What changed from the original plan

🚲 Bikes & Range Impact

Rack typeReal-world range/energy impact
Aero roof bars alone (no bikes)Negligible — 2–3%
Roof-mounted bike rack, 2 bikesUp to ~47% more energy at highway speed
Hitch-mounted bike rack, 1–2 bikesUnder 20% extra consumption — the recommended setup
This weekend matters more: you're climbing the Cormet de Roselend (1,968m) and driving mountain roads both days — elevation gain already costs range, and a roof rack stacks that penalty on top. The +15% hitch-rack estimate below already accounts for the mountain driving; a roof rack here could genuinely mean an extra Supercharger stop you wouldn't otherwise need.

Day-by-Day

Thu evening

Meudon-la-Forêt → Lyon

~470 km · low-toll route (A6 to Beaune, ~€22 toll, then free N6) · Beaune Supercharger stop

Bikes on the hitch rack before you leave. Arrive Lyon ~12:30–1am, free night at your friend's.

Fri (remote)

Lyon — no driving

Full remote workday. Top up the battery overnight or at the Bron/Saint-Priest Supercharger before Saturday if you want a full charge for the mountain leg. Free night again — this is the night you save versus the original plan.

Sat

Lyon → Beaufort → Lac de Roselend

~180 km, ~2h with the rack · no charging needed on a full battery

Morning drive up. Visit the Beaufort AOP cheese cooperative for a tasting, then climb to Lac de Roselend — a turquoise 1,557m reservoir on the Route des Grandes Alpes. Walk part of the lakeside trail (full loop ~16 km).

Unsupervised swimming at Roselend is officially prohibited — treat it as a hike/photo stop.
Free overnight: the gravel parking area on the edge of Lac de Roselend is a known, tolerated bivouac spot — no facilities, but a spectacular place to wake up. Paid fallback: Camping Domelin in Beaufort, ~€12/night, has showers.

Sun

Roselend → Cormet de Roselend → Chamonix valley

~90 km · charge at Albertville Supercharger en route

One of the great Alpine drives, over the 1,968m pass. Charge at Albertville (28 stalls, 250kW) on the way through. Ride the flat valley-floor cycle path in Chamonix in the afternoon, then swim at Lac de Passy's supervised zone (12–4pm daily in summer). Wander Chamonix town under Mont Blanc.

Free overnight: Chamonix's municipal aire de service (water/drainage, free) plus the authorized Parking du Cry / Parking du Grépon overnight spots — sleep in the car. Paid fallback: Camping Les Marmottes or Bellevue, ~€22/night, for a proper shower.

Mon (remote)

Chamonix → Yvoire → back to Lyon

~95 km to Yvoire, then ~230 km back to Lyon via Chambéry · charge at Chambéry Supercharger

Work remotely from Chamonix in the morning (solid connectivity). After logging off, drive to Yvoire on Lac Léman — walled medieval village, Blue Flag pebble beach right below the ramparts. Swim, then loop back via Chambéry (Supercharger top-up) to Lyon. Free night at your friend's.

Tue

Lyon → Meudon-la-Forêt

~470 km · free N6 to Beaune, Supercharger stop, then A6 (toll ~€22)

Home for Wednesday.
