Just posting this here in case anyone feels like watching it. Didn't really have much to say about the run so didn't do a voice over. At the end I discussed some of the legs with a coach.
1. take the video with a gopro and record track with a gps watch 2. make a 2D rerun replay with map image file and gps track 3. record the 2D rerun track in real time with a program like OBS 4. in a video editor (eg: adobe premiere elements) sync up the headcam video with the 2D rerun
