About SwimCalc Pro

SwimCalc Pro was built by swimmers, for swimmers. Whether you're a competitive age-grouper, a masters swimmer squeezing in early-morning workouts, a triathlete training for your first Olympic distance, or a recreational swimmer looking to improve your fitness — you need tools that actually work.

What We Offer

We've built over 30 professional swimming calculators covering everything from split times and stroke rates to hydration needs and lactate threshold training zones. Each tool is designed to give you actionable numbers — not just raw data, but insights you can use in your next practice or race.

Expert Guidance

Our articles are written by coaches and experienced swimmers who understand the demands of the sport. We cover freestyle technique, training methodology, recovery strategies, nutrition, and the mental side of racing. Every guide is grounded in practical experience, not generic fitness advice.

Why We Exist

Swimming is one of the most technically demanding sports. Progress requires tracking the right metrics — pace, stroke count, heart rate zones, caloric expenditure — and knowing what to do with them. SwimCalc Pro exists to give every swimmer access to the same calculation tools that coaches and elite athletes use, completely free.
