While I understand this is shown in several countries, the producers need to remember that many here in America have *no* concept of metric measurements. The teams travel 40 km, or climb up 300m. Huh? We can convert these measurements into decimal, but that takes too much brain power. Why not simply give these measurements in both metric and decimal? Easy to do, for example, "teams travel 40km or how ever many miles" that is. Metric has *zero* meaning to many of us.
