Tordesillas Half Marathon 2027

Tordesillas is best known for 1494, when Spain and Portugal signed the treaty dividing the Atlantic world. Its half marathon has been running for nearly three decades, and on Sunday 11 October 2026 it reaches its 29th edition, one year short of the thirtieth.

A faster course since 2025

In 2025 the organisers redesigned the route to make it quicker. The new course was certified by the Spanish athletics federation (RFEA) and is entirely asphalt. It uses town streets and the roads just outside town, over two laps of different lengths, and starts and finishes in the Plaza Mayor. The first year went well: the 2025 edition doubled as the Castilla y León championship, and Abderrahmane Aferdi won the men’s race in 1:04:23, the second-fastest time in the race’s history. Three men finished within 20 seconds of each other. The organisers now call it the fastest half marathon in the region in 2025.

The laps are a bonus if you have friends or family watching: they can stay near the Plaza Mayor and see you more than once.

A late start

The gun goes at 11:00, which is late for a Spanish road race. Tordesillas is about 30 km from Valladolid, so you can drive over the same morning without an early alarm. On the other hand, you’ll be running in the warmest part of the morning. Drinks are at km 5, 10 and 15, and there’s food and drink at the finish. In 2025 the time limit was 2 hours 30 minutes. Check the 2026 regulations before you enter if you expect to be near it.

Entry and what’s included

• €18, through Runvasport, until Wednesday 7 October at 23:59.
• The first 500 half-marathon entrants get a commemorative technical shirt, and every finisher gets a medal.
• A 10K starts from the same square, a good option for a companion who doesn’t want to run 21 km.
• Bag drop and toilets are at the Plaza Mayor, showers are at the municipal swimming pool, and there are masseurs at the finish.

After the race

The finish is in the old town. The Royal Monastery of Santa Clara, a Mudéjar palace-convent, and the Casas del Tratado museum about the 1494 treaty are both a few minutes’ walk away. It’s a good reason to stay for lunch instead of driving straight home.
