Radikal Swim

What Radikal Swim does

Radikal Swim is a non-profit open water swimming club founded in 2012 in Barcelona, operating as Club de Natació Radikal Swim and registered with the Registre d'Entitats Esportives de Catalunya. The company is built around three membership tiers (Radikal 365 at €26/month, Radikal Friend at €60/year, Radikal Daily at €15/session) that grant access to the Barcelona International Sailing Center (BISC) facilities and open water swimming sessions. It generates revenue through a combination of recurring memberships, structured training programs (Tecnificación Radikal Swim and Total Radikal Training, priced €42–€170/month across intensity tiers), annual flagship events (La Radikal in Llafranc, Radikal ocean52 on Costa Brava, OncoSwim charity crossing, and CNB Swim in Barcelona), a calendar of weekend Radikal Xperiences across Catalonia, a Be Strength and conditioning program, and a branded e-commerce shop selling safety buoys, wetsuits and merchandise.

The technical backbone of the business is the proprietary "Radikal Swim Method" — a three-phase curriculum (BE WATER, START RADIKAL, BE RADIKAL) developed by Olympic swimmers Dani Serra (Seoul '88) and Sergi Roure (Barcelona '92) and elite coach Gerard Alemany — combined with manual underwater video analysis, the Angel Swimmers in-water safety support protocol, and FCN race license processing. Distribution is direct-to-consumer via the team.radikalswim.com member platform and the radikalswim.com website, with event ticketing processed through xipgroc.cat and OncoSwim donations managed via the Fundació Oncolliga Girona platform.

Go-to-market is community-led and event-driven: customer acquisition flows through weekly Saturday Workouts, large-scale annual events (capped between 300 and 1,600 participants), social media (Instagram, Facebook, Twitter), and partner channels (Sailfish, ocean52, Quadis Autolica, Club Natació Barcelona, Federació Catalana de Natació). Radikal Swim serves four primary customer segments — recreational open water enthusiasts, competitive and elite swimmers, solidarity/mission-driven participants, and fitness facility users — all concentrated in Catalonia with growing reach across Costa Brava, Costa Daurada and selected cross-border swim venues. The club has 14+ years of operating history, 6–7 core team members, no disclosed external funding, and no identified parent company.

Direct peers

• SwimTrek: UK-based open water swimming holiday and training company offering guided swimming holidays, technique courses, and event-style experiences globally. Most direct international comparable to Radikal Swim's open water training + community + event model.
• Global Swim Series: International network of open water swimming events across multiple continents. Closely comparable to Radikal Swim's event-organizing business (Radikal ocean52, La Radikal, OncoSwim) with similar mass-participation OWS race format.
• Club Natació Catalunya: Historic Barcelona-based swimming and water polo club with elite competitive programs. Direct competitor in the Catalonia swimming club market and the former club of Radikal Swim team member Alex Amorós. Comparable membership/facility/coaching model.

Regional players

• British Long Distance Swimming Association (BLDSA): UK governing body for marathon and long-distance open water swimming, sanctioning events and certifying swimmers. Comparable to the Federació Catalana de Natació role but for the UK — relevant as a peer in the OWS event-sanctioning and certification layer.

Others

• Sailfish: Wetsuit and open water swimming gear brand; existing partner of Radikal Swim running wetsuit testing events and member discounts. Adjacent enabling/ecosystem peer rather than direct competitor — included as a sponsor comparable.

Broad incumbents

• WOWSA (World Open Water Swimming Association): Industry body, certification authority, and media platform for open water swimming worldwide. Comparable as the broader ecosystem player that legitimizes and catalogs the OWS event/training market Radikal Swim operates in.
• Arena (Water Instinct): Global swimwear and equipment brand with deep investment in open water swimming products, sponsorships, and event series. Comparable as an incumbent OWS ecosystem player that partners with clubs/events similar to Radikal Swim, though much broader in scope.

Emerging players

• Total Immersion: Swimming technique coaching methodology company focused on efficient freestyle through structured drills and instructor certification. Comparable to Radikal Swim's methodology-led technical training approach, though more swimming-form focused than event-driven.
• Swim Smooth: Open water and pool swimming coaching methodology company offering certified instructor training and structured curriculum (the 'Swim Smooth' method). Comparable to Radikal Swim's Radikal Method three-phase coaching curriculum as a methodology-driven coaching business.
• MySwimPro: Digital swim training platform offering personalized workout plans, video analysis, and coaching subscriptions. Adjacent comparable to Radikal Swim's Total Radikal Training online planning tier — represents the digital-native competitive threat.
