Got bored and cut a new track into our field. Here's a map picture. The red line is the current track for the Track Attack time trials. The green line represents the new one. The red dotted line is an adjustment I made to the existing perimeter track. Don't worry, I still have the path for the old track in place to use for the Track Attack comparisons.
Here's the map:
Here are a couple of pics of the track as best I could get them:
