Since Garmin Training Center stores your data in a sqlite file, it’s now now easy to sweat while analysing your workouts.

• Usually, a *.tcd file is stored in

C:\Users\*USER*\AppData\Roaming\Garmin\TrainingCenter\Backups. You can request a new backup save via the File menu in the software.

• the backup located in the previous section is actually a SQLite file that we’ll feed to the R/graphs.R script.
• fill in your records in the R/load.R file - table Records

Here’s a few examples based on the data from a person regularly training (running, biking, and swimming). Your imagination is the limit.

Plots similar to the one on Garmin Connect.

The plots on this section outlines the PBs for Running and Biking (the red dots).

• Garming TC does not name on “other” activities. Those can include walking, swimming, etc
• Accuracy of the HR monitor can debated, especially after 1 year usage.
• this code is a bit old and lacking some styles that I learned later, namely pipes and javascript libs.
• Some plots needs the temperature during the activity. Look for a nearby temperature temperature station with open data. If you’re in the US there should be plenty.
