Expert foot-O course by Becks at Gay City, straight line distance 5.6km. Bit of an adventure at #6, crossing the stream north of the rocks and cursing the saplings before realizing those were the wrong rocks. Must have left the trail at the wrong angle and took a bearing from the north end of the wrong hill. Oh well. Probably faster just to follow the trail all the way around... Then #10, which was on a different cliff than the one circled, but didn't cost me much time, especially with Lyn's coaching. :-) Nice circuit of the park.
One fall, punctured my map case and scraped my knuckles; and one almost-fall which may have overstretched muscles that didn't need the extra extension. Back was not a problem at all, though I wasn't running full speed either.
2--Good leg; used compass, crossed walls where I expected to, hit stone wall N of control just between the two reentrants (the one with the marsh, west of the flag, was off to my right; Gail was off to my left :-) ).
7-- went west of the marsh after taking the bike trail part of the way around. From NW side of marsh, angled NE to the main trail through lovely fast woods, then off the trail near the hilltop; north and over the little kidney-shaped formline hill.
9--was a bit farther south of the line than I thought I was; dipped down the hill early but saw large cliff on other side of reentrant and headed back up (fewer downed trees and less side-hilling)
