You know it was the asteroid. You ride anyway. TRAILASAUR is built for the kind of person who tracks descents, debates K–Pg boundary evidence, and thinks both matter.

TRAILASAUR logs your activity, rewards your effort, and builds a record of your outdoor life that actually means something. • Real-time GPS tracking for rides, hikes, skiing, and walks • Expeditions: multi-stage quests tied to real-world activity • Earn TrailBites and unlock Relics in the Artifact Vault • Spend TrailBites in the Tavern Shop on real gear and accessories • Bike setup logging for fork, shock, tires, drivetrain, and pressure • Smart PSI calculators for tires and suspension • Strava sync with improved export reliability • Post-activity summaries with stats, maps, and badges • Trekker DNA: your rider profile, refined over every session • Themes, profile customization, arcade games, and weekly nudges From the bike park to the summit to the skin track, every adventure counts toward your legacy.
