Register today to ensure you are part of this iconic swim marathon.

So far, almost seventy swimmers have registered for an adventure of more than 30 kilometres along the Ebro River between Tivenys and Amposta.

This year’s start list already includes a strong international field from across Europe and beyond, with swimmers confirmed from Spain, the UK, Netherlands, Italy, France, Ireland, Canada, Colombia, Malaysia and more, making it one of the most diverse UltraEbre line-ups to date.

A unique river marathon swim experience

UltraEbre is widely recognised as more than a single-day race. The event is designed as a multi-day experience that allows swimmers and support teams to acclimatise, train in the river, attend briefings and lectures, and enjoy the landscapes and culture of the Terres de l’Ebre region together.

Participants benefit from:

• Supervised swimming under World Aquatics open-water rules
• Organised safety, medical and physiotherapy support
• Official transport logistics for swimmers and kayakers
• Access to training sessions and local pools in the days before the event
• Structured pre-race briefings and community activities

Combined with the clean, warm summer water (around 24 °C) and the natural assistance of a downstream course, UltraEbre offers an ideal environment for swimmers preparing for major marathon challenges.
