New Custom Course

Create your own course from a file (GPX / FIT / CSV), define segments, and get it ready for pacing or equipment optimizations.

Your course collection

Left sidebar → Your collections → Courses lists all courses available to you:

The number of custom courses depends on your plan. If you've reached the limit, Create new course is disabled — delete a course you no longer need. Your usage is shown under Quotas & limits on the start page (Plans, trial & credits 💳).

Create a new course

Load your file

Tip: The Course name is pre-filled automatically (e.g. “95 km course in …”). Replace it with a clear name, e.g., “IM 70.3 Switzerland – 2025 (Bike)”. A course name is required to save.

Optional: Trim the course

If your file contains warm-up/out-and-back extras or you want to limit your analysis to only a section of the course:

  1. Click Trim course.

  2. In Select segments to include, click Set start on the first segment and Set end on the last segment you want to keep. The selected part must be continuous.

  3. Save (or Reset / Cancel).

Segment the course

A) Choose an automatic segmentation

Open the Segmentation: Medium selector and choose:

Each option shows how many segments it creates. Once you've edited segments manually, the selector shows Custom.

Important: Choosing Coarse / Medium / Fine after manual edits replaces your segments. While you're still on the page you can get your edits back by choosing Custom in the same selector. Choose your automatic level first, then proceed to manual edits.

B) Name & set segment attributes

In the Segments table (columns: Start at [km], Distance [km], Elevation gain [m], Slope [%], Surface), click the pencil to rename a segment (max. 20 characters) and to choose the surface type. Click the ✓ to confirm.

Surface options:

Pick what best represents the road quality for that segment.

C) Edit segments (manual control)

Select segments with the checkboxes (the header checkbox selects all). An action bar appears:

Tip: You can also split at a precise position by clicking on the elevation graph and confirming Split?.
