Fast Winter & Early-Spring Marathons
A winter race turns holiday-season discipline into a head start on the year. These are the standout fast courses from December through March, when cool weather is all but guaranteed.

Valencia Marathon
Valencia, Spain · December · 60 m gain · -5 m net
The 'ciudad del running' earns it: dead flat, wide, sheltered streets, December air, and a field stacked with PR-hunters. The blue-carpet finish over the City of Arts lagoon is one of the sport's great closing images. If you want one fast race in Europe, this is it.
PR score 10/10 - 2
California International Marathon
Sacramento, USA · December · 202 m gain · -104 m net
Net downhill (~100 m) from Folsom to the State Capitol, but rolling the whole way — it drops in waves rather than one glide. The relentless gentle rollers reward runners who trained hills; more Boston qualifiers per capita than almost any US race.
PR score 9/10 - 3
Dubai Marathon
Dubai, United Arab Emirates · January · 25 m gain
Arguably the flattest marathon on the planet — a sea-level out-and-back along Umm Suqeim Road where a pancake profile and pre-dawn start produced a stack of 2:03–2:04 elite times. Featureless, windless on a good day, and brutally honest.
PR score 9/10 - 4
Houston Marathon
Houston, USA · January · 65 m gain
Flat, fast loop where American records and debuts happen. Well-drilled organisation, sharp corners kept to a minimum, and a January date that guarantees you trained through the holidays.
PR score 8/10 - 5
Seville Marathon
Seville, Spain · February · 35 m gain
Possibly the flattest certified marathon in Europe — 35 m of total climbing. Fewer crowds and less glamour than Valencia, but an even better elevation profile and a stadium-track finish.
PR score 9/10 - 6
Osaka Marathon
Osaka, Japan · February · 85 m gain
Japan's second-biggest marathon and a genuinely quick one: flat city streets, immaculate organisation, and cold late-winter air. A short rise around the 33 km mark is the only feature that needs respecting.
PR score 8/10 - 7
Tokyo Marathon
MajorTokyo, Japan · March · 60 m gain · -38 m net
Gently net-downhill first half through Shinjuku, then flat out-and-back sections along wide avenues. Several 180° turnarounds late require patience, but conditions and surface make this a genuine PR course.
PR score 8/10 - 8
Barcelona Marathon
Barcelona, Spain · March · 150 m gain
Sagrada Família, Camp Nou, and the seafront in one loop. Gently rolling in the first half (the city tilts toward the sea), then a fast, flat second half — a course that rewards negative-split patience.
