In the meantime I figured out that you can delete trainings from the list (the delete option is the last entry in the list). Removing all items was a a bit tedious but worked. I hope that they are not back after next update.
enable user to reduce selection list for training types
my rungps asks me on startup about the type of training. I would like to have a possibility to reduce list of training types displayed. In practice I just need 2 types and it is a bit tedious to switch between bicycle riding and jogging in the current list..Making this configurable would increase the usability at least for me significantly.
