Lactate Threshold Power (LTP) is the highest power output you can maintain for a sustained period without lactate building up too quickly in your blood.
It marks the intensity where your body shifts from mostly aerobic effort to a point where lactate begins to accumulate faster than it can be cleared.
This threshold is often used to set power training zones and plan workouts more effectively.
Riding just below your LTP helps build endurance, while training at or slightly above it improves your ability to handle higher intensities.
Most cyclists estimate LTP using a field test, like a 20-minute effort, and adjust their training zones based on the result.
Knowing your LTP allows you to train smarter by targeting the right intensities for your fitness level.
It’s a key metric in structured training plans, especially when working to increase sustained power and delay fatigue during longer efforts.
