You've just registered for a race that is a longer distance than you've ever ran before. Maybe it's a 10k, maybe it's a half marathon, or maybe you've just signed up for your first full marathon. Whatever the distance, knowing your target finish time and pace is critical to crossing the finish line with a smile.

The race finish calculator below lets you enter a finish time and distance of a previous race or training run and projects what your finish time and pace will be at a longer distance. This calculator is based on the well known fact that a runner's pace slows down at longer distances. Once you have your finish time and pace you can use that info to create a training plan with confidence you will reach your target time.
