Try tool →Pace is the time it takes to cover a unit of distance, typically expressed as minutes per kilometer (min/km) or minutes per mile (min/mile). Unlike speed (km/h or mph), pace gives you a per-distance time target that is easier to use during a run.
Even pacing is the key to race success. Most runners who go out too fast experience significant slowdowns in the second half of a race. Use the race time estimates to set realistic goals based on your current fitness.
Pace awareness improves with experience. Using a GPS watch or phone app helps you stay on track during training runs and races.

A comfortable conversational pace for beginners is typically 6:00-8:00 min/km (9:30-12:50 min/mile). Focus on building endurance at an easy pace rather than speed. Most of your training runs should be at a pace where you can hold a conversation.
To improve pace, incorporate a mix of easy runs (80% of mileage), tempo runs, interval training, and hill repeats. Strength training and proper recovery also contribute to faster running. Increase weekly mileage gradually — no more than 10% per week.
Pace (min/km or min/mile) tells you how long it takes to cover a fixed distance — useful during a run for staying on target. Speed (km/h or mph) tells you how much distance you cover in a fixed time. Pace is more commonly used by runners because it directly relates to race goal times.
Hills significantly affect pace. A general rule: climbing a steep hill at the same effort level will slow your pace by 30-60 seconds per km. Descending may speed it up by 10-20 seconds per km. Trail running with elevation changes requires adjusting pace expectations.
Negative splitting means running the second half of a race faster than the first half. It is considered the optimal pacing strategy because it avoids early fatigue and allows you to capitalize on preserved energy. Most personal bests at distances from 5k to marathon are set with a slight negative split.
