Geschwindigkeit, Distanz & Zeit-Rechner

The Speed-Distance-Time Relationship Explained

The speed-distance-time triangle is one of the most fundamental relationships in physics and endurance sport. The three core equations are speed equals distance divided by time, distance equals speed multiplied by time, and time equals distance divided by speed. Enter any two variables in this calculator and the third is returned automatically. For running and cycling, the calculator also converts between speed units like kilometres per hour, miles per hour, and metres per second, and between pace units like minutes per kilometre and minutes per mile. These conversions matter because training plans and race information come in many formats depending on country and discipline. Cyclists typically express effort in kilometres per hour while runners prefer pace in minutes per kilometre, even though both describe the same physical reality. Mastering the triangle lets you flex between units without losing track of your actual intensity.

How to Apply the Triangle to Workouts and Races

The equations become practical tools the moment you apply them to real training scenarios. Planning a 90 minute long run at 6 minutes per kilometre? Multiply 90 minutes by the speed of 10 kilometres per hour to get 15 kilometres of total distance. Prepping for a 180 kilometre century ride averaging 30 kilometres per hour? Distance divided by speed gives 6 hours of saddle time, which dictates nutrition needs of roughly 60 to 90 grams of carbohydrates per hour. Chasing a Boston qualifier of 3 hours for the marathon? 42.195 kilometres divided by 3 hours equals 14.065 kilometres per hour, or 4 minutes 16 seconds per kilometre pace. Using the calculator to reverse-engineer goal paces from target times and vice versa is one of the highest leverage habits in endurance sport preparation because it translates abstract goals into concrete training sessions.
