- The measured line on most tracks is actually 20 cm out from the inner
- edge of the lane. Lane 1 may be measured differently (usually 30 cm)
- if there is a curb present. (20 cm is roughly 8 in. )

- The shape makes remarkably little difference. If, for example, the
- region bounded by the track (i.e., the "infield") is convex, then the
- calculation comes out the same. As long as the angle subtended by the
- runners, as seen from a point in the infield, is constantly increasing
- (or constantly decreasing ), the total angular distance travelled in
- 1 circuit will always be 2Pi.

- People who design XC courses have a sadistic penchant for including
- impossible hills, sloppy muddy terrain, and other terrors in their
- layouts. The runners seem to expect it! In many cases, the courses
- are not accurately measured. Another factor to consider is that only
- place counts in cross country. If Zajac were far out in front, she
- may well have "coasted" some, saving herself for another day. Finally,
- some runners are more suited to the track than to XC. Good cross
- country runners often have a lot of upper body strength. Zajac is a
- wonderfully talented runner, but she does look a bit (ahem ) frail to
- me.
