A 46 Second Mile PR in Three Months

Most runners chasing a mile PR do the same thing: more mile repeats, faster, until something hurts.

One of my athletes, Phoenix, just took 46 seconds off his mile. He did it the day after running 18 miles. Three months of work, three things in it.

First, we made him durable. Most athletes are nowhere near the weekly mileage they need, and then they wonder why the speed will not hold. It does not matter if the race is a mile, a 5K or a 10K, you need an aerobic engine underneath it. The more durable you are, the more speed you can produce and the longer you can hold it late. For the mile block we kept his volume around 50 to 60 miles a week. Not huge. Consistent.

Second, we trained power, not just endurance. Explosive band work, sprint specific training, plyometric movements. Running is not only about the road and your lungs. It is about how much force you can put into the ground to propel yourself off it. That comes from weights and explosive movements, and a meta-analysis in trained runners found strength and plyometric work 2 to 3 times a week for 8 to 12 weeks improves running economy.

Third, we fueled the work. Volume stayed the same, carbohydrate intake went up significantly. More quality training requires more fuel. Under-fueling is one of the biggest reasons runners plateau, or never get the marathon PR, or keep getting injured. The RED-S consensus is not a niche problem, it is most of the injured runners I talk to.

None of it came from one workout. Phoenix did not miss a workout and did not miss a rep for three months. When he was tired he texted me and we moved things around. That is the whole method.

Give yourself three months of that and go run a mile. Because a mile PR does not come from mile repeats.
