Splitpace does arithmetic on the numbers you give it, and — where your training partner is switched on — asks a language model to suggest a training plan. This page says plainly what neither of those things can tell you, and where the rest of the numbers come from.
Training and your health
Splitpace is not a medical service and gives no medical advice. It does not know your medical history, it does not monitor you between sessions, and it cannot tell whether a session is safe for you today. Talk to a doctor before starting or significantly changing how you train, and especially if you are managing an existing condition, returning from injury, pregnant, or new to endurance sport.
Stop exercising and get urgent medical help if you experience chest pressure or pain, fainting or near-fainting, severe breathlessness, or anything else that alarms you. No plan on this site is worth an emergency.
Endurance training carries real risk of injury and illness. You train at your own risk, and the decision to start, continue or stop a session is always yours.
A pacing plan is arithmetic, not an assessment of your fitness. The planner takes the splits, distances and target you enter and works out what follows from them. A required pace is the pace your goal implies — not a prediction of your finish time, and not a probability of success. The reference gauge beside your goal compares it to a rounded typical finish for that course; it uses none of your training and makes no claim about you. Once you record a field test, a race’s page also shows where each race pace sits among the Easy, Medium and Hard bands that test sets, beside the paces you have logged: a description of your own numbers, not a judgement of whether you can hold the pace.
What the AI training partner is and is not
Where your AI training partner is available to you, the plan and the conversation are generated by a third-party AI model. Model output can be confidently wrong, and it can be wrong in ways that look reasonable. Read it as a suggestion from something that has never met you.
It is an AI training partner — not a person, not a qualified human coach and not a clinician. It cannot diagnose anything, cannot clear you to train, cannot prescribe treatment, and cannot promise a finish time or an injury-free season. Where it touches on pain, illness or injury, it is built to tell you to see someone qualified — and that is the right answer, not a deflection.
When you tell it about chest pain, fainting, severe breathlessness or signs of a stroke, it answers with emergency guidance and changes nothing. When you tell it about pain, injury or illness, it will only take training out or shorten it, and a new plan waits, until you tell it the problem has been checked.
Nothing reaches your calendar without you. A generated plan and any proposed change are shown to you first and applied only when you accept them. You can change or remove any of it afterwards. A proposed change is limited to the next two weeks and can never alter a workout you have already completed.
Your training partner reads what you tell it, your training plan, your race goal and pacing plan, your field tests and the training you have logged yourself. When you talk to it about your calendar, it can also read what your watch recorded, through Apple Health or Strava, with heart rate, pace and power, and the other things listed on the card you agree to. It reads a heart rate as a record of a session, never as a diagnosis or a sign that you are ready for more. It does not read your sleep, your routes, or anything that card does not list. Once you have agreed to your training partner, it also reads your training once a night, after something new, and leaves a note on Today; that changes nothing until you accept it. Exactly what is sent, and to whom, is in the Privacy Policy.
Where the numbers and events come from
Course distances for the sprint, Olympic, half and full presets are the standard published distances. Real events vary, so check your event’s own published course and use custom distances where it differs.
Starting paces in the planner’s templates are built-in examples to edit, not values derived from your training history.
Reference finish times behind the goal gauge are rounded population reference points drawn from published analyses of race results. They are rounded starting points, not pooled statistical means, and not forecasts for your event.
Event listings come from World Triathlon, RunSignup and IRONMAN catalogues. Splitpace does not operate these events and saving a race here does not register you for it. Always confirm dates, distances and entry with the organizer.
Illustrative examples — the sample activities and the long-term outlook shown on the home page — are made up to demonstrate the product. They are not anyone’s real data, not personalized to you, and not a validated forecast or a promise of improvement.
