This past weekend I setup a half marathon course using GPS coordinates. I measured and marked the course three weeks earlier but about half of the course and my marks were covered in leaves. A problem this time of year. I used a Carryall with all the course signage, mile markers and direction arrows so I did not have my bike and Jones counter to locate marks. Eight of the mile marks were visible or found by easy reference to close landmarks. Six of them had the leaf problem and no close landmark. I used the GPS coordinates that I had recorded when I measured the course and entered them into Google Maps, hit Directions and Start. When the guy in Google said I had arrived at my destination, I stopped and started kicking leaves off the trail with my foot. (Note to self – next time bring a broom or battery powered leaf blower) I found all the hidden marks easily without trying to locate some distant bridge or utility pole and then measuring to the mark. This is easy enough for any RD or course manager worth their salt to locate mile splits using only a good Smartphone.
