The question is whether Jeff, the meet director and day 2 course setter, has things under control. (I think he does, though he's still tweaking his courses and the map.). As to what course to run: I think you should run blue, given your prodigious training. And the field's wide open now that Will has forsworn orienteering for the rest of the fall.
Perhaps some information on course lengths would facilitate the decision. We'll just assume that climb = "lots".
Course information should show up on the website by the weekend. Day 1 it's GreenX 4.9k, 275m; Red 6.6k, 360m, Blue 8.3k, 455m. Day 2 courses are a bit longer, but with less climb and faster terrain.
