Incredible running calculator – estimate race performances.

I plugged in my latest 5K time, and it correctly predicted my latest 10K time, and came within 5 minutes of predicting my 10-mile time in my last race.  As for predicted/recommended times for my 400-meter sprints, I’m running them close to 30 seconds faster than the calculator says, which is cool.  Unbelievable!
