Long-term fitness growth relies on aerobic development, and focused base periods are an opportunity to lay the groundwork for breakthroughs. This 12-week plan builds training volume while developing top-end speed. Breakthroughs await.
Training theory: output at VO2 max while climbing may have a high predictive value for athlete progression and regression over time, particularly with age. Constant reinforcement of this metric may improve performance at all effort levels, including long ultras, and can seem to reverse the athletic decline process in some cases.
Three science-backed tips for creating a training system that supports long-range athletic goals and progress.
