The Athletes Diary 3.2.7
The Athlete's Diary is a special-purpose database program, designed explicitly for athletes.
You can log your training, view it in a a variety of formats, and analyze it to your heart's content.
You can also use the software to plan your future training. The Athlete's Diary is a stand-alone program - not a template for any other program (Excel), nor based on any "database engine" (dBase).
Because of this, all three versions are quite small, extremely fast and highly attuned to the desired task.
