I would like to see paddle sprots added as a workout type. This workout type would be able to cover

Outrigger Paddling
Standup paddleboard
K1
C1
Kayaking
Canoeing
Dragon Boat
Whitewater Rafting
Surf Ski
Paddleboarding

Training Peaks is used for more than Bike, Run, Swim. I heard a podcast with Dirk Friel recently and he stated "Other" was the largest growing sport sector currently. Adding a general "Paddle Sport" would allow you to enable a lot of functionality across all of the sport types I listed making TrainingPeaks great for water endurance sports.

Also to note, your competitor Final Surge, has already addressed this for the outrigger community by creating a sub sport for cycling, which includes "OC1" and "OC6." With OC1 standing for a 1 person outrigger canoe, and oc6 standing for a 6 person outrigger canoe.
