Race Times and Personal Bests

Your Races screen allows you keep a log of your race results as well as doing Race Anaylses. (My SwimOptimum -> Races)

As long as you've put the correct ASA number in your profile, you can retrieve all of your official times that they've publised. Just go to My SwimOptimum -> Races and click the Import Race Time for ASA Number button at the bottom of the page.

If you want to store more data regarding your race, such as breakout times and distances for example, the Race Analysis Editor (see more about this here) will allow you to do that and keep a much more in-depth log of your races. Click the "Create Analysis" link next to an existing race time, or the Create New Race Analysis button at the bottom of the page.

If the time you entered is your new personal best for the stroke, distance and pool type, then SwimOptimum will automatically update your Personal Best record. There is no need to change your Personal Bests manually.
