With the triathlon calculator, you can easily determine your individual target times and pacing for all triathlon distances. Whether you are racing a sprint, Olympic, middle or long distance triathlon, simply enter your planned speeds or pace values and instantly receive accurate split times for swimming, cycling and running, as well as your total race time.

The triathlon calculator combines your inputs for speed, pace or time with standard race distances. You can also include transition times to get a more realistic estimate of your final race result. The results help you plan your race strategy and optimize your training preparation.

Important notes on transitions and planning

Transition times (T1 and T2) are an essential part of the race and should not be underestimated.
T1 is the transition from swimming to cycling and usually takes longer than T2.
T2 is the transition from cycling to running.

All entered speeds should be realistic and appropriate for your level of experience. When planning your race, also consider external factors such as weather conditions, course profile and race-specific rules.

Race tips

Swimming
The swim segment usually takes place in open water or in a pool. Mass starts, navigation and wetsuit use can all affect your pace.

Cycling
Drafting is not allowed in most triathlon races. Exceptions include the Bundesliga and certain sprint events.

Running
Plan your running pace conservatively, as running performance after cycling is typically lower than in a standalone running race.

Transition zones
Practice transitions during training and prepare your equipment carefully. Efficient transitions can save valuable time.

The triathlon calculator helps you set a realistic target time and optimally plan each discipline and transition. Please keep in mind that actual race time depends on many factors and that the calculator should be used as a planning tool and guideline rather than a guaranteed prediction.
