How long it will take to finish a race has an impact on some important decisions. Pace, nutrition, attire, and even your playlist can be affected by how long you will be out there running.

Recognizing the value of this information, Garmin and Firstbeat have taken strides in the effort to provide reliable race time predictions you can trust.

Your ability to produce energy aerobically, measurable in terms of VO2 max, is a significant factor in your race performance. This knowledge, along with real-world data about the sustainability of effort across various intensities, provides the foundation of your predicted finish times for various distances.

The reliability of your predicted finish time is enhanced by analyzing trends in your training load and mileage data for the last few weeks. This analysis includes special consideration of all different types and frequencies of runs you performed along the way.
