Mile High CrossFit®: Opinions

Fantastic experience: I love this gym! Great atmosphere, awesome coaches. You really get fit!
Fantastic experience: Great Gym! I have been involved in Crossfit for several years now and can honestly say that the owners and staff here really know what they are doing, and care deeply. Lot's of room. Large variability in experience from beginners to highly skilled. Kids, dogs. Feels like family!
Fantastic experience: From the moment you walk into the door, you’ll feel welcomed and supported. The staff up front are always helpful and kind.
Fantastic experience: Dropped in for three days while in town for business. Great programming and coaching, members were very welcoming. Troy (the owner) was great, responded to emails immediately and runs a great box. I will definitely return on my next trip to Denver.
Fantastic experience: Great place to drop in to. Everyone made me feel at home there, and Troy was an awesome host! I highly recommend this gym. Great experience!
Fantastic experience: I joined MHCF in October of 2019. I was a former collegiate athlete desperate to find a gym and group of people I could relate to. I met Coach Kris on Labor Day during one of the workouts. Everyone was working hard and encouraging each other even though the workout was absolutely brutal. I knew after that initial visit, this was the place for me. Kris is thorough in his coaching and takes time to actually teach technique. He holds everyone accountable to maintaining that technique during every workout. Not only that, Kris runs the cleanest gym around. Even before the pandemic, the MHCF facilities were always clean and well maintained. It has never smelled like a gym! Kris and the rest of the coaching staff work hard to create a great learning environment for each and every person who comes to class. The people that make up MHCF are inclusive and family-oriented and will push you to be your best. I have met some of my closest friends at MHCF. If you are in the Denver area and looking for a clean gym with a supportive, welcoming community, look no further.
Fantastic experience: Positive: Communication , Professionalism , Quality I found MHCF after moving mid pandemic to a new city where I didn't know anyone. They welcomed me with open arms, focused on athlete safety and facility/equipment cleaniness during the pandemic to keep us all able to workout in a safe environment. Excellent programming and community!
Fantastic experience: Joined MHCF in Dec 2019. Absolutely love the coaches, athletes and the gym. Everyone here is genuine and they push you because they want you to succeed. Gym is clean, organized and sanitized after every workout. Highly recommend if anyone is looking for a place where they can have fun, work hard and become part of the family...join this box!
Fantastic experience: Kris (coach, owner) has build a great community of fitness enthusiasts at MHCF besides being a very professional, knowledgeable, supportive coaches and a great CrossFit gym. We go as a family with 2 kids, and Coaches find a way to encourage us to achieve next goal while making it fun.
Fantastic experience: I’ve been attending MHCF for over a year now. The coaches are great! The members are great! There are all levels of athletes, young to older, crazy strong to just starting their fitness journey. Everyone is encouraging. The gym is located in a modern warehouse so there’s plenty of room and you don’t have a claustrophobic feeling I’ve experienced in strip mall boxes. The owner, Kris, takes pride in his gym and it’s always clean and organized. Equipment it top-notch. The gym is conveniently located off busy streets so running outside is safe. MHCF utilizes a crossfit app so you can see workouts online, record your scores, and schedule a class slot (limited during covid). If I had to sum MHCF up in one word, it’d be, “professional.”
Fantastic experience: I have been a member of MHC for two years. The gym is so clean and organized. The coaches have pushed me psychically! I am the strongest I've ever been in my life. The community here is awesome and truly care for everyone!. Great people and friends!
Fantastic experience: Positive: Quality Great facility and community. Everyone’s friendly and welcomes you with open arms. Kris is great and runs his business like it should be ran. Focusing on safety first
Fantastic experience: Positive: Communication , Professionalism , Quality This box has been our home for almost 4 years now! It is by far the best box we have ever been apart of and love our CrossFit family here! Coach Kris is hands down best owner and has created a very enjoyable community! The coaching programming is top notch! Love MHCF
Fantastic experience: Nice place to get good workout.
Fantastic experience: Dropped in from Chicago and I have as much love for this gym as I do for my own. I’ve been to a few different CF boxes in the area and this is without a doubt the best one. Fantastic coaching staff and programming, the actual facility itself is spotless and extremely organized, members are friendly, and the owner Kris is a really great guy. I’d join this place if I lived here but for now, I’m glad I found it for when I’m visiting.
Fantastic experience: I highly recommend this CrossFit gym. You'll get the care and attention to make sure you're doing the workouts right. And you'll get the gains you want as long as you put in the work.
Fantastic experience: A great atmosphere with amazing coaches. Thanks Mike and Kris for hosting me while dropping in for work. Cant wait to come back and see you guys again.
Fantastic experience: Kris and his team know how to coach and help their athletes. They continually encourage each and every member to be better. Outstanding classes and very well managed.
Fantastic experience: The experience and knowledge of the coaching staff provides a workout of the of the highest caliber. As such, everyone receives a personalized and monitor workout
Fantastic experience: My family has been members of 4 other boxes and MILE HIGH CROSSFIT, is by far the best! Cleanest! Challenging, well rounded, and best programming we’ve experienced. The owner is very knowledgeable ,articulate and knows just how to guide you, push, teach and coach you! The equipment is vast, top of the line and allows for a great variety of workouts........ and the best part, this is truly a DRAMA FREE box- The Horsfall family
Fantastic experience: The experience and knowledge of the coachin staff provides a workout of the of the highest caliber. As such, everyone receives a personalized and monitor workout which why this box has a large number of people who have been members for years.
