How does Best Bike Split classify a course?

Best Bike Split uses a two-step process to classify a course based on elevation gain, distance, and the frequency of categorized climbs.

  • First Pass - In the first pass we look at elevation gain to course length ratio. The total elevation gain (in kilometers) is divided by the total distance (in kilometers) and multiplied by 100 to calculate the elevation ratio. Based on this ratio, the course is initially classified as:

    • Flat: Elevation ratio < 1.5

    • Rolling: Elevation ratio between 1.5 and 4

    • Hilly: Elevation ratio between 4 and 7

    • Mountainous: Elevation ratio ≥ 7

  • Second Pass - In the second pass we check climb frequencies. The course classification is adjusted based on the number of categorized climbs (HC, Cat1, Cat2, Cat3, and Cat4). This helps to fine-tune the classification by taking into account the frequency of significant climbs.
