Madrid to London distance

Madrid to London by road

The fastest driving route is 1,731 km (1,075 mi) long and takes about 18 hr 50 min without stops or traffic. It includes the Channel crossing on Le Shuttle, the train that carries cars through the tunnel between Folkestone and Calais: 58.5 km (36.3 mi) and about 35 min in the calculation, not counting check-in. It runs mostly on the A10 (345 km), the A-1 (258 km), and the A28 (242 km).

Of the 1,731 km, 468 km are in Spain, 1,096 km are in France, and 130 km are in the United Kingdom. That’s an average of 92 km/h (57 mph). Spain’s traffic authority (DGT) recommends a break every two hours or 200 km: with 9 stops of 20 minutes, the trip takes about 21 hr 50 min. At about 8 hours behind the wheel a day, it’s a 3-day drive. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.

Straight-line distance and bearing

In a straight line, the shortest distance over the Earth’s surface, Madrid and London are 1,263 km (785 mi) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.

The road is 37% longer: for every 100 km in a straight line you drive 137. That’s a big detour: the fastest route strays quite far from the straight line. Of the 34 Spain–Europe driving pairs in this series, it ranks 9th for detour (the average is 31%).

From Madrid, London lies to the north (bearing 11°), and from London, Madrid lies to the south. The straight line reaches London on a bearing of 14°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.

Halfway between Madrid and London

Halfway along the straight line, 631 km (392 mi) from each city, is the point 45.9802° N, 2.0874° W. It falls in the water; the closest place is Ars-en-Ré (Charente-Maritime, France, pop. 1,444), 50.9 km away. The nearest town of 20,000 people or more is La Rochelle (Charente-Maritime, France, pop. 76,810), 75.1 km away.

By road, the halfway point is 865 km (538 mi) from each city, near Aiffres (Deux-Sèvres, France, pop. 4,815), 1.6 km away. The nearest town of 20,000 people or more is Niort (Deux-Sèvres, France, pop. 54,660), 6.5 km away. The two midpoints are 135 km apart: if you want to meet halfway, the one on the road is the useful one.

Time difference and flight

London is 1 hour behind Madrid all year (United Kingdom Time versus Central European Time): when it’s 12:00 in Madrid, it’s 11:00 in London.

A direct flight would take about 2 hr 5 min. That’s an estimate: 30 minutes for takeoff, climb, descent and landing, plus the 1,263 km straight line at 800 km/h (about 497 mph), a typical airliner cruising speed. Real schedules depend on wind, routing and airports, and not every pair has a direct flight.

The two cities

Madrid has 3.5 million people (INE population register, January 1, 2025) and London 9.0 million people (GeoNames).
