Whether you're training for a triathlon, competitive swimming, or fitness laps, our calculator helps you understand your pace, plan splits, and predict race times. Enter your swim distance and time to get detailed pace analysis.
Swim pace is the time it takes to cover a standard distance, typically expressed as minutes:seconds per 100 meters or 100 yards. Unlike running pace (per mile/km), swimming uses shorter reference distances because swimmers move slower through water. Elite swimmers pace around 55-65 seconds per 100m, while recreational swimmers typically pace 1:45-2:30 per 100m.

Beginners typically swim around 2:00-2:30 per 100m (32-40 min/km). With regular practice, most swimmers can improve to 1:45-2:00 per 100m within a few months. Focus on technique before speed.
