Orienteering 27:26 [3] 2.41 mi (11:23 / mi)
shoes: Montrail Mountain Masochist
Training session at Ellison Park, organized by Steve Tylock. The first exercise was to compare times when doing one particular leg, where the route choices were either relatively straight but over one (or two, depending on specific choices) very significant hills, or taking a flat but longer route.
My results:
Trial 1 (over): 0.18 miles, 5:15, about 45 meters of climb and the same amount of descent. Average pace: 29:21/mile. Of some significance: The downhill on the hill just before the control was extremely steep and thus tough to make good time (was going very slowly and cautiously). Also, it was indeed possible to go around the second hill instead of up and over, and it was certainly a better route choice. Richard Burgey went up and over the first hill, and I was making much better time than he was. For the second hill, he (and Rob S.) went around, which was alongside a swamp and with no mapped trail. Richard got to the next control and I was still struggling with the steep downhill.
Trial 2 (around): 0.29 miles, 2:32, essentially zero climb, 10 meters of descent, average pace: 8:47/mile
The lessons: (1) Significant climb is to be avoided, even if it looks a lot shorter. (2) What looked like a large difference in distance (over vs around), really wasn't all that significant (about 60% longer) when considering both the climb and steep descent, and that even w/o the climb and descent, you can go a lot faster on a trail than through woods.
The second exercise was an unofficial one that Rob S., Rob H., and I did, while waiting for others to finish the first exercise. It was to compare the left route with the right route for the 8-9 leg from last year's sprint. At a quick glance, the two routes looked pretty similar. And in fact, they were. My results:
Going right: 0.12 miles, 0:55
Going left: 0.13 miles, 0:59
Only 4 seconds difference -- and that's probably within experimental error (maybe I was just running a bit harder in one case than the other, for example). So maybe a lesson in this is that if you have a leg where it looks pretty similar going right vs left, if there aren't any big differences in runnability which there weren't in this case, just pick one, don't spend even 10 seconds pondering which one may be "ideal". (Rob and Rob had similar results to mine, I believe; not much difference between routes.)
Good turnout for the training session, which was nice, especially considering that the weather was less than ideal (mid to upper 30's, a bit windy, rain forecast).
