Its reputation for producing personal bests is well earned and is the reason the field is now overwhelmingly international.
- Terrain
- Flat
- Distances
- Marathon
- Weather on race day
- Early December on the Spanish Mediterranean coast is close to perfect for racing: starts in the 40s or 50s, highs in the 60s, usually dry and still. The weather is a large part of the course's reputation.
What to train for
Pure marathon-pace fitness, and a build that runs through the northern autumn.
A December date means your peak weeks fall in October and November, so plan for shorter daylight and colder long runs than the race itself will deliver.

Your build to race day
Taper
Tapering for the Valencia Marathon
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is flat, so pacing decides the day: rehearse your goal pace in short segments during race week. With the race on December 6, 2026, your taper starts around November 18, 2026.
