Pancake flat. PR-hunting ground of the majors.

NOV 1, 2026 · NEW YORK, NY
Five boroughs, five bridges. Every borough has a cost.

SEP 27, 2026 · BERLIN, DE
Twelve world records called this course home. London finally took the crown, but Berlin built the throne.

APR 26, 2026 · LONDON, UK
Sawe ran 1:59:30 here. The world held its breath. It still hasn't exhaled.

MAR 7, 2027 · TOKYO, JP
A point-to-point love letter to the city. Shinjuku to Tokyo Station, mostly flat, impeccably organized.

60m
MAR 14, 2027 · BARCELONA, ES
Sagrada Família at km 14, the Mediterranean at your shoulder, two sneaky climbs at 26 and 40. Europe's quiet PR machine.
100m
APR 11, 2027 · PARIS, FR
Cobblestones off the Champs-Élysées, two forest loops, and a wall at km 34 that's claimed more PB attempts than it should.

164m
APR 11, 2027 · ROTTERDAM, NL
Three world records, four of the all-time ten fastest. The Erasmus Bridge is the only hill — and it barely counts.
26
52m
OCT 31, 2027 · AMSTERDAM, NL
Below sea level, through the Rijksmuseum and along the Amstel. Flat is the trap — October wind on the river does the damage.
29
91m
APR 18, 2027 · MANCHESTER, UK
Old Trafford to Oxford Road. The UK's flattest major — Mancunians lining every mile make sure you never slow down.

MAY 3, 2026 · TORONTO, ON
105m of net drop, but the North York hills in the first 12k demand respect.

You get all the hills and most of the drop. Front-load effort, bank time.

MAY 10, 2026 · COPENHAGEN, DK
Nyhavn, Tivoli, Christianshavn — flat all the way through. The turns are wide and the wind off the Øresund is the only thing that fights back.
31
85m
MAY 30, 2026 · STOCKHOLM, SE
Seven districts, 14 islands, one finish inside the 1912 Olympic Stadium. Prettier than it is fast — the rolling Kungsholmen climbs remind you this is Scandinavia, not the Netherlands.
52
221m
APR 26, 2026 · HAMBURG, DE
Where Kipchoge announced himself in 2013. Along the Elbe, the Alster, and the harbour — almost flat, very fast, impossibly loud.
28
90m
OCT 11, 2026 · MUNICH, DE
Olympiapark to Marienplatz to the English Garden and back. Gently rolling, impossibly scenic, and the Werksviertel fan zone at km 30 hits like a second wind.
36
120m
MAR 14, 2027 · ROME, IT
Colosseum start, Vatican at km 17, Spanish Steps, Piazza Navona — then cobblestones remind you this is Rome, not a track.
