If you will not be in Boston this weekend you can still row the Head of the Charles (and other races) by using a program called ergTour. It uses the Concept II Model D rowing machine to guide Google Earth along the race course.
1.Start Google Earth and let it initialize. It is very important to do this first.
2.Connect the PM3 to the PC via USB cable.
3.Select your workout.
Note: It is very important to have the Concept II PM3 connected before running Erg Tour.
The program is free but will run for 45 days only.
