Apparently, because polar ice is melting the earth rotation is changing and we're going to lose a second.
How to adapt your training if the earth rotation is changing ?
And does it means that if you run a 4:00 mile in the future, it will be equivalent to a 3:59 mile today ?

Nope
It means every runners in the world will have to run in the opposite direction of the rotation of the earth in order to inverse the process.
So you’re telling we can add an additional conversion to Jim Ryun? He’s gotta be at least a 3:21 1500 now
Your mile time will be faster than expected only if the negative leap second is applied while you're running your mile AND a clock (rather than a stopwatch) is being used to time you. For example, if it's being applied at midnight and you start your run at 11:58:00 and finish it at 12:02:00, 4:01 will have passed but you'll have finished 4:00 after you started.
A better plan for using this strategy is to run a half marathon at the end of Daylight Saving Time. Start your run at 1:55am, run 13.1 miles in 75 minutes, finish at 2:10am...World Record, baby.

Does not sound right
The Earth rotation is not changing, the universe rate of revolving around the Earth is changing.
For runners? Nothing, time is defined atomically now.
"The second is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium-133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s−1."

and what if those atoms speed up or slow down, and you don't notice? If they all do it at once, you have no way of knowing.

It isn’t changing by one second every 4 minutes.
It's not the super shoes; it's the earth's rotation that's making us faster.
