THE FOCUS RIGHT NOW

BUILD THE INTENSITY.

Eight weeks out, the build phase kicks in. One threshold session, one VO2 max session, and the long ride all in a week. Volume stays high, but now intensity layers on top. This is where your FTP should start climbing — if it doesn't, distribution is wrong, not effort.

THIS WEEK'S ANCHOR SESSION

2X20MIN THRESHOLD

Warm up 15min. 2x20min at 91-105% FTP with 5min recovery between. Cool down. Hit the target power both reps — if you fade the second, you started too hard. This is your bread-and-butter threshold session.

THE WEEK

A TYPICAL WEEK, 8 WEEKS OUT

Monday

REST

Recovery is a session — treat it like one.

Tuesday

THRESHOLD INTERVALS (2X20MIN)

Your key quality session of the week.

Wednesday

90MIN Z2 + STRENGTH

Reduced gym volume — maintenance only.

Thursday

VO2 MAX (4X4MIN @ 106-120% FTP)

Push the ceiling. Rep 4 should be the hardest.

Friday

REST OR 45MIN RECOVERY

Legs up.

Saturday

4-6H LONG RIDE WITH 3X15MIN AT EVENT PACE

Specificity starts here.

Sunday

2H Z2

Active recovery.

DON'T DO THIS

Do not stack threshold and VO2 max back-to-back. 48 hours minimum between quality sessions. Stacking kills the adaptation and makes you fragile.

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 8 WEEKS OUT

Is 8 weeks enough to train for the Ride London 100?+

Yes, if you already have a reasonable aerobic base. 8 weeks out means peak and taper — we can sharpen and refine, but we can't build new aerobic fitness from scratch. If you're starting from zero now, aim for finishing rather than personal bests.

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 8 weeks out from the Ride London 100?+

Reduce to 8-10 hours with rising intensity quality. This is the peak phase — fewer, sharper sessions. Long weekend ride stays but drops slightly (3-4 hours with event-specific work). Weekday sessions are shorter and more intense.

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.
