I have a suggestion for improving how Garmin Connect handles Triathlon activities. Many triathlons include a significant run from the swim exit to the transition area, and have the timing mat positioned at the transition area entrance. So our "swim" time ends up including a significant amount of running. If we press the Lap button on our devices at the same time we cross the timing mat to keep the results aligned then that screws up the Open Water Swimming metrics in Garmin Connect. So I would like to recommend that Garmin add a feature to mark part of an Open Water Swim inside a Multisport activity as being actually a Run after the activity is over.
The other alternative today is to press the Lap button as soon as I exit the water, but then my times recorded in Garmin Connect for the Swim and T1 won't match the official race results.
