How do I setup the fields and tabs for fields like workout code or sport

In the Options/Preferences panel for GC (tools options, or preferences on a Mac) you select Settings->Ride Data. Here you can define screens and fields and their associated types. If the column 'screen tab' is blank the field will not be displayed.

There are a number of 'special fields' which have a pre-defined meaning. You do not have to use them, but they may be useful to some users, they are:
  • Athlete - the athlete name (corresponds to the directory name)
  • Change History - log of changes made to file (updated when you save).
  • Device Info - If the ride file has device information it is stored in here
  • Dropouts - Used by Tools->Fix Gaps to count samples missing in gaps
  • Dropout Time - User by Tools->Fix Gaps to count time elapsed in gaps
  • Filename - The full path name for the file
  • GPS errors - Used by Tools->Fix GPS to record errors
  • Keywords - reserved for 'tagging' rides
  • Objective - Used by the PWX file reader to store from PWX ridefile format
  • Spikes - Used by Tools->Fix Spikes to count the number of spikes in a file
  • Spike Time - Used by Tools->Fix Spikes to record the time elapsed during spikes
  • Sport - Used by the WKO file reader to store the WKO+Sport field
  • Start Date - The date the ride started
  • Start Time - The time of day the ride started
  • Temperature - Used by the BIN ride file reader to store from Joule files
