Reasons to not use a garmin "workout" when racing

1- exact distance may not get you to the finish line. Ie my garmin said 13.22 at the finish. Had I been using a workout it would have ended before I crossed the finish line. I think this distance variation has to do with the official distance being based on always running on the inside of every turn.....maybe.
2- not sure how a workout would "react" when I lost signal in the tunnel
3- I think the "lap pace" alert at the end of each mile is more meaningful than the "workout" slow down and speed up alerts every time you are out of your target range especially because you inevitability are much slower during water stations
I still love my 405cx. It helped me shave 16 minutes off my half time. Now let's see if I can take another 16 minutes off!
