A very limited number of bib numbers
At the time of publishing this information, Triathlon News has eight promotional bib numbers available: four for Sprint, two for Olympic and two for Middle Distance.

The promotion is valid exclusively for new registrations and will remain available while there are race numbers in the store.

How does registration work?
Purchasing a race number at the Triathlon News store does not automatically complete the official registration for the event.
Once the order is confirmed, Triathlon News will send the request to the organizer, copying the buyer. The organizer will verify the purchase, generate the corresponding code, and send it directly to the participant via email.
With that code, the athlete must then access the official event platform, complete their information and finalize the registration.
The process is manual, so the code is not generated immediately upon completion of the purchase.
The Guadalix Duathlon takes place on September 6th
The 2026 Guadalix de la Sierra Duathlon will feature Sprint, Olympic, and Middle Distance races. The Middle Distance race will also serve as the Madrid Middle Distance Duathlon Championship.
The organization has confirmed that the event will take place and has also announced a 20-minute extension to the cut-off time after the cycling portion of the Medium Distance race.
