Calculate cycling pace, speed, time, and distance for any ride. Convert between km/h, mph, min/km, and min/mi for training planning.
Whether you're planning a century ride, tracking training progress, or preparing for a timed cycling event, knowing your pace and how it relates to speed, time, and distance is essential. Cycling pace can be expressed in several ways — kilometers per hour, miles per hour, minutes per kilometer, or minutes per mile — and converting between them quickly helps you set realistic goals.
Unlike running, cycling pace is heavily influenced by external factors: wind, gradient, road surface, and drafting can cause the same effort level to produce wildly different speeds. A rider averaging 30 km/h on a flat, calm day might only manage 22 km/h into a headwind or on rolling terrain. Understanding how these factors affect your pace helps set appropriate targets for different conditions.
This calculator lets you find any missing variable when you know two of the other three (speed, time, distance). It also generates pace charts, split tables, and equivalent paces across different units so you can plan your ride precisely and track your performance over time.
Planning rides requires knowing how long they'll take at your expected pace. This calculator converts between formats cyclists use and generates useful pace tables for event planning and training. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.

Speed = Distance / Time. Pace (min/km) = 60 / Speed (km/h). Distance = Speed × Time. Time = Distance / Speed. All conversions: 1 mile = 1.60934 km.
Result: 30.8 km/h (19.1 mph)
100 km ÷ 3.25 hours = 30.77 km/h. This corresponds to a pace of 1:57 min/km or 3:09 min/mi. At this pace, a 40 km time trial would take about 1 hour 18 minutes.
Cyclists use speed (km/h or mph) as the primary pace metric, unlike runners who think in minutes per kilometer. This makes sense because cycling speed varies enormously with conditions — a difference of just 5W of power output might mean 1-2 km/h difference at lower speeds but only 0.3 km/h at higher speeds due to the exponential relationship between speed and air resistance. When comparing performances, normalized power and speed over specific courses are more meaningful than raw pace numbers.
Effective pacing strategy is crucial for cycling events. For time trials and triathlons, even pacing (consistent power output) produces the fastest times. For road races, the dynamics of the peloton dictate pace. For gran fondos and century rides, starting conservatively and maintaining effort on climbs while recovering on descents optimizes overall time. Use your training data to set realistic pace targets — your average speed in training at threshold effort is a good predictor of event pace.
Triathletes often need to think about pace across sports. As a rough conversion: cycling at 30 km/h requires similar effort to running at about 12 km/h (5:00/km) for most athletes. The exact relationship depends on individual physiology, but cycling speed is roughly 2.5-3× running speed at the same effort intensity, making this calculator useful for cross-training planning.
For recreational cyclists, 20-25 km/h is typical. Regular club riders average 25-30 km/h. Competitive amateurs average 30-38 km/h, and professionals average 40-45 km/h in races.
Unlike running, cycling speeds vary enormously with conditions. Speed (km/h) is more intuitive for cycling because it directly relates to the bike computer display. However, min/km pace is useful for triathlon transitions and comparing across sports.
Wind resistance is proportional to the cube of speed. A 20 km/h headwind can reduce your speed by 15-25% at the same effort. That's why average speed on hilly or windy rides is always lower than on calm, flat rides.
Century rides (160 km): aim for 25-30 km/h for 5-6 hours. Gran Fondos: 28-35 km/h depending on terrain. Time trials: 35-45 km/h. Triathlon bike legs: depends on the overall race strategy.
Yes — riding in a peloton or behind another rider reduces air resistance by 30-40%, allowing the same effort to produce 3-5 km/h faster speeds. This is why group average speeds are much higher than solo rides.
Focus on structured interval training (sweet spot, threshold, VO2max intervals), improve aerodynamic positioning, gradually increase weekly volume, and optimize nutrition and recovery between rides. Use this as a practical reminder before finalizing the result.
