About MarathonCalculator.com

At MarathonCalculator.com, we believe that running is more than just a race—it’s a journey of personal growth, perseverance, and achievement. Our goal is to provide runners with the tools and inspiration to set, track, and conquer their marathon goals, whether you’re chasing a personal best or simply finishing your first race.

Founded over 16 years ago by a dedicated runner who has completed more than 20 marathons, MarathonCalculator.com was born from a passion for helping others. We know that every finish line represents countless hours of hard work, and we want to be part of that journey. Our free, easy-to-use tools are designed to help runners plan their races, track their progress, and stay motivated.

What drives us is a commitment to encouraging others to believe in themselves and push past their limits. This site is more than a calculator—it’s a community built on the idea that we can all achieve something extraordinary when we set our goals and go after them.
