Character. The largest hill-climb event in the world by participant numbers. Fujisan Subaru Line ascent from ~1,000 m to 2,305 m over 24 km. A uniquely Japanese amateur cycling institution β thousands of riders, strict wave-start format, mountain-top finish.
Conditions. Early June: 15β25 Β°C at the base, 5β12 Β°C at the summit, possible cloud and light rain at altitude. Cool morning start.
Lube plan
If you wax β ZFC-recommended path. Wear-over-distance barely matters at 24 km. Any Tier 1 immersive wax works perfectly; cost and faff are immaterial for a sub-2-hour effort. Summit drizzle? Tarmac rain is just water β the wax rides through it over 24 km, no point carrying oil. Pick what's already on your race-day chain and ride.
If you're on oil β pragmatic equivalent. Whatever's on the chain is fine β 24 km doesn't accumulate meaningful wear. Apply your usual oil the night before for a clean readout and ride. Friction differences matter slightly here (it's a TT effort), but only at sharp-end finishing positions.
