It's perfectly reasonable to award a high roll with extra movement, but it's completely up to DM decision whether that should happen on a success, as well as what you think should happen on a failure.For your specific scenario, in-story, perhaps she exerted herself to sort of jump-climb up the tower (if you've seen climbing in Breath of the Wild, you might know what I'm describing) and scaled the tower more quickly than she normally would have otherwise. If it didn't take away much from the story of the game, probably fine not to worry about too much but be prepared for how you want to handle the same potential scenario in the future.
