A solid metric to know, considering its influence on race performance. Many coaches argue that lactate threshold is one of, if not the, biggest performance predictor. It determines how fast you can ...

We sat down with HYROX master coach Tiago Lousa to break down the real method to race-day speed, the mistakes holding athletes back and the fixes that make you faster without blowing up. Whether ...

One of the best measures of running fitness is lactate threshold (LT), which is the running speed or heart rate at which lactate — an intermediate product of aerobic metabolism in the muscles — begins ...

Polarized training is based on a clear 80/20 distribution: 80% of your training at low intensity (max HR 65–75%) and 20% intense (at or above the anaerobic threshold), while the middle zone is largely ...

If you’ve read even a small amount of running research, you’ll likely have come across the term ‘lactate threshold’. But what does it actually mean? In essence, your lactate threshold is the point at ...

After the USA Track and Field Championships in August, Emily Infeld – who won the national title in the women’s 10,000 meters – told reporters she incorporated double thresholds into her training once ...
