What are the most accurate devices/sources to get my .GPX or .FIT file from?

Achieving the best results from Best Bike Split is dependent on having a quality .GPX Track or .FIT Activity file with accurate elevation data for our math and physics model. Below is a guide to help you select the best .GPX Track or .FIT Activity data to upload to the system.

• Bike computers with a barometric altimeter, including current Garmin Edge, Wahoo ELEMNT and Hammerhead Karoo models
  

• GPS watches with a barometric altimeter (most Garmin Forerunner, Fenix and Epix models, and similar)
  

• GPS watches or bike computers without a barometric altimeter
  

• Phone apps (phone GPS elevation is often inaccurate)
  

• The Course Builder is Best Bike Split's built-in tool for creating custom cycling courses directly in the app. Instead of using external tools and importing files, you can draw your course on an interactive map with automatic road routing, elevation data, and surface analysis all optimized for Best Bike Split race planning.
