Who We Are

We’re a group of adventure seekers and sports fanatics dedicated to making the highest quality altitude equipment and providing the very best service in this niche industry. Founded in 2015, Mile High Training was founded on the belief that we could provide superior equipment and vastly better customer service at a lower price point than our competitors. We feel both fortunate and proud to work with pro athletes, research facilities, business owners and all around interesting people doing amazing things. Our team has over 60 years combined experience in sports technology and athletic strength and conditioning and we’d love to put our experience to use for you. 


Return Policy

We offer a full 30-day no questions asked return policy for all personal-use equipment purchased (not rented) from Mile High Training, excluding the mask, which cannot be returned for sanitary reasons. There is no re-stocking fee for returns, though we will ask that you cover the return shipping if you decide to return. If you receive a broken or defective product, we will replace it at not cost and provide the shipping label at no charge to return the defective equipment.


We also offer an industry-leading 2-year parts and labor warranty for all purchased equipment. Our Commercial-grade High-Flow equipment does not come with a return policy (each system is custom built) but we do offer an industry leading 3-year warranty on all commercial systems. We strive to deliver absolutely amazing customer service – from discussing training programs and protocols to working with directly with contractors – and we hope our no questions asked return policy provides you the confidence to be able to move forward with owning your own high altitude training system.

Altitude Training Mask for Basketball Players

“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

Altitude Training for Kilimanjaro
“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!”
Altitude Tent to acclimate to altitude

“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.”
Jon G. – Boston, MA


“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!

Altitude Tent for Kilimanjaro

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!
