Four Phases. One Complete System.
TriDot® redefines all four phases of training program design, intelligently assessing, prescribing, evaluating, and predicting with unmatched precision.
Assess
- Identifies your true performance baseline across swim, bike, and run
- Normalized for age, gender, temperature, humidity, and elevation
- Every athlete starts from an accurate starting point, not a guess
Prescribe
- Normalized Training Stress® (NTS™) accurately quantifies the physiological stress of each session
- EnviroNorm® technology adjusts intensities for your exact training environment
- The right training at the right time, before every session
Evaluate
- TrainX® score measures how well prescribed training was executed
- Replaces vanity metrics like total distance with real insight
- Tracks training-execution quality and consistency over time
Predict
- RaceX® predictions calculate your optimal race paces and splits
- Considers local terrain, temperature, humidity, and elevation
- Toe the line with a data-backed plan, not a hope

What is TriDot?
TriDot is an AI-powered triathlon training platform that builds personalized swim, bike, and run plans using 20+ years of real athlete data and FitLogic™ technology, so triathletes train less, race faster, and reduce overtraining risk.
Do I need a triathlon coach to use TriDot?
No, TriDot's AI-driven training works on its own for athletes at every level. For those who want additional human support, the Premium: Coached plan pairs TriDot's technology with a dedicated certified coach for frequent one-to-one communication.
How is TriDot different from a generic training plan?
Generic training plans are built for an average athlete. TriDot assesses your true performance ability, prescribes the right training at the right time, evaluates how well you executed it, and predicts your race day performance, all personalized to your own data across swim, bike, and run.
Can beginners use TriDot?
Yes. The Lifestyle plan is built for athletes planning one to two shorter-distance races per year, making it a fit for beginners, while more advanced plans support athletes racing multiple distances throughout the year.
What distances does TriDot support?
TriDot supports training across sprint, Olympic, and longer triathlon distances. Plans range from scheduling a single sprint or Olympic race to planning multiple races of any distance, or unlimited races on the Complete and Premium: Coached plans.
What does TriDot's four-phase system include?
TriDot's system has four phases: Assess (identifying your true performance ability), Prescribe (delivering the right training at the right time), Evaluate (measuring training execution and response with TrainX® score), and Predict (RaceX® race day forecasting and pacing).
Can I cancel anytime?
Yes. Every TriDot plan starts with a 14-day free trial that requires no credit card, and you can cancel anytime.
Generic Training Is Costing You Results You've Already Earned.
You already know that a hard bike day affects your run. That a bad week at work changes everything. TriDot® tracks those variables so your training always reflects reality, not just a calendar.
