GO² brand ambassadors
MULTIPLE IRONMAN/70.3 CHAMPION
"I recently started using the GO² device and felt it provided me not only a physical benefit with increased oxygen, but it also helped mentally, helping me keep my breathing steady while running."
“As soon as I saw the GO² Device I understood the science behind it and recognized the performance benefits. I've experienced a notable performance increase in training - particularly at high altitude - and look forward to extreme-testing GO² on my upcoming K2 winter expedition in Dec 2019.”
“When using the GO2 device I focus so much more on my breathing and less on how difficult the run is. I notice my pace has increased dramatically since I started using it and my heart rate has decreased.”
Avid Runner & Hiker
"Throughout my entire marathon training process I found the device incredibly useful, especially on longer runs. Using it for a mile or two, in intervals, provided extra energy and made "proper" breathing easier even when it wasn't being used."
