Can't be done. You can only put in increments of 1 hour (whole numbers only). I suppose since goals are at least a 7 day period, then minutes would not be needed.
I have always thought that on increasing training, one should not increase by more than 10% per week, perhaps 15 min intervals may be more appropriate!
Good point!
Just enable minutes here, this is just bad programming. for smaller (timewise) activities this is a MUST
