Horizontes Backyard Ultra

About this event

Horizontes Backyard Ultra brings the intriguing backyard format to the rolling hills of Montes da Senhora in Portugal. Runners tackle a 6.7km loop every hour, on the hour, until only one remains. The terrain winds through Portuguese countryside, offering a mental and physical chess match as much as an endurance test. It's a format that strips trail running down to its essence: how long can you keep going when the only opponent left is yourself? The event attracts experienced ultrarunners drawn to the backyard format's unique challenge, where strategy, pacing, and mental fortitude matter as much as fitness. Set in late March when Portuguese weather tends to be mild, it's a compelling entry point for those curious about this growing format.
