What swimbike.run does

Swimbike.run is a privately held, US-based, solo-founder digital platform that provides beginner and age-group triathletes with free, AI-generated periodized training plans, a global race finder, an optional conversational AI coach branded 'Split,' and an extensive library of educational guides. The company was founded by James Simpson, a USA Triathlon Certified Coach with 20+ years of multisport racing experience and a Human Movement Science background, and operates with one stated employee. Its primary target segments are first-time triathletes, masters athletes aged 40+, and recreational age-group competitors seeking affordable, science-backed guidance without hiring a personal coach.

The core product is a race-aware periodized training plan generator that ingests a user-selected race, the athlete's experience level, available training hours, and age, then returns a week-by-week plan structured backwards from the race date. Underlying AI is delivered through Google Gemini and Perplexity, configured with domain rules including polarized 80/20 intensity distribution, MAF heart-rate cap calculation (180 minus age with modifiers), RPE-based effort control, and citation grounding from peer-reviewed sports science journals. The optional 'Split' AI coach integrates with Intervals.icu via OAuth and webhooks to compare planned sessions against completed workouts, providing adherence-aware guidance. All standard triathlon distances from Super Sprint through Full IRONMAN are supported, and plans can be generated without creating an account.

The business model is presently non-monetized. All plans are offered at zero cost, with no subscription tiers, paywalls, or premium features, and the FAQ explicitly confirms the plans are 'really free.' No funding rounds, investors, or revenue figures appear in source material, consistent with a bootstrapped or founder-funded operation. Distribution is entirely self-serve through the swimbike.run website, with no mobile app, no paid acquisition, and no B2B channel; growth depends on organic SEO, the guides library, and word of mouth.

Broad incumbents

• TrainingPeaks: TrainingPeaks is the dominant endurance-athlete training platform, offering structured workout planning, coaching tools, and training analytics for triathletes, cyclists, and runners. It is the established incumbent that Swimbike.run positions against with its free, AI-generated alternative.
• Wahoo SYSTM: Wahoo's SYSTM app delivers structured cycling, running, and triathlon training videos and workouts integrated with Wahoo hardware. It competes with Swimbike.run for triathletes seeking science-backed structured training plans, though at a paid subscription and with stronger multimedia content.
• Strava: Strava is the dominant social fitness-tracking platform for runners, cyclists, and triathletes, with a growing library of structured workouts and training plans. It is a broad incumbent that captures engagement and training data Swimbike.run's AI coach also depends on.

Direct peers

• Final Surge: Final Surge is a training platform for endurance athletes and coaches that includes workout calendars, plan builders, and athlete-tracking features. It competes with Swimbike.run for triathletes seeking structured plan delivery and coach-athlete workflows.
• AI Endurance: AI Endurance is an AI-powered endurance coaching platform that generates personalized training plans for triathletes, cyclists, and runners. It is the closest direct competitor to Swimbike.run, targeting the same niche with similar LLM-driven plan generation.
• FasCat Coaching: FasCat Coaching provides personalized triathlon and cycling coaching programs with structured periodization and trainer-led guidance. It targets the same age-group and beginner triathlete segments as Swimbike.run but with paid human-coach services.

Emerging players

It is a methodology-aligned peer in the endurance coaching space.
• Humango: Humango is an AI-powered adaptive training platform for endurance athletes that adjusts plans based on completed workouts. It overlaps with Swimbike.run's adherence-aware coaching vision through its Intervals.icu-style feedback loop, though it is more focused on running and cycling than triathlon.
