Zarkus

Zarkus builds your marathon, half marathon, or 10K training plan around your goal race — not a generic template. Every plan is generated by AI trained on sport science principles: periodisation, lactate threshold, training load, and recovery. Your plan adapts week by week based on your actual training data. WHAT YOU GET • A full training plan from today to race day • Daily workouts with pace, distance, and structure (warm up, intervals, cool down) • Training load tracking so you never overtrain • Garmin sync — your activities are automatically matched to planned workouts • Compliance scoring — see how well you executed each session • Analytics: load adherence, performance trajectory, best efforts • Race day preparation: pacing strategy and km-by-km race plan BUILT ON SPORT SCIENCE Zarkus uses the same principles as Olympic-level coaches: progressive overload, periodised phases (base building, build, peak, taper), and recovery cycles. No guesswork — just structured training that works. ONE PLAN. ONE PAYMENT. Pay once per race. No subscriptions, no monthly fees. Train for your race, then decide if you want another plan. WHO IT'S FOR Intermediate runners targeting a personal best. You've run before, you train consistently, and you want a plan that takes your race seriously.
