Athens Authentic Marathon pace calculator and spectator planner

Enter a start time, goal finish and pacing strategy for the Athens Authentic Marathon to get a grade-adjusted plan. The course runs from 7m to 249m above sea level, with a sustained change in elevation that affects pacing. This is a point-to-point course, so the finish window matters most for spectators. Tap anywhere on the course map to see when your runner is predicted to pass, or enter a clock time to see where they will be.

The time you cross the start line, not the gun time. Add your wave/corral delay.

In large races, later waves can start 20-40 minutes after the gun.
