Could a faster mile start with a quick brain drill instead of another sprint? New research suggests that, for some recreational runners, the mind may need a warmup just as much as the legs do.
A recent study found that runners who added short cognitive tasks to a normal physical warmup completed one-mile time trials about two to three percent faster than when they warmed up with jogging, stretching, and sprint drills alone. That may sound small, but for a runner chasing a personal best, a few seconds can feel huge.
Brain before speed
The study looked at a simple idea with real-world appeal. Before running hard, athletes usually prepare their muscles, lungs, and joints, but they rarely do anything specific to prepare the brain.
That is where brain priming comes in. In plain terms, it means giving the brain a short, focused challenge before exercise so it is more ready to manage attention, effort, discomfort, and decision-making.
A team from the University of Birmingham and the University of Extremadura in Spain tested 25 recreational runners over three track sessions across two weeks. The runners had an average personal best of about six and a half minutes for the mile.
How runners were tested
Each runner completed a one-mile time trial after one of three warmup routines. One was a standard physical warmup, while the other two combined physical preparation with cognitive tasks of lower or higher difficulty.
There was a small twist that matters. The runners were told to run “on feel,” without using a watch or pacing device to guide their effort, which made the test closer to the way runners often judge pain, rhythm, and pace in the moment.
The physical warmup included steady jogging, short sprints, stretching, and explosive drills. The brain tasks were mixed into that routine rather than replacing it, so this was not a case of sitting at a desk and then suddenly racing.
What the tasks did
The cognitive drills were designed to challenge executive function, which is the brain’s control system for switching attention, filtering distractions, and making quick choices. Think of it as the mental traffic controller that keeps everything moving when the body is under pressure.
Some tasks asked runners to switch between identifying colors and shapes. Others required them to pick the correct number while ignoring distractions, or match letters while also deciding whether a number was odd or even.
That kind of mental effort is not the same as scrolling through a phone before a run. It is closer to a short puzzle under time pressure, the sort of task that wakes up attention instead of letting the mind drift.
Faster by a few seconds
The result was clear enough to catch attention. Compared with the physical-only warmup, runners finished the mile about two to three percent faster after adding cognitive tasks.
For a six-and-a-half-minute miler, that kind of improvement could mean roughly eight to twelve seconds. At the neighborhood track, that is not just a statistic. That is the difference between almost getting there and finally seeing the number you wanted.
Professor Christopher Ring, senior author of the study, said the approach “could shave a meaningful amount of time” from an endurance effort. The line lands because runners already know the feeling. Late in a hard mile, the body hurts, but the brain decides whether to hold the pace or ease off.
Not all brain work is equal
The study did not find a clear advantage for the harder cognitive warmup over the easier one. In practical terms, pushing the brain too much before a race may not be necessary, at least for runners like those tested.
That point is important. The finding does not mean athletes should overload themselves with exhausting mental drills right before competition.
Dr. Hannah Mortimer, first author of the study, said the results show that “warming up your brain” can matter in competitive running. Still, she also noted that researchers cannot yet say what the ideal sequence of cognitive activities should be.
Why the mind matters
Anyone who has raced a mile knows it is not only about leg strength. There is noise, breath control, rising discomfort, and the constant temptation to slow down, especially in the final lap.
Cognitive priming may help runners deal with that pressure by making the brain more ready to tolerate effort and stay locked in. Researchers often describe this as reaching a better “flow” state, where pace feels more manageable and attention feels sharper.
That does not make brain priming a magic trick. It is more like tuning an instrument before a performance. The music still depends on training, fitness, and discipline.
Earlier clues from sport
This study fits into a growing line of research on how mental preparation and physical performance overlap. A 2025 Brain Sciences study found that combined cognitive and physical warmups helped reduce the effects of mental fatigue in athletes and older adults.
Other road cycling research has suggested that brain endurance training can improve endurance and cognitive performance after weeks of practice. That work is not identical to a short pre-race warmup, but it points in the same direction. The brain is not just along for the ride.
For the most part, the message is not that athletes should replace physical preparation with brain games. It is that sport performance may depend more on attention, fatigue control, and effort tolerance than many weekend runners assume.
What runners can take from it
For now, the safest takeaway is modest. A short, demanding mental task before a hard run may help some recreational runners feel more prepared and perform better, but researchers still need to test larger groups and different race distances.
A simple button-pressing game or catching balls may sound appealing, but the current evidence is stronger for tasks that demand switching, focus, and quick decisions. So, if runners experiment, they should treat it like any training change and avoid adding stress right before an important race.
Elite athletes may also respond differently. They already use detailed psychological routines, and their margins are tighter. Still, when fractions of a second matter, even a small mental edge can become part of the bigger performance puzzle.
A new kind of warmup
The classic warmup is not going away. Jogging, drills, stretching, and short bursts of speed still prepare the body for the shock of hard running.
But this research suggests the next personal best may come from a more complete routine. Warm the legs, wake the lungs, and give the brain something useful to do before the starting line.
That is a small change with an interesting promise. For runners staring down the clock, it may be worth paying attention to what happens before the first step.
The official study has been published in the European Journal of Sport Science.
