I did a triathlon yesterday and uploaded the data to Garmin Connect today. Can I segment the race in any way so I can analyse data for the swim, T1, bike, T2, run? Should have I marked my splits manually during the race?
It seems that it would have been easiest to use the lap button to mark off each segment of the race as a lap. That said, if you have a license for the Fit File Repair Tool, you should be able to edit the activity data as you see fit.
If you can attach the activity file in a reply to this post and let me know where you need (time wise) the 'segments' put in, then I will be able to do that for you using the Fit File Repair Tool.
