In fact, he never seemed to like going in the pool in itself.

The average horse makes a lap in about 34 to 35 seconds. Particularly fast horses makes it in the 20 seconds range. Hishi Miracle does it in 48 seconds.

They tried all the means possible to make him advance in the pool.

"At the beginning, Hishi Miracle was really serious going into it but now, he seems to be more resigned to it. He gets slower every time he swims (laughs)" Quote from Yushun vol. 2004.8.

Incidentally, after going at the pool and into the hot bath, he was often in the mood for yawning, as many pictures and said article showed.

So it seems unlikely that he actually hated going into water.

Also incidentally, Oguri Cap, who was also infamous for being a poor swimmer, also loved going into hot baths. (From KK best seller Marugoto Oguri Cap Densetsu) "The Complete Oguri Cap Legend"
