Is altitude training worth it for sea-level runners?
i've been thinking a lot about altitude training lately. As a sea-level runner, I'm curious if it's really worth the effort and time for improving my performance. I've read some claims about increased red blood cell production and enhanced endurance, but is it that simple? Are there any runners here who have tried it and felt a noticeable difference? I'm all about pushing my limits, but I'm trying to weigh the benefits against the practicalities of training at higher altitudes. Any insights would be great!
