Our XC course went past our soccer fields... A few times, an XC meet would be the same time as a soccer game, and obviously the cheerleaders had no idea, because nobody cared about XC. So we'd be running by and then they would start cheering for us through the 10m stretch where they were standing, which was funny considering they probably didn't even know our names or how far we ran or anything...
But I think it would be awesome for a school to actually have cheerleaders "assigned" to XC, and actually get to know the sport and the team a little bit. Nothing wrong with that!
