Half Marathon races near Venta de Baños

The Valladolid Half Marathon is a road race held in late September in Valladolid, the capital of Spain's Castilla y León region. Participants run the standard 21.0975 km distance on a city course. The race is organized by Club Deportivo Atletas Populares de Valladolid and approved by the Castilla y León athletics federation. This event is approaching its 37th edition and anticipates over 2,000 participants, positioning it as a significant regional half marathon. The course is a single-loop urban circuit through the city center, beginning on Calle Miguel Íscar and concluding on Paseo Acera de Recoletos, a major avenue in Valladolid. The route passes by city landmarks, with aid stations and kilometer markers displayed on panels. Seven pacers are available to assist runners aiming for finish times of 1:25, 1:30, 1:35, 1:40, 1:45, 1:50, and 2:00. The time limit for completion is 2 hours and 30 minutes. Trophies are awarded to the top three male and female finishers in each category, and all registered runners receive a race bag containing a commemorative technical T-shirt.

Astu Trail is a mountain running event held in Astudillo, a small town in Palencia, Spain. It is scheduled for late October, with registration opening in early September and closing shortly before race day. The event provides two trail distances: 21 km for those seeking a longer mountain race, and 11 km for a shorter run. The exact route is not specified, but the format is distinctly local trail running, not a road race. The 11 km option is non-competitive, suitable for walkers, newer trail runners, or anyone wishing to participate without aiming for a specific rank. The Ayuntamiento de Astudillo organizes the event, linking it closely to the town rather than operating as part of a large commercial series.

The Media Maratón de Palencia is a 21 km race held in Báscones de Ojeda, a village in Palencia linked to the Río Boedo running event. It takes place on a Sunday near the third weekend of August, coinciding with local Virgen del Boedo festivities. The event appeals to a broad range of participants rather than elites, and the village is notable for hosting both a marathon and a half marathon despite its small population. The course begins and ends in Báscones de Ojeda, tracing the Río Boedo area over a mostly flat path. Participants will encounter asphalt and dirt sections, passing cereal fields, irrigated crops, poplar groves, quiet roads, and extended straightaways. The race challenges participants' heat management and mental endurance more than their climbing ability, situated at approximately 1,000 meters elevation, where the August sun can intensify the open course's difficulty. The limited field size means runners might experience extended periods of solitude, contributing to the event's unique character.
