This quest is another part of the baron's story about his meeting with Ciri, which he will tell you at the end of the Family Matters quest.
The baron treated Ciri like a daughter - no, better - for slaughtering a boar is sadly a delight few fathers think to share with their daughters. His men took an immediate liking to her as well, mainly due to her hunting prowess and passion for horses. One evening, as they were celebrating a successful hunt around a bonfire, Ciri proposed a wager: if she beat the baron in a horse race, he would give her a mount of her choosing. The baron accepted the challenge.
