Territorio Sierra Norte Bike Challenge

The Territorio Sierra Norte Bike Challenge is a multi-format mountain-bike and gravel event in the Sierra Norte de Madrid, based around the Lozoya Valley. The last edition confirmed by the organiser took place on Saturday 27 September 2025, and the 2024 edition was held in Rascafría. The date of the next edition has not been announced yet.

Routes and distances

The organiser’s website lists the following formats, with figures from its route summaries:

• Non Stop: an ultra-marathon of 210 km with 4,607 m of accumulated elevation, presented by the organiser as the Madrid regional ultra-marathon championship.
• Gravel: 101 km with 1,600 m of accumulated elevation, roughly 80% on dirt tracks and 20% on regional roads.
• Family: a 20 km promotional ride through the Lozoya Valley.

Registration

Entries for the 2025 edition were handled through the event’s official website, which also links a one-day licence form for riders without a federation licence. Prices and opening dates for the next edition have not been published. Check the official website for updates.

Why race it

The event combines a demanding 210 km non-stop challenge with a gravel option and a family ride, so riders of very different levels can take part in the same weekend. All formats use the tracks and landscapes of the Lozoya Valley and the Sierra Norte de Madrid. The next edition’s date has not been announced yet.

Where to stay

With the Non Stop and Marathon formats demanding an early start, it pays to arrive in the Lozoya Valley the day before: you can collect your bib without rushing, check your bike over and get a proper night’s sleep before a long day in the saddle. Staying in the valley also means a short transfer to the start in Rascafría and a place to recover once you finish.
