start.

FAQ

COMMON QUESTIONS AT 16 WEEKS OUT

Is 16 weeks enough to train for the Gran Fondo New York?+

Yes, 16 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 2,500m of climbing over 160km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Gran Fondo New York?+

Start on the George Washington Bridge — 8,000+ riders. burning matches matching pace on the first 30km — it's a race start, not your pace — so pacing discipline is the single biggest lever most amateurs miss. Get in a pack at your sportive pace within the first 15km.

How many hours a week should I train at 16 weeks out from the Gran Fondo New York?+

Aim for 8-12 hours/week if you're targeting a strong finish. The long weekend ride is the anchor (3-4 hours at late base intensities) plus 3-4 structured weekday sessions. Volume matters more than intensity at this phase.

Do I need a coach to train for the Gran Fondo New York?+

You don't need a coach to finish. You do need structure. If you're new to sportives, have a target finish time, have a plateau you can't break, or have a history of peaking wrong, a coached plan pays for itself. Inside Not Done Yet the plan is built backwards from your event date — base, build, peak, taper timed to the week the Gran Fondo New York runs. 7-day free trial, $195/mo.

What gearing should I run for the Gran Fondo New York?+

Aero road bike with 11-30 cassette. Arm warmers + gilet stashed — weather varies. Rear light mandatory (enforced). Sunglasses with clear lenses for the GW Bridge tunnel at the start.
