Hello,

i use kiprun racer to generate my running program and export each session on my garmin forrunner 235.

As i can't modify and personalize the session on kiprun, i would like to modify it on my garmin but i don't kown where is the session file and how modify it

I found files in GARMIN\Workouts but not sure it's that.

Can you help me ?
