Client Testimonials

I’m back and we summited! Weather was terrible with howling winds and sleet, but we were climbing during the wrong time of the year. Supposedly, June – August is way better weather-wise. Honestly, with the weather and altitude, there is no way we could have made it without your altitude tent. Only 7 people summited that day and the other 5 were “professional climbers”. That was about a 15% success rate whereas they have more like 50-60% in the dry season. Pierson and I were the only 2 people in our group to summit and we had some pretty impressive people in our group including an Olympic skier from Brazil. Thanks Mile High!

Our training staff put together one of the best rehab programs I’ve seen, doing simulated game conditioning, high-altitude training and all this crazy stuff,” Griffin said. “I’m actually recovering at a better rate now than I was heading into the season.

Blake Griffin – NBA All-Star

It was a great trip and to be honest my cousin and were amongst the best when it came to altitude issues. We did both take Diamox as well, but as did many others, the clear difference was our high altitude training prior to arrival. Given that we both live at sea level we performed surprisingly well. Both had solid blood oxygen and pulse stats all trip long.

“We did it! My team and I concluded a very successful summit of Mt. Kilimanjaro and are ecstatic to have raised so much for our charity, The Rich Center for Autism. Our 3 team members that used your equipment all faired far better than the rest of the group. While four or five others experienced significant headaches and fatigue, the three of us never dealt with the light-headedness or nausea we were all expecting. We’re very thankful we got to enjoy our summit day altitude sickness-free!

David R. – Youngstown, OH

“When I decided to rent with your company, I considered all possible options and I concluded that Mile High would provide the highest level of service and best preparation for my trek to Kilimanjaro. This trip was a lifelong dream for my daughter and I, so we took every step we could to make sure we would succeed. We summited February 2nd, 2019 at 9:14 in the morning and it was truly a memory we will never forget. Considering we had no altitude issues while much of the group did, I’m very happy I made the investment to ensure altitude wouldn’t be something that could derail our adventure. Thanks a ton!”
