I've always been a fan of a more aggressive taper. I cut my mileage by 75% 7-10 days out and focus on rest and visualization. I'd rather feel fresh and ready to go on race day, even if it means sacrificing a bit of fitness. Plus, it's not like you're going to lose that much fitness in a week or two. It's all about feeling confident and ready to crush it on race day.
I'm a numbers person, always have been. I set a pace and try to stick to it, even if it kills me. But, I've learned that it's not always about hitting the exact split. If I'm feeling good, I'll push it. If I'm struggling, I'll back off. It's about finding that balance between pushing yourself and not burning out. Tempo runs are supposed to be hard, but they shouldn't be miserable.
Maybe, but let's not forget it's still a niche sport for masochists.
