THE FOCUS RIGHT NOW

BUILD THE ENGINE.

Twelve weeks out, you're still building the base — but specific structure is starting to appear. Tempo work enters the picture one day a week. Long rides get longer. This is where the event-specific fitness starts to take shape without compromising your aerobic foundation.

THIS WEEK'S ANCHOR SESSION

TEMPO SANDWICH

2x20min at tempo (76-88% FTP) inside a 2-hour Z2 ride. Steady, controlled, not a time trial. This is your first taste of extended race-pace efforts.

DON'T DO THIS

Don't start threshold intervals yet. The build phase will come. If you jump intensity too early you'll peak 6 weeks before race day and arrive flat.

EVENT INTEL

WHAT THE TOUR OF FLANDERS ACTUALLY DEMANDS

The Ronde van Vlaanderen Cyclo is the amateur Tour of Flanders — ridden the day before the pros, on the same roads, finishing in Oudenaarde. The long route is 229km with around 2,600m of climbing across seventeen hellingen, most of them cobbled, including the Koppenberg, the Oude Kwaremont and the Paterberg. The elevation total undersells the day: this is repeated short, violent climbs on stones, not long Alpine cols.

KEY CHARACTERISTICS

  • Seventeen short bergs — Koppenberg (22% max), Paterberg (20% max), Oude Kwaremont — most under a kilometre but savagely steep
  • Cobbled climbs and cobbled flat sectors that punish anyone who can't hold a wheel or a line
  • Open Flandrian farmland means crosswinds and echelons — positioning matters as much as watts
  • Four distances (75 / 130 / 177 / 229km) — pick the one that matches your spring fitness
  • Early-April weather: cold, wind, frequent rain, and greasy cobbles

COMMON MISTAKES

  • Training for steady power when the day is decided by 30-90 second max efforts on each berg
  • Hitting the Koppenberg in the wrong gear and getting forced to walk in a clipped-out conga line
  • Treating the cobbles as a fitness problem — it's a bike-handling and tyre-pressure problem first

PACING

Flanders isn't paced like a sportive, it's paced like a series of sprints with long recoveries between them. The bergs come in clusters in the back half — Koppenberg, then Taaienberg, then the Oude Kwaremont–Paterberg one-two near the finish. Each is a 30-90 second effort well over threshold. The skill is recovering on the flat, arriving at the base of each climb near the front, in the right gear, carrying momentum onto the stones. Burn your matches surging for position in the first 100km and you'll be walking the Koppenberg with the day still in front of you.

FUELLING

A cold 8-12 hour day burns more than riders expect, and appetite drops in the cold, so you eat on a timer or not at all. Target 60-90g carbs/hour, front-loaded into the first half before the bergs come thick and fast — you cannot eat mid-cobble. Use the feed zones for real food and a warm drink; Flandrian classics culture runs on rice cake and waffle, not just gels. Insulate one bottle enough that you'll actually drink from it in April.

KIT

Tyre choice and pressure decide your day on the cobbles: 28-30mm run softer than you would on tarmac, tubeless if you have it. Compact gearing (34x30 minimum) for the Koppenberg's 22% ramp on wet stone. Pack a rain shell, full-finger gloves and a cap under the helmet — April in Flanders is genuinely cold and wet. Cushioned bar tape, or doubled-up tape, saves your hands across 35km+ of pavé.

FAQ

COMMON QUESTIONS AT 12 WEEKS OUT

Is 12 weeks enough to train for the Tour of Flanders Cyclo (Ronde van Vlaanderen)?+

Yes, 12 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 2,600m of climbing over 229km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Tour of Flanders Cyclo (Ronde van Vlaanderen)?+

Seventeen short bergs — Koppenberg (22% max), Paterberg (20% max), Oude Kwaremont — most under a kilometre but savagely steep. training for steady power when the day is decided by 30-90 second max efforts on each berg — so pacing discipline is the single biggest lever most amateurs miss. Flanders isn't paced like a sportive, it's paced like a series of sprints with long recoveries between them.

How many hours a week should I train at 12 weeks out from the Tour of Flanders Cyclo (Ronde van Vlaanderen)?+

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

Do I need a coach to train for the Tour of Flanders Cyclo (Ronde van Vlaanderen)?+

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 the Not Done Yet coaching community the plan is built backwards from your event date — base, build, peak, taper timed to the week the Tour of Flanders Cyclo (Ronde van Vlaanderen) runs. 7-day free trial, $195/mo.

What gearing should I run for the Tour of Flanders Cyclo (Ronde van Vlaanderen)?+

Tyre choice and pressure decide your day on the cobbles: 28-30mm run softer than you would on tarmac, tubeless if you have it. Compact gearing (34x30 minimum) for the Koppenberg's 22% ramp on wet stone. Pack a rain shell, full-finger gloves and a cap under the helmet — April in Flanders is genuinely cold and wet. Cushioned bar tape, or doubled-up tape, saves your hands across 35km+ of pavé.
