Taking eight weeks to boost your fitness is key for how to run a faster 5K in the new year. To PR in a 5K, you still need lactate threshold (i.e., half-marathon pace) work, because that’s what gets you to 4K. But crushing that final K requires developing the anaerobic system with 5K velocity work and more aggressive strength training, says coach and Olympic Trials finalist Rebeka Stowe. “You’re going to see more varied work here—change of pace, change of effort—just because you want to start understanding what 5K pace feels like, and it’s not a comfortable place.”
