What UltraSwim 33.3 does
UltraSwim 33.3 is a Swiss-based events operator that runs a branded series of multi-day open water swimming races under the Epic Adventure Swim Race banner. Founded in 2022 and operated through Inspire Through Sport Sàrl (Lutry, Vaud), the company organizes events in which the English Channel-equivalent distance of 33.3 km is split over four days and five to seven swims, with a marathon day of roughly 10 km on day three. It serves experienced open water swimmers aged 14 to 75 (median age 50, 52% female) seeking a structured, supported endurance challenge in warm-water destinations including Croatia, Montenegro, Greece, Switzerland, Spain (Costa Brava), and — from December 2026 — the Caribbean (Nevis). Adaptive athletes, solo channel aspirants, and age-group competitive swimmers are explicit secondary segments.
The core product portfolio centers on three distance formats (33.3 CLASSIC, 33.3/2 BUILD half-distance, 16.65 COMPACT 2-day weekend) plus a ULTIMATE non-stop 33.3 km add-on. Service packaging is tiered from ULTRA (essential, shared 3–4 star hotel) through ULTRA+ and ULTRA+ [5*] (premium 4–5 star hotels, dedicated transfers, video analysis, sports massage) to ULTRA++ (luxury concierge at €7,500). Pre-event preparation camps, F3 non-swimmer partner packages, and a 33.3 multi-event Passport discount round out the offering. The technology stack is operational rather than proprietary: Monday.com booking forms, Stripe payments, Xero accounting, Squarespace website, and third-party GeoRacing GPS tracking; the multi-day format itself is the principal proprietary asset.
Revenue is generated primarily through per-event entry fees (€750 to €7,500+), with secondary income from package upgrades, add-ons, merchandise, and coach/club affiliate commissions. Distribution is direct-to-consumer via the website and email, supplemented by a coach affiliate channel and ambassador-led organic social. Marketing relies heavily on community referral (44% of swimmers come through recommendations), the Strava club (1,000+ members), an 80-page FLOW magazine, and three consecutive RaceCheck Gold Awards (2023–2025) as brand proof. The company is founder-led by Mark Turner, has 8 core employees, and has not raised external capital.
