Enter your swim distance, time (hours, minutes, seconds), and choose yards or meters — the Swimming Pace Calculator returns your pace per 100m or 100yd, your speed in m/s, and total time in decimal minutes. Great for triathlon, open water, and pool training.

Swim pace is the time it takes you to swim 100 meters or 100 yards. It's the standard unit swimmers and coaches use to plan training sets, set race targets, and track improvement over time. Knowing your pace helps you swim at the right effort level for each type of workout.
Divide your total swim time (in seconds) by your total distance, then multiply by 100. For example, if you swim 1500m in 27 minutes 30 seconds (1650 seconds), your pace is (1650 ÷ 1500) × 100 = 110 seconds per 100m, which is 1:50 per 100m.
Beginner recreational swimmers typically average 2:30–3:30 per 100m. Intermediate swimmers often hit 1:45–2:30 per 100m, while competitive club swimmers can go under 1:30 per 100m. Elite open water and triathlon swimmers typically aim for 1:10–1:25 per 100m.
Most coaches recommend a time trial every 4–6 weeks to track fitness progress. Testing too frequently can disrupt training, while testing too infrequently means you may be training at the wrong intensity. A 400m or 1000m time trial is a common benchmark set.
Pool pace is a useful starting point for open water, but expect to be 5–10% slower in open water due to no walls to push off, sighting interruptions, waves, and wetsuit fit. Adjust your target pace accordingly when planning an open water or triathlon swim.
Shorter pools (25m or 25yd) provide more turns per 100, and each turn push-off briefly boosts speed. This means 25m pool paces can appear slightly faster than 50m pool paces for the same fitness level. When comparing times, note the pool length used.
1 yard equals approximately 0.9144 meters. US pools are commonly 25 yards, while international and Olympic pools are 50 meters. This calculator lets you select your unit so pace is always shown per 100 of the same unit you enter — keeping comparisons accurate.
A common method is to base training zones off a CSS (Critical Swim Speed) test — typically the average pace from a 400m and 200m time trial. Your aerobic base pace is usually 10–15 seconds per 100m slower than CSS, while threshold work sits near CSS pace.
