Still get sticky!
You can now manually mark a planned activity as done, so if you didn't have your watch, you can still get sticky!
Just head to your training calendar, select the planned activity and hit 'Mark as Done'. You can then enter the time, duration and effort involved.
Perfect for strength sessions, or if your watch dies on you!
P.S. The option isn't available for future planned activities... so you can't cheat!
