Valencia Marathon: Chasing Personal Bests on Spain's Fastest Course
It's 8 AM on a December morning in Valencia, and the air hums with a particular energy. Runners from 80 countries stretch along wide avenues near the futuristic City of Arts and Sciences, their breath visible in the crisp Mediterranean air. The temperature hovers around 15°C (59°F). Perfect. No wind. No rain. Just fast, flat tarmac stretching ahead like an invitation.
Valencia has earned its reputation quietly but convincingly. The Trinidad Alfonso EDP is the 4th fastest marathon in the world, and the numbers tell the story. Since 2017, its streets have seen nine world records broken. The course records speak volumes: Ethiopian runner Sisay Lemma completed the course in 2 hours, 1 minute, and 48 seconds, and his compatriot Amane Beriso finished in 2 hours, 14 minutes, and 58 seconds. These aren't flukes. This is a course engineered for speed.
Why Valencia Delivers Fast Times
The secret lies in a perfect trifecta: course design, weather, and timing. The track is smooth, with very little (if any) elevation gain. It is at sea level and even passes by the seaside. The course winds through Valencia's historic center and across broad avenues, offering long, uninterrupted stretches where runners can settle into rhythm without disruption.
Then there's December. While most of Europe shivers, Valencia offers what serious runners dream about. The weather in Valencia in December is moderately chilly and breezy, with average highs of 60°F (16°C) and lows of 46°F (8°C). The December weather reliably cool, and the pace groups deep enough to carry dozens of runners to career days. The Mediterranean city delivers consistent conditions year after year.
December in Valencia means sunshine too. Valencia sees on average 7 hours of sunshine per day in December, giving runners clear skies without the brutal heat that plagues summer marathons. The sea breeze from the nearby coast provides natural cooling without creating challenging wind conditions.
A Course Built for Records
Start at Plaça de la Marató. Finish on the water walkway at the City of Arts and Sciences. Between these points lies 42.195 kilometers of opportunity. It runs through wide avenues and the historic center of the city, but the real story is what the course doesn't have: hills, tight turns, or technical sections that break momentum.
Valencia has earned its reputation as the sport's go-to venue for personal bests and record attempts. The course is famously flat and fast. Elite pacemakers guide large groups through perfectly calibrated splits, creating what amounts to a 26.2-mile time trial. The pace groups run deep. The support runs strong. And the results speak for themselves.
In 2023, a record 13 athletes ran under 2:06 in the men's race alone. That's not just elite performance. That's a course doing exactly what it was designed to do: remove obstacles between runners and their goals.
The 2025 Edition: Record-Breaking Potential
The 2025 Valencia Marathon, scheduled for December 7, is already shaping up as one of the fastest races in history and one of the most competitive. The elite field reads like a who's who of distance running. Sisay Lemma, who set the Valencia course record in 2023 with his 2:01:48 win, still the fourth-fastest marathon in history, headlines the men's race.
The women's field matches that intensity. Peres Jepchirchir, the reigning Olympic champion, and Joyciline Jepkosgei, a former London and New York City Marathon winner with a 2:16:24 best. That top trio alone accounts for three of the ten fastest women in history. When the fastest runners in the world choose Valencia, they're making a statement about what this course can deliver.
If conditions mirror Valencia's typical early-December range, mid-50s Fahrenheit with light winds and low humidity, multiple athletes could dip under 2:18 and the course record might once again be under threat.
More Than Elite Excellence
Valencia welcomes all runners, from international elites to first-time marathoners. The same flat course that enables world records also creates ideal conditions for personal bests at every level. The World Athletics Platinum Label race designation confirms its elite status, but the race experience itself proves accessible.
Recognized as Spain's top marathon, it offers an electrifying atmosphere with over 200,000 spectators, lining the course from start to finish. Hot chocolate and churros at aid stations add Spanish flavor to standard race support. The finish line sits dramatically atop water at the City of Arts and Sciences, providing an architectural exclamation point to 26.2 miles of effort.
The city itself enhances the marathon weekend experience. Valencia blends coastal Mediterranean charm with striking modern architecture. The historic Barrio del Carmen district offers winding medieval streets. The City of Arts and Sciences provides futuristic visual drama. The Barrio del Carmen, home to the impressive Gothic Valencia Cathedral. The City of Arts and Sciences, a stunning architectural marvel by Santiago Calatrava, featuring a science museum, an opera house, and Europe's largest aquarium.
Practical Details for Race Week
Race logistics match the course's efficiency. The ExpoDeporte Valencia opens Thursday through Saturday before the Sunday race, housed at Feria Valencia's Pavilion 5. No race-day bib pickup exists, encouraging runners to arrive with time to spare and stress to spare.
December weather demands smart packing. Daytime temperatures feel pleasant for walking and outdoor dining, but Valencia's evenings can get quite chilly in December. While during the day, you might get by with a sweater and light jacket, you'll definitely need a coat when the sun goes down. Race morning temperatures typically sit perfect for running: cool enough to prevent overheating, warm enough to avoid numbing fingers.
Accommodation near the start and finish area makes race morning simpler. Valencia's efficient public transport and walkable streets mean staying anywhere in the city center works well. Book early. The race draws over 30,000 participants, and hotels fill quickly as the date approaches.
The Benchmark Race
For the world's best, and for the Americans chasing breakthrough times, Valencia has become more than just a race. It's a benchmark. When runners consider where to chase a personal best or qualify for major championships, Valencia consistently appears on the shortlist.
The combination of course design, December weather, and proven results creates something rare: a marathon where external factors genuinely help rather than hinder performance. The 42cal Race Directory lists hundreds of marathons worldwide, but few offer Valencia's particular blend of speed-enabling conditions and world-class organization.
Once a regional race known mainly to Spanish amateurs, the Valencia Marathon has transformed into one of the world's premier stages for fast times. Its mix of elite pacing, cool weather, and a perfectly engineered course has turned it into the December destination for record chasers.
The December 7, 2025 edition promises another chapter in Valencia's evolution as a speed factory. The elite fields. The perfect conditions. The proven course. Everything aligns for fast times and personal victories.
Valencia delivers what serious marathoners seek: a fair test on a fast course with ideal conditions. The records keep falling. The personal bests keep coming. And runners keep returning to Spain's Mediterranean coast each December, chasing the times they know this course can deliver.
Some marathons test you with hills, weather, or challenging terrain. Valencia does something different. It removes obstacles. It creates optimal conditions. It lets you run your fastest possible race. For runners chasing personal bests, that's exactly what matters.
