TMBiker, operated by Sendas SAS, is a mountain-sports event brand centered on the Trasmontaña Rally de MTB and related outdoor competitions. Its program includes the 32nd edition of the mountain bike rally and the inaugural TM Trail Running event, bringing participants together for races on mountain trails. For the 2026 edition, the organizers describe a revised MTB course, with changes to sections of the route and a shared start and finish venue at La Sala.

The website serves as a practical hub for competitors and supporters, offering event news, race categories, course details, registration and entrant information, start lists, classifications, and accreditation guidance. It also provides technical guides and downloadable medical certificates, parental authorization forms, and liability waivers for both MTB and trail running participants. Beyond race information, TMBiker features event photography, videos, press and sponsorship resources, tourism information, and a store with race-related items, including a fan-zone kit.

The brand presents its events as an opportunity to enjoy the outdoors and share a passionate community experience
