For you long time racers this may come off as being too long and too boring, maybe too much racing 101 that you already know. This is for the guys who race from May through October (at least in the south) and are disappointed with their runs and don't really know how important DA is on their times.

Here is a top notch DA (density altitude) calculator. Racers, who race for time slips, need this around on their cell phone or laptop. Racers who race for time slips don't pay attention to reaction time.

Just go down to the left and change your track, then change the date, scroll down and you will find the DA.
