I'm actually commenting on this thread purely to enforce the accuracy of the statement made by "TTHS", and to partially refute this point.
I am of Chinese descent and attended high school in a suburb of Northern Illinois with a 20% Asian-American population (I can provide a link for proof if anyone would like it), and approximately 30-35% of our high school cross country team during all four years I participated was Asian-American.
The poster "TTHS" basically hit the nail on the head for describing a HUGE proportion of Asian-American cross-country athletes who actively seek to improve themselves in the sport. I can attest that I personally felt this way about cross country during my freshman and sophomore years, and that the majority of the Asian-American runners who actually "tried" during practices and races did to some extent as well. And let me point out here that I am specifying runners who "TRIED" during practices and races. I have no idea as to whether or not this was true for the guys who didn't put any effort into running to begin with.
Basically, I would run all my practices faster than many other runners on the team, but come race time, 5-6 of them who would always run slower than me in practice would always manage to beat me, sometimes by as much as 30+ seconds. For example, one of my favorite workouts was 12 x 400m repeats with a 200m jogging recovery in between each. Midway through my sophomore XC season, I could perfectly hold the 400s at 73-74 seconds each, while other guys were back at 76-78 seconds per rep. Come race time though, I would run a 17:20-17:30 while some of them would manage to break 17:00. This kept happening all throughout my entire freshman year, and almost through the whole sophomore cross country season. All but two of the serious Asian runners on our team had the exact same problem.
Our head coach was very new at the school, was 29, and had only been coaching high school cross country for 3 years when I started my freshman year. He had basically been trying to figure this out the entire time, and finally managed to do it during my sophomore season. In short, I was really nervous about my races, as were the other guys who had this problem. The best way I could describe it is that I would try and plan out the entire race in my head, start out at some pace that usually would not align perfectly with my imagined pace, hear my first mile split, panic that I had gone out too fast or too slow, panic the moment it started getting hard to hold the pace, and then crash and burn over the second half of the race.
What my coach did for us is that finally fixed it was that he basically turned the entire race into a set of 400m repeats by having a bunch of the injured guys and some members of the girls team stand EVERY 400m along the course and give 400m splits to us on the way so that I could adjust my pace accordingly. The first time he did this, I ran 16:48, and after that 16:28 on our home course.
Basically, it was just like what "TTHS" said about how Asians like having large amounts of control over our performance. I would always psych myself out during every race when I heard the splits at each mile because something would always be off with respect to my plan, but once I got feedback every 400m, the whole panicking problem basically fixed itself.
"stereotypingisdangerous". You probably do not understand this because you are not an Asian-American, but in this case, the stereotyping is for the most part correct. An enormous proportion of us have parents who basically drill us in laborious memorization tasks related to math, geography, etc. from the time we are children. In fact, I was taught how to perform long division in kindergarten, and was forced to spend several hours each week before first grade repeatedly working on "division problem sets" with my mother watching. Tests, even in grade school, always put some degree of pressure on me since my parents would often be upset with anything that wasn't up to their standards.
The result of this is that, similar to what "TTHS" described, we frequently view many aspects of life as "prepare for the test and take the test". We often try out for sports like cross country because it's no cut, and requires virtually no athletic coordination to succeed in. All we have to do is put one foot in front of the other over and over again, which is considered a repetitive chore for most people, but something many of us tend to be much more comfortable with, since we grew up performing repetitive chores. Since we also grew up being overwhelmed with a large wave of dread every time the tests came around, that carries over too, and race day is basically the day we hate the most.
To the OP, I apologize for the long-winded comment, but if anything, just listen to what "TTHS" said and find some way to try and relieve the nerves of your runner by making the race itself seem more like a practice. It worked for myself and a dozen or so other guys experiencing the same problem while I ran in HS, and since your runner's problem seems virtually identical to our problem, I'm certain it will help to some extent.
