I am seeing if the activity can be imported to other watches, and if somebody could upload it (you can insert files in comment I believe) that would be greatly appreciated.
To do this, you need to plug in your Venu 2 to your Windows device, open the file explorer > Venu > Primary > Garmin > Sports and then find the HIIT activity.
