Alcázar de San Juan Half Marathon 2027

The Alcázar de San Juan Half Marathon is run as the Memorial Mariano Rivas Rojano. Its 28th edition starts at 9:30 on Sunday 18 October 2026 from the Pabellón Vicente Paniagua at the town fairground. The course is a single flat lap of 21.097 km. That suits La Mancha, where the land barely rises between here and the windmills of Campo de Criptana next door.

A weekend for everyone

Club Maratón Altomira has built a full programme around the half:

When	Race
Saturday 17 October, 17:00	1st children’s mini race
Sunday, 9:30	Half marathon and 2nd 10K
Sunday, 9:45	Charity 6K for the multiple sclerosis association (€6, all proceeds donated)
Sunday	23rd adapted race for people with disabilities (free entry)

If a friend or family member doesn’t run 21 km, there’s something for them too.

Time limits

You have 2 h 30 min for the half and 1 h 30 min for the 10K. On a flat single loop there’s no hill to walk. The most likely problem is the plain’s open exposure: if it’s windy, stay in a group on the stretches with the wind in your face.

Entry

• €12 from 1 to 31 August, then €16 from 1 September to 11 October.
• Entry is online only through Crono3, so there’s no registration on the day.
• Trophies go to the top three men and women overall and in each age group.

Getting there

Alcázar de San Juan is one of Spain’s historic railway junctions, with direct trains from Madrid and the south, so you can arrive the night before without a car.
