Race Power Calculator and Event Planner

Stryd's Race Power Calculator and Event Planner is intended to help you set an achievable target power or target time and to see what the possible outcome might be as your race day approaches. There are many factors that affect this calculation, and certain criteria must be met to have an accurate estimate (see the FAQ below).

Stryd's new race power calculation can be used in one of two ways.

1. Via the mobile app by creating an 'Upcoming Event' on the 'Profile' tab
2. Via PowerCenter 'Analytics' tab.

Each platform provides a different experience.

Mobile allows you to create an event that you can save to your calendar in which you'll have a race card with your 'recommended power and corresponding 'estimated time' which updates based on your last 90 days of running activity as the event approaches (must choose 'recommended power' for it to auto-update).

PowerCenter is meant as more of an exploratory tool. You can select a preexisting course or upload a new one to see how you might perform on race day. The PowerCenter calculator allows you to play with every variable including 'training at' parameters vs 'racing at' parameters. Explore how you might race given differing environmental factors and variables. 

You can upload a course using PowerCenter. The course can be a FIT file from a previous run or you can upload a GPX file. The GPX file must have a timestamp. Typically, mapping apps that let you create a GPX file cannot be uploaded. Many apps like Strava and Garmin Connect let you export your course as a valid GPX file that can be uploaded.

Stryd’s ‘Race Power Calculator’ uses your previous 90 days running activity to recommend a ‘Target Power’ or ‘Target Time’ for both generic flat courses and real courses (from an uploaded course profile). There are many factors that go into Stryd’s calculation. There is a list of frequently asked questions.
