Date: June 13–21, 2026
Location: Caminha, Portugal
Distance: ~1,000 km in one continuous stage
Event Type: Self-Supported Ultra Bikepacking Challenge
GRANDIAGONAL is a one-country, end-to-end bikepacking challenge across Portugal that pushes both body and spirit. Over seven days and five hours, participants ride approximately 1,000 km in a single, continuous stage, traveling from one coast of Portugal to the other. With only minimal external structure, this event is designed for riders who thrive on self-sufficiency, endurance, and the raw beauty of the open road.
As a self-supported race, GRANDIAGONAL emphasizes autonomy. Riders follow the route using GPS navigation, manage their own food and rest schedules, and carry the gear they need. There’s no support crew—only the organizer’s minimal checkpoints and a shared experience of challenge and discovery.
The route traverses Portugal’s diverse terrain: oceanic coastlines, rolling hills, river valleys, and remote rural landscapes. Riders will experience vastly changing light, weather, and scenery—one moment beside sandy shores, the next high above verdant inland terrain. The continuous format means there are no stages or breaks; the clock never stops until the finish.
GRANDIAGONAL calls to seasoned bikepackers seeking ultra-distance adventures. It demands high levels of planning, physical fitness, mental toughness, and a willingness to embrace discomfort and uncertainty. But the payoff is a journey across an entire country in which every kilometer matters—and every sunrise, vista, and challenge becomes part of a story.
GRANDIAGONAL — coast to coast, one continuous ride, one epic narrative.
