Leave Pamplona 05:00 · Rotterdam 19:21
1 317 km · 12 h 56 driving (Waze) · 1 h 25 stopped
Seeded figures follow your edits; the explanations below do not. Driving time is Waze's own estimate for this line (12 h 56, quoted 4 Nov 2026), a free-flow-ish figure: the day's traffic can add 30–60 min. Arrival band 18:50–20:00, and it assumes the Paris line below. Pamplona is a city-centre placeholder; Rotterdam is the Centrum placeholder (±10 km / ±10 min against your real door).
Repsol Comete Sarea 1, Behobia, Irun · 24 h · 95 E5 €1.809/L (MITECO feed, 03/11/2026) · 43.33853, -1.75369. Km 93 assumes the AP-8 / A-15 motorway line, not the N-121-A mountain road. Arrive ~05:55, 15 min, leave ~06:10.
Why Repsol and not the cheaper one: Bidasoil Behobia (43.33581, -1.75271, €1.689) opens 07:00 on Sunday, so it is shut at 06:10. Use Bidasoil only if you leave later than 07:05. Dog: grass 53 m, forest 81 m, lead on. Pay at the counter if the pump refuses a foreign card.
Skipping the stop: if you would rather not stop at all, fill at Petroprix Berrioplano (42.83367, -1.65231, 24 h, €1.619) before leaving — but then leg 1 runs 5 h 48 and breaks the 4–5 h rule.
A10 → A86 → A3 → A1, 1 317 km / 12 h 56 driving (Waze), crossing the Île-de-France on the inner ring, never the Boulevard Périphérique (the périphérique variant is the same distance and 19 min slower). You enter the Île-de-France about 13:20 and are on the A1 by ~13:50; target the crossing at 13:00–14:30.
You asked for the shortest total time unless Paris is needed. The Paris bypass is not free, so the answer is: it is needed.
The bypass — A10 → A28 Rouen → A29 Amiens → A1 — is 1 434 km: +117 km and +1 h 42. Free-flow figures, OSRM, 3 Nov 2026. The Paris crossing would have to run more than ~1 h 40 slower than free-flow to lose that margin.
Stops: three — the Spain fill at Behobia (km 93, ~05:55, 15 min), Poitiers-Chincé (km 551, ~10:40, 35 min, fuel + lunch) and Assevillers (km 1 003, ~15:41, 35 min, fuel + break). Drive legs 0 h 55 · 4 h 30 · 4 h 26 · 3 h 05, 12 h 56 driving + 1 h 25 stopped = 14 h 21 elapsed. The two middle legs sit inside your 4–5 h band; leg 1 is 55 min because it is the border fill, not a break leg, and the last is 3 h 05 because the trip ends.
The losing option: a 17:30 start puts Paris at 03:30 — no measurable time saved, 14 h of night driving with a dog. Not recommended.

Three fills: Behobia (Spain, Repsol, to full) → Poitiers (ENI) → Assevillers (TotalEnergies). As seeded, at 6.5 L/100 km:
Leave Pamplona with about 21 L — a bit under half a tank: you arrive at Behobia (93 km) with ~15.2 L and add ~34.8 L to reach 50 (at 6.5 L/100 km). Do not fill in Pamplona as well — the tank is 50 L, so the second stop would be a 6 L top-up.
Poitiers (458 km later): 50 − 29.8 = 20.2 L left (~311 km) — the lowest reserve after Behobia. Assevillers (452 km later): 50 − 29.4 = 20.6 L (~317 km). Rotterdam (314 km later): 50 − 20.4 = 29.6 L (~455 km). Total burned 85.6 L for 1 317 km.
At Waze pace (120–130 km/h) expect nearer 7.0 L/100 km than 6.5. Same stops at 7.0: Behobia arrival ~14.5 L (add ~35.5 L); Poitiers 50 − 32.1 = 17.9 L left (~256 km), the low point; Assevillers 50 − 31.6 = 18.4 L (~262 km); Rotterdam 50 − 22.0 = 28.0 L (~400 km). Total burned 92.2 L for 1 317 km. The plan holds at either figure.
Spain: Repsol Comete Sarea 1, 95 E5 €1.809/L, MITECO feed 03/11/2026. The two French fills are unpriced — no sourced figure; read the pump. Live legs below recompute from your stops.
Google Maps takes at most 9 waypoints between start and finish — the link keeps the first and last stops and every fuel stop, and names anything it had to leave out.
