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.

WHAT THE FRED WHITTON ACTUALLY DEMANDS

Fred Whitton Challenge is the UK's hardest sportive — 180km through the Lake District with 3,950m of climbing including Hardknott Pass (33% max gradient). A pure climbing test. Finishers consider it a career highlight.

KEY CHARACTERISTICS

✓Hardknott Pass — 33% max gradient, cobbled in places
✓Four 10%+ climbs stacked on top of each other
✓Weather can put visibility at 50m on the summits
✓Cut-off times at checkpoints tight for slower riders
✓Field size smaller than Wicklow or Ride London — less pack riding

COMMON MISTAKES

✕Riding a 50/34 + 11-28 and discovering 33% gradient mid-effort
✕Saving yourself for Hardknott and bonking before it
✕Pushing the descent after the Struggle when the legs are done

PACING

Fred Whitton is about finishing. Heart rate management on the first three climbs is everything. Target Z3 ceiling on Kirkstone, Honister, and Newlands. Save Zone 4 for Wrynose and Hardknott. The last 30km are a drift — pace for survival.

FUELLING

10-12 hours needs 80-100g carbs/hour sustained — that's the difference-maker. Food at every feed zone, don't skip 'because you feel OK'. Electrolytes matter more than calories in the last 60km.

KIT

34x34 minimum gearing. Some riders use a 1x setup. Walking shoes are not weakness — plenty of people walk Hardknott. Long-finger gloves for descents.
