Why you're probably doing double-threshold training wrong

Thinking about trying the 'double threshold' day you've seen the pros do? 🇳🇴 Hold up! The biggest mistake runners make is treating it like two separate, gut-busting workouts. That’s a fast track to burnout, not a new PB. 🥵 The secret isn't about killer intensity. It's about **accumulating more *controlled* time** at that "comfortably hard" threshold pace. The goal is to build your aerobic engine without wrecking your body. The golden rule: You should finish the morning session feeling strong and like you could do more. If you're totally spent, you've gone too hard. Train smarter, not just harder. #DoubleThreshold #RunningTips #RunSmarter #UKRunChat #MarathonTraining #WhyRun
