Lactate threshold myths for serious runners: what actually moves race pace

RC
By Ramon Curto · MSc Exercise Physiology · 15 years coaching

Cut through common threshold-training myths with a practical framework based on Garmin + Strava trends, not guesswork.

Threshold work is one of the highest-leverage tools in endurance training. It is also one of the most misunderstood.

Myth one: threshold means 'as hard as possible.' In practice, threshold should feel controlled and repeatable. If you are fading badly by rep three, intensity is too high for adaptation quality.

Myth two: more threshold is always better. Serious athletes usually improve faster with one focused threshold session plus strong aerobic support, then weekly adjustments from Garmin recovery and Strava load trends.

Myth three: one bad session means no progress. Look at 10-14 day trends in pace stability, heart-rate drift, and recovery. At SportPlan, we coach threshold as a precision tool that builds race pace over months, not a hero workout for one day.
