Robotic Environmental Simulations for Endurance Training

I work in health insurance, so I see a lot of data on performance and injury prevention. It got me curious about the tech side of training. I’ve been reading about robotic systems that can simulate altitude, heat, humidity, or even cold for athletes. For endurance folks training for events like ultra-marathons or high-altitude climbs, this seems like it could offer a controlled way to adapt to race-day conditions without having to travel. But I wonder how practical it really is. Has anyone here tried training with that kind of tech, or know athletes who have? I’m interested in whether the physiological benefits are significant enough to justify the setup, and if there are any downsides like does it feel too artificial to be useful? Would love to hear some real-world experiences or insights.
