S-shaped route If you are planning an S-shaped route, take a closer look at the point of maximum deviation on the first curve — the point from which you intend to return toward the leg line. (point A on the figure) From this point, mentally move the next curve to the opposite side (red line). The S-shaped route can then be viewed as one larger curve. This may reveal another option: from the same point, you might be able to run in the opposite direction along a better arc. There is a more general principle behind this.

At that moment, your route choice should be reconsidered from your current position . A good example comes from the recent Estonian Long Distance Championships, from the women’s elite course. The winner, Marianne Hauge, chose an S-shaped route , while the silver medalist, Sig...
