Unlocking a Sub-

In this video, Kevin analyses the physiological data of a runner aiming to break 3:30 at the London Marathon next year. The runner wants to identify potential performance limiters and determine which aspects of their training should be prioritised during the winter months to avoid "hitting the wall" on race day and give them the best chance of success.
We examine a variety of key data points, including VO2 max, aerobic and anaerobic thresholds, running economy, and fuelling strategies. Based on this analysis, we highlight the critical areas the runner should focus on to successfully reach their target time.
