More About Coach Glenn

First ranked Coachup Triathlon Coach in Colorado, sixth ranked Coachup Triathlon Coach Nationally.

Although my coaching, which began in 1972, generally focuses on endurance athletics (middle & long distance running, triathlon, swimming), I've helped all sort of athletes (football, baseball, soccer, lacrosse, etc.) with their sprint form, leg speed, and mechanics. And since I began coaching with CoachUp in 2012, I've also helped dozens of candidates to the FBI, Secret Service, local or state police, or armed services prepare for and pass fitness tests. Whether you want to cover a short distance fast or a long distance with relaxed efficient form, I can help.

Online Sessions - Discuss current fitness, athletic background, and goals. Devise and monitor training progress with apps (Strava, Training Peaks, Zwift. My online coaching helped a 40-year old female athlete achieve Elite Masters Status with a 3:07 marathon.

Initial Live Consult. Discuss current fitness, athletic background, and goals. Watch athlete warmup and then run a series of short repetitions at relaxed, fast but relaxed and fast (to analyze form, relaxation and mechanics at a range of speeds). Provide fixes, tips and other suggestions to improve form and relaxation. Discuss possible ongoing coaching, online or live.

Weekly Live Sessions (after initial consult). Because good form and relaxation are vital, live sessions continue the focus of the initial session of form and good mechanics. Most athletes meet live at a track once a week, for a series of event appropriate intervals (reps of various lenghts and speeds with rests) after warmup and before a cooldown. We discuss and plan weekly training.

Client Reviews

Response rate was great. Glenn always got back to me quickly with a solution.

I worked with coach Glenn in the fall of 2021 to train for a marathon and I loved the experience. It has been entirely virtual -- communicating by phone, CoachUp, and Strava. Glenn and I talk once a week where we discuss my previous week's runs, what he wants me to focus on for the upcoming week, and insights from his long career both running and teaching others.

In particular, I've found his combination of science based advice with anecdotes about his (and other professional runners) experience particularly engaging and effective for me. And I plan to continue to work with on an ongoing basis.

Coach Glenn was great. He helped my tween soccer goalie learn basic running techniques and gave him some good drills to do on his days off from practice. He also helped him understand the 'why' on the body mechanics of sprinting. He also understood how to get through to my kid based on his age and goals. Further, he worked with our busy schedule as we had to change days and times once or twice.

Coach Glenn gave my son an excellent session today. He provided a science-based overview on running techniques and gave detailed, personalized practical feedback. We are excited to continue with coach Glenn. Highly recommend him for anyone wanting to take up running whether it be for personal growth or as a competitive sport.

Coach is great, but having issues with the app.

Coach Glenn is very knowledgeable and gives importance to imparting that knowledge on you. Keeps it interesting with cool background info on the evolution of running. He’s not intimidating, which is important, and eases you into increasingly better performance. I appreciated the strength training advice for between sessions.

Very knowledgeable.

My son really enjoyed the session with Coach Glenn and received some valuable tips for things to work on to keep improving. Will see him again as needed. Good coach!

My first session with Glenn was great! He is responsive, extremely knowledgeable and detailed, and I really like his approach. I'm looking forward to continuing to train with him.

Coach Glenn is very knowledgeable and has motivated my son to try some new things to improve his track and cross country times and reduce his risk of injury. We are very happy!

Thanks Coach Glenn for a great first session. Your feedback and thoughts on working with Shams show how much you know about the sport and about young athletes. Looking forward to your continued work with Shams.

Coach Glenn is very knowledgeable and experienced. He’s also willing to work around possible scheduling conflicts.

Coach Glenn provided a holistic lesson with insightful feedback on my natural tendencies as a runner:)

Coach Glenn was great. Thorough, thoughtful, and observant. I just needed a couple of pointers to make me run more efficiently before I go to boot camp for the US military. I've already started to implement them and I've already noticed a difference. Thanks Glenn!

