The student stands in the stable stall, shovel in hand, and considers a 21-year-old's lifestyle choice.

Responsibility comes with the gig, Amy Hudlemeyer says. Paps, the sorrel who loves to run, never cleans up after himself.

She puts the scoop to work on horse droppings, not the typical university experience. Only gloom commends the afternoon, and a cold rain taps hard against the metal roof.

It's not difficult to imagine fellow students with different pursuits this gloomy day.

"A lot of people, they take naps," she offers. "They have a lot more social life than I do."

Her musing is good-natured, not at all a lament. Ms. Hudlemeyer has spent most days since age 12 with her boots on straw. A barn's routine and rigor seem to her second nature and not unpleasant.

Carve out three hours many days, time to attend to Paps and Rastus, her palomino in the adjoining stall, take a ride and do the required cleaning. At Northwest Missouri State University, her classes lead to a degree in unified science education, maybe a step toward veterinary medicine.

But Ms. Hudlemeyer's competitive temperament, the one that leads to the lightning starts and jarring turns of barrel racing, requires a cross-species telepathy. To do this well, she and a horse must think with one mind.

Training's repetition, the exercises in rider balance, weight shifts, rein use and a dozen other horsemanship techniques, comes down to 17 seconds, give or take, in a rodeo arena, a champion's margin being measured in fractions of a second.

"Your horse and you are a team," the rider says. "If you don't get along, your run's not going to be pretty."

Growing up in Gallatin, Mo., Amy got her first horse nine years ago. Her education in showing the animal led to an impatience with the activity and a recognition of the speed beneath her. As a high school sophomore, she and a bay named Annie began racing.

Those who had seen the smallish mare questioned Amy about this conversion. But the rider found heart and personality, along with a fundamental soundness, make a good barrel horse.

Barrel racing involves horse and rider negotiating a clover-leaf pattern around three barrels that can be touched but not toppled. Teaching herself, Amy began getting competitive times, but not great ones. (She and Annie did better at pole-bending, a rodeo event whose serpentine course also demands superb horsemanship.)

Gene and Carrie Crouse, Gallatin residents and rodeo regulars, spotted the teen's barrel racing potential and offered their help. Amy learned the nuances of when to stand, when to lean, when to balance with the legs. With Annie, the rider learned to "keep out of her mouth," avoid an overuse of the reins.

Her performances improved. In 2007, she became the reserve barrel-racing champion of the Missouri-Kansas Youth Rodeo Association. Lessons continued to be hard-won.

On the verge of qualifying for the nationals in pole bending, Amy saw her horse hit a hole, flip and step on her on a muddy course. The disappointment was worse than the pain.

"You can't take everything personally," she says, recalling the spill. "You have two personalities running at one time."

So many moving parts, so many chances for mishap or a slow time. But the rider knows those moments, approaching the first turn, the "money barrel," when every move seems in sync. "You pretty much know after the first few seconds if you have a chance," she says.

As an honor of a different sort, Ms. Hudlemeyer became Miss United Rodeo Association of 2008, a yearlong splash of pageantry of her resume that didn't supersede time required in the stables.

As she scoops, others at the university barn do the same, the work far from competition and an arena's applause. They also balance the requirements of horse tending with class work. Ms. Hudlemeyer plans for a busy week in the offing.

"I have lots of tests," she says. "I probably will do nothing but study and clean stalls."

It's a different culture, the rider concedes, a college life revolving around a horse.
