it's not part of her chain so most runs won't trigger it at all. it's only -20 energy, and both choices also give +25 in stats. the mood down one is usually worth it, you're not training guts directly but it's still valuable for the first few hundred, and in long races even past 400. it's not an amazing event, but especially paired with Kitasan you'll be fine because you'll get free mood ups during the run.