Coach Glenn was a great coach. He is focusing on running mechanics and already there is improvement with my son's running style. My 10-year-old son is looking forward to the next scheduled session.

Great coaching! Very helpful! My daughter learned a lot and had lots of fun also.

Lots of great experience, like his temperament, and a sensible approach to training.

Coach Glenn is great to work with. He has lot of knowledge and tips on how to improve my running. During each coaching session I feel a little more confident with what I'm trying to accomplish. He is very easy to work with. I have been traveling recently for work and he had always encouraged me to keep up with my running even if it's just 5 minutes a day. I'm excited to continue to work with Coach Glenn and exceed my goals.

Coach Geln was e celebrate after one session he helped identify areas to improve

He is very knowledgable and I'm looking forward to implementing his strategies to improve my running.

I am enjoying having Coach Glenn as my coach. He is very knowledgeable about running and takes the time to explain the mechanics of running. My foot injury has improved a great deal since working with Coach Glenn while applying his instructions on how to care for the injury. I am being pushed beyond where I thought I could possibly go with regards to running. He has helped me to rethink my limits.

I've been working with Glenn for a couple of months as I prepare for an upcoming marathon. He created a great schedule that has helped me stay focused towards my running goals. He keeps me focused and on task! He is also very positive and is helping me realize that I have more potential than I thought :)

Glenn will be a good fit for me. He listened to what I was trying to accomplish, had immediate suggestions which we tested out. He sees the big picture - but didn't overwhelm me with all he sees. He is prioritizing and building a foundation bit by bit so that we can gradually accomplish my goals. He has good technical knowledge about my needs - but also understands the training process, so that I can absorb the technical skills within a multi-month training program. Glenn's a star

I've really enjoyed working with Glenn, who had gotten me out of my running rut. After decades of running, I never felt like I was actually improving. With workouts based on heart rate, which alternate between track intervals, hill running, and weekly long runs, I'm feeling a lot better now after each workout.

My son was looking for a coach so he could pass his police academy fitness run. Although a pretty good athlete who exhibited skills in short distance (sprints) he was challenged by longer distances. A must to move on in the academy. Coach Glen provided both a method (heart rate monitoring) and confidence for him to pass the first trial. Over a number of weeks at a local track Coach Glen, with a plan based on years of running experience, made it happen. Not sure what he would have done without his help.

I did not run track or cross country in high school, so I knew little when I decided to make running my preferred sport. Glenn patiently guided me to increase the duration of my runs, build stamina, and build speed in part by teaching me to focus on my heart rate when I run. In the beginning, I met Glenn on the trails for longer runs; now, I enjoy meeting Glenn at the track.

My weekly runs have become a pleasure rather than a chore, and I credit Glenn for this. In the beginning of our training, he insisted I run slowly - painfully slowly - to build endurance rather than speed. Over time, I more than doubled the number of miles I run a week. As our sessions progressed, he added speed training, and I now I run faster than I have in years.

All of this after undergoing major heart surgery (me, not Glenn). Five stars!

Coach Glenn has been an awesome running coach and I love the method he uses for training to avoid injury based on heart rate pulses. It makes so much sense and I've been able to ease back into running. I look forward to our morning sessions because his principles and tactfully sound and his bedside manner is extremely agreeable and relaxed. Five enthusiastic stars.

Coach Glenn is great ! He sure knows what he is doing. Very knowledgeable and knows how to utilize that knowledge. I am finishing my third week and can already see the results. I have already exceeded my running distance by 100% without feeling tired or dizzy. Thanks Glenn.

Glenn is very responsive to my e-mails and seems to be very knowledgeable about the sport. He has given me a plan which I have been sticking too and I like a lot so far.

Coach Glenn and I are just getting started but I am already encouraged by his enthusiasm and dedication to helping me reach my goals. His knowledge not only comes from a thorough understanding of the running world but also from personal experience. He has a wealth of information to share and has already taught me much I didn't know about training. I have already booked him for an additional month! I would definitely recommend Coach Glenn based on the experience I've had thus far.