Fantastic experience: Moved here from WA 3 months ago and was on the hunt for a gym that fit me. Didn’t have the best results from globo gyms so I was down to try something different. Had MHCF recommended by coworkers and it was one of the best moves I’ve made since moving to Colorado. The family vibes and supportive environment are impossible to beat. Couldn’t imagine being anywhere else!
Fantastic experience: I have been to a lot of Crossfit gyms all over the country and MHCF is a great one. Great coaches, great "super clean" facilities and great community. I appreciate the motivation to go harder, do more and push myself to do better. It actually carries over outside the gym too. Thanks!
Fantastic experience: Can't to get a workout there
Fantastic experience: The best!!
Fantastic experience: Great coaches and a clean, aesthetically pleasing environment make this a great cf gym. The warm-up is generally pretty dynamic, and the coaches have a great, safe balance of pushing you to work harder without sacrificing form and posture.
Fantastic experience: I dropped in to Mile High CF this morning and had a great experience. The facility was well organized and clean and the people were very friendly. The coach took the class through a good warmup, clearly explained the WOD, and provided ongoing input and monitoring throughout the class. Excellent gym!
Fantastic experience: Dropped in while in town for work. Got this cool shirt and a great workout too!
Fantastic experience: Was looking for a new box a few months ago and stumbled on this place. The trainers/owners Bekka and Kris are great instructors and really make sure you learn things the "right" way. I love the group warm up and the workouts are always challenging and fun. If you are looking for a box that is low stress, friendly atmosphere, and no egos go check it out! Also great selection of equipment and ALWAYS a clean gym!
Fantastic experience: Best cross fit coaches, small class and every one support each other to get better in shape, clean facility, variety of workout everyday.
Fantastic experience: If you want a gym with a highly knowledgeable staff that are also friendly, this is the gym for you! I have been attending mile high crossfit for about a year now and could not be happier. From the first class I have been pushed to my limits and broken them. The coaches work hard to help you achieve your goal. I even plan to move soon and will make over a 30 minute drive one way to attend this gym. It is truly that worth it!
Fantastic experience: Great trainers and great variety. I do something new almost every time I come in so I'm always learning and getting better every workout. Highly recommend to anyone looking to improve their fitness level.
Fantastic experience: This was my first Crossfit experience. When I started back in August of 2015, I really didn't know what I was getting into. The team of coaches, including my personal coach Kris, has made this one of the most fulfilling and positive experiences of my life. Crossfit has been physically and mentally demanding. Everyone here at MileHighCrossfit has been fantastic. They are a great group. Come join us!!! You will LOVE the experience.
Fantastic experience: MHCF is a great place, regardless of your fitness level - everyone is welcome and made to feel at home. I've been working out with Bekka and Kris (coaches & owners) for almost 5 years now - and I'm stronger and fitter than I've ever been, all thanks to them. They have coached me to do things that I didn't think were possible, which keeps me coming back for more. Lots of focus on technique - they are very good at breaking down the movements so that I can get them right. Good variety in the WODs too - it's always interesting! I wouldn't want to go anywhere else.
Fantastic experience: This is an awesome Box! I had been working out for a few years at non-CrossFit gym that focused on HIIT and I thought was strong and in decent shape. After joining Mile High CrossFit, I soon realized I was not as strong as I thought. I needed to focus on technique and the coaches at Mile High CrossFit were there to help me get my technique down before I focused on increasing weight. The coaches also focus on mobility and I have learned the importance of being mobile and how mobility increases strength. I have been a member of Mile High CrossFit for a year and have improved immensely I only wished I had stared my Mile-High CrossFit journey years ago.
Fantastic experience: This is by far the best gym I have ever been a part of. The coaches are incredible. They really help you reach your personal goals and they are very nice and easy to talk to. On top of that they are really knowledgeable about different forms, warm-ups, and CrossFit all together. The gym has a lot of good equipment which means that the workouts are diverse. The WODs are challenging but 100% worth it. The workouts are great for everyone, from beginners to the more experienced crossfitters. I would HIGHLY recommend this place to anyone who is serious about getting into a great workout routine. Since I have been at MHCF I am much stronger and I have learned many new skill sets. I also have a lot more energy and the coaches have given me great resources that help me eat better. My overall health has greatly improved. There is no other gym that comes close to Mile High CrossFit!
Fantastic experience: Mile High Crossfit is by far one of the best Crossfit boxes in Denver. I recently moved to the area and the coaches and members instantly made me feel like family. A great atmosphere to enjoy getting your ass kicked
Fantastic experience: The biggest strength of this gym is the coaching, which is everything in crossfit really. The coaches really care about form, while pushing you to your limit safely. They want you to become the best you can be, but without injuries. They always walk around during skill/strength training and wods and offers great support and tips for improvement. They have a good, diversified programming. Although I wish them the greatest success, I do enjoy the small classes and the more personal coaching. With regards to crossfit boxes, this is probably the best kept secret in town!
Fantastic experience: Great box!! The coaches are very knowledgable and do a great job helping with technique and making it a fun atmosphere. Good programming, too. I'd reccomend MHCF to anyone from a first-timer to a seasoned crossfitter. Big fan of MHCF!
Fantastic experience: I have been coming to MHCF for a year and I love it. Kri$, Bekka and Rob are all excellent coaches. Great group of regulars, too. If you are looking for a good gym in the Centennial area this is the one.
