Whats the real benefit of Zone 2 training for cycling efficiency, or is it just another buzzword thrown around by coaches and training programs. Does anyone actually have concrete evidence that spending hours upon hours in Zone 2 leads to significant improvements in efficiency, or are we just assuming it does because its been repeated ad nauseam.
Ive seen countless training plans that include Zone 2 work, but Ive yet to see any real-world data that supports its effectiveness. Are we just wasting our time with this type of training, or is there actual science behind it.
Furthermore, how does Zone 2 training impact different types of cyclists. Does it have the same benefits for sprinters, climbers, and endurance riders, or are there different types of training that are more beneficial for each discipline.
Im not looking for anecdotal evidence or hearsay, I want to see actual data and research that supports the effectiveness of Zone 2 training. If its just a myth, then lets stop wasting our time and focus on more effective training methods.
