Biking -
Would be nice to choose Specific activity before starting it (i.e. Mountain Biking rather than just Cycling) and have it auto add your "Mountain Bike" gear to the ride.
More sub activity specificity such as Fat Biking & Winter Fat Biking under Mountain Biking (also auto add the "Fat Bike" gear to the ride). This would allow better workout comparisons rather than comparing how my winter fat bike ride performance was vs. my summer non fat bike ride on the same trail. That said, depending on snow pack, I would also like a "Winter Mountain Biking" option when I do not use the fat bike.
Additional Activity option
Can you add Ice Hockey rather than having to use "Skating"?
Having these be available on the watch, rather than as "Other" or "Other 2" would also be beneficial. I use a Vivoactive HR, so perhaps the newer watches already allow for this.
Keep up the good work!
