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.

EVENT INTEL

WHAT THE RIDE LONDON ACTUALLY DEMANDS

Ride London 100 is the UK's largest mass-participation sportive — 160km (100 miles) from Surrey into central London on closed roads. Rolling with two named climbs (Leith Hill, Box Hill). First-time 100-mile riders dominate the field.

KEY CHARACTERISTICS

✓Closed roads on the outbound and return legs
✓Leith Hill — the psychological midpoint; Box Hill — the fun one
✓Pack riding dominates — drafting saves 20-30% of your work
✓Central London finish with huge crowds
✓Early start (often 06:30) — means late nights the week before ruin you

COMMON MISTAKES

✕Surfing from group to group in the first 40km and burning matches
✕Underhydrating because it 'doesn't feel hot' on closed roads
✕Descending Leith Hill too cautiously and losing the pack behind you

PACING

Sit in a pack at your sportive pace. Don't chase a faster pack if you can't comfortably hold a wheel for 10 minutes. Leith Hill is at 77km — keep your power 10% below threshold. Box Hill is a 3-minute effort, go for a Strava time if you have legs, otherwise spin.

FUELLING

Gels every 30-45 min + bar every 90. Closed-road feed zones are plentiful but often packed — carry enough that you can skip one. Caffeine gel at 100km keeps the focus through the urban section.

KIT

Aero road bike with 52/36 + 11-30 cassette is plenty. No need for climbing gear. Bidon cage warming bottles (it often rains). Thin gloves — finish is in London, traffic after the line.

FAQ

COMMON QUESTIONS AT 12 WEEKS OUT

Is 12 weeks enough to train for the Ride London 100?+

Yes, 12 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 1,200m of climbing over 160km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Ride London 100?+

Closed roads on the outbound and return legs. surfing from group to group in the first 40km and burning matches — so pacing discipline is the single biggest lever most amateurs miss. Sit in a pack at your sportive pace.

How many hours a week should I train at 12 weeks out from the Ride London 100?+

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 Ride London 100?+

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 Ride London 100 runs. 7-day free trial, $195/mo.

What gearing should I run for the Ride London 100?+

Aero road bike with 52/36 + 11-30 cassette is plenty. No need for climbing gear. Bidon cage warming bottles (it often rains). Thin gloves — finish is in London, traffic after the line.
