Whats the real benefit of using intervals to improve lactate tolerance when most gravel and mountain bike courses dont even allow for consistent, uninterrupted efforts? Is the traditional interval approach - 4-6x8 minutes at threshold, 10-15 minutes rest - really the best way to build lactate tolerance for the varied, unpredictable terrain and pace of off-road racing?
Does the average off-road cyclist really need to worry about lactate tolerance in the same way a roadie does, or are there other, more relevant physiological adaptations that should be prioritized? And what about the role of anaerobic capacity - isnt that more important for the short, explosive efforts required in off-road racing?
How do you reconcile the need for lactate tolerance with the fact that most off-road courses feature extended periods of low-intensity riding, followed by short bursts of high-intensity effort? Shouldnt interval training be more focused on building anaerobic capacity and muscular endurance, rather than lactate tolerance?
And what about the impact of fatigue on lactate tolerance - doesnt the cumulative fatigue of a long off-road ride or race negate any benefits gained from interval training? Shouldnt we be focusing on building resilience and endurance, rather than trying to optimize lactate tolerance?
