Split Infinity by Piers Anthony

competed, riding a really good animal. He saw, from the periphery of his vision, the constant rocking of the backs of the other horses, their jockeys floating above them, so many chips on the torrent. The audience was a blur, falling always to the rear, chained to the ground.   Reality was right here, the center of action, heart of the drifting universe. Ah, essence!
    Battleaxe liked room, so Stile let him lunge forward, clearing the press as only he could do. Then it was just a matter of holding the lead. This horse would do it; he resented being crowded or passed. All he needed was an understanding hand, guidance at the critical moment, and selection of the most promising route. Stile knew it; the other jockeys knew it. Unless he fouled up, this race was his. He had the best horse.
    Stile glanced back, with a quick turn of his head. His body continued the myriad invisible compensations and urgings required to maximize equine output, but his mind was free. The other horses were not far behind, but they were already straining, their jockeys urging them to their futile utmost, while Battleaxe was loafing.   The lead would begin to widen at the halfway mark, then stretch into a runaway. The Citizen would be pleased. Maybe the horse had been primed by the attention this morning, the slight change in routine, the mini-race with Molly. Maybe Stile himself was hyped, and Battleaxe was responding. This just might be a race against the clock, bettering this horse’s best time. That would certainly please the Citizen! But Stile was not going to push; that would be foolish, when he had the race so readily in hand. Save the horse for another day, when it might be a choice between pushing and losing.
    He was a full length ahead as they rounded the first turn. Battleaxe was moving well indeed; it would not be a course record, but it would be quite respectable time, considering the lack of competition. Other Citizens had made fabulous offers for this horse. Stile knew, but of course he was not for sale. The truth was, Battleaxe would not win races if he were sold—unless Stile went with him. Because Stile alone understood him; the horse would put out gladly for Stile, and for no one else.
    There were a number of jockeys who could run a race as well as Stile, but none matched his total expertise. Stile could handle a difficult horse as well as an easy one, bareback as well as saddled. He loved horses, and they liked him; there was a special chemistry that worked seeming miracles on the track. Battleaxe had been a brute, uncontrollable, remarkably apt with teeth and hoof; he could kick without warning to front, side and rear. He could bite suddenly, not even laying his ears back; he had learned to conceal his intention. He had broken three trainers, possessing such demoniac strength and timing that they could neither lead him nor remain mounted. Stile’s employer, sensing a special opportunity, had picked Battleaxe up nominally for stud, but had turned him over to Stile. The directive: convert this monster to an effective racer, no effort spared. For this animal was not only mean and strong, he was smart. A few wins would vastly enhance his stud value.
    Stile had welcomed the challenge. He had lived with this horse for three months, grooming him and feeding him by hand, allowing no other person near. He had used no spurs, no electric prods, only the cutting edge of his voice in rebuke, and he had been absolutely true to this standard. He carried a whip—which he used only on any other animal that annoyed Battleaxe, never on Battleaxe himself. The horse was king yet subject to Stile’s particular discipline. Battleaxe evolved the desire to please Stile, the first man he could trust, and it did not matter that the standards for pleasing Stile were rigorous. Stile was, the horse came to understand, a lot of man.
    Then came the riding. Battleaxe was no novice; he knew what it was all about, and tolerated none of it.   When Stile set up to
