Watch pace calculator

Plan your marathon paces per 1, 5 and 10 km with the reality of the race in mind. Takes the course elevation into account, plus the fact that your watch usually measures a few metres longer than the official course.

How to use it: enter your target time. You get a total pace and a safe-zone pace, which assumes you need to average 2 seconds per km faster on the watch to hit your official chip time. Then you get split suggestions based on the course profile. These are just suggestions. Make your adjustments to make it your own.
