Are LT1 sessions the key to running a faster marathon? 🤔
You might be wondering what LT1 is?
LT1 is the first lactate turn point, which simply is the point where lactic starts to noticeably rise in your blood. Essentially when you are running faster than easy pace and is “steady” running
“But isn’t lactate bad for you?”🙄
No! Lactate is used as a source of energy… where it becomes “bad” is when you produce it faster than your body can clear it, which is where you go beyond LT2 and what people understand “threshold” to be
These sessions have been implemented over the past few months and they have seen the same effort level/heart rate result in a pace improvement of 17 seconds per mile for James! 🤯
Are LT1 sessions the missing piece to your next marathon PB?
