Are there any adjustments that need to be made as someone who is training inside urban area, with no convenient high altitude access?
Can the zone/heart rate method that is used by most of the athletes on here be useful to increase my aerobic endurance; since there is no steep terrain, only some slight hills? Or is simply training by time enough?
Since being in a detrained state, I’m seeking ways to enhance my training thought process based on what little terrain I can access.
