I am selling this king size Colorado Altitude Training tent (CAT-430 Walk-in Tent System). Its in excellent condition, no defects or flaws. Hypoxic altitude environment up to 12,000 feet. Research suggests that there is between a 3-5% improvement in Vo2-Max by sleeping in this tent. I dropped my Ironman time from 11hrs 15min to 10hrs 33min!

Here’s an experiment in thought: what do you think happens when you look at the reported sleep patterns of a high-powered CEO versus that of an elite athlete? An intriguing dichotomy emerges.
