Lactate Threshold Pace Calculator
Estimate your lactate threshold pace from a recent race result, typically 85-90% of 5K race pace for trained runners.
Lactate Threshold Pace
5.00 min/km
Lactate Threshold Pace vs 5K Race Time
Lactate Threshold Pace
The lactate threshold (LT) is the exercise intensity at which lactate begins to accumulate in the blood faster than it can be cleared. Training at LT pace improves endurance performance.
Estimation Method
LT Pace = 5K Race Pace / Threshold Percentage
For well-trained runners, LT pace is approximately 88% of 5K pace (or about 15 seconds per mile slower than 5K pace). This corresponds roughly to the pace you could sustain for 60 minutes in a race.
Example Calculation
A runner with a 22-minute 5K using 88% threshold estimate.
- 015K race pace = 22 / 5 = 4.40 min/km
- 02LT pace = 4.40 / 0.88 = 5.00 min/km
- 03LT pace per mile = 5.00 x 1.609 = 8.05 min/mile
