Another route test


I did another route test today. The map shows the four options I tested (click for higher resolution).

Take a look at the leg. Put the different routes in order (fastest to slowest) and post your guesses using comments. I'll post the answers, based on my times, in a few days.

The leg is about 800 meters. The contour interval is 3 meters. The hills aren't as big as they might look. The footing was ok, but not perfect. We've got a bit of snow falling and the trails, especially where they've got ice on them, were quite slick. The forest is mapped as white, but would probably be a light green in most areas. The rough open is mostly grass above your knees. You can usually get through the rough open quickly by following deer trails, though the deer trails don't always go exactly where you want.

For an added challenge, you can guess the times. To get you started, I'll tell you that the slowest time was 7:55 (I've rounded all the times to the nearest 5 seconds).

I'm doing this sort of training to try to improve my ability to look at different route choices and estimate time differences. I'd like to be able to look at a leg and make decisions like, "I'll take the easy trail route, it'll cost me 20 seconds, but I'm willing to give that time up in order to run on a road and get a chance to plan the next couple of legs."

I also think that testing routes like this is a good way to use a familiar map.
