What people think about the online course (sent via email, Instagram, etc.)

"Fantastic running course. Fredrik is an excellent teacher with a unique approach. I highly recommend this course to runners of all levels."

"The best money I have ever spent. Great mix of humour, practical technique and theory. It’s brilliant and I have been telling all my friends about it. I’ve knocked 30 secs off my average pace to 4:30 and at 53 I’m absolutely astonished how relaxed I feel running. It’s also really helped my cycling my adapting similar techniques and visualisation . Thanks so much.

”The content of this course is really nothing less than amazing” 

”Today I ran I with audio lesson no. 2 from your online course. Increased the pace from 6:30 to 5:30/km (10.27 to 8.50/mile) without it feeling harder. On the contrary actually.”
Runner writing an email on how the course is going 

"I was really skeptical about the online course. Thought it couldn't possibly work if you don't see me. But then it was like magic. Like you saw me and saw exactly what I was doing and what happened when I followed the instructions."

I can honestly say it is some of the clearest and best instruction I have ever recieved in any topic. After a year of shin splints I went for a run yesterday and was almost in (joyful) tears because I had zero pain, so thank you!!

”I got your online course and it almost instantly fixed my running form. I can prove that by having half an hour faster marathon finishing time.”
Runner, Indonesia

"There are two types of runners; those who have taken Fredrik’s course and those that should!"

"Fredrik is a pedagogical GENIUS and posses deep knowledge and experience within running more effectively and injury free. For PROS as well as amateurs."

”Finally, explanation of running technique corrections that make sense and can be explained using physics. The clear and humorous way Fredrik presents the topics make them stick. Great course!"
Running and Triathlon Coach, The Netherlands

”The instructions was clear and enjoyable - you are an excellent teacher. Last week I ran my second marathon, the Chicago Marathon, with a time that qualified me for Boston (and ran 30 minutes faster than I did in my first marathon more than a decade ago). the running technique I learned from you played a huge part in my performance improvement. I couldn’t have done it without you. Thank you very much” 

"Thank you for your running course - it’s fantastic"
Runner sends message about the online course via Instagram

”The course is fantastic! Fun, developing and Fredrik is an educator from another planet!”
Runner contact me spontaneously to thank me for the course

”Thank you for your awesome online course on running technique. Very educational and useful, above all simple tools to work with. Both for myself as a runner and, above all, in running technique analyzes of my clients/patients!!”
Osteopath and runner

"Incredibly good. Educational, concrete, funny. Recommended!" 
Satisfied runner 

”Very rewarding. Many "aha moments". And what a good timing you have in your comments in the audio lessons, it was as if you were right next to me. I can say that there is a BIG difference between before and after the lesson. I will recommend your course to all runners I know!”

Mail from a runner after the first of the six audio lessons

"I can really recommend the course. Small simple tricks that make a big difference"
Runners comment on the course on Instagram

”I have struggled with an ITB syndrome for several years. Went to many physiotherapists, had online personal trainers, ran on gravel roads, paths, asphalt and tested different shoes. Nothing has helped. Did rehab with all sorts of different exercises and most recently I was told that it is probably surgery that applies to make me run without pain again. Bought your online course and thought it would probably be the same result as with everything else I have tried over the years. BUT now I almost always run without pain. Ran 7 kilometer (4,35 miles) last week without pain. Thank you, Thank you, Thank you for this course. Never thought an online course could be this good. Now I start again in lesson no. 1. A joy to run with you in my ears.”
Runner in a thank you email

”I have done the first two audio lessons now. It's amazing what a difference you made for me. I ran 90 minutes yesterday and have never felt so refreshed both during and after the workout, and then I have never run so fast with the same low heart rate. Thanks for that!!”
Update from a runner after two of the six audio lessons

”Today I tied everything together and I felt "What the hell !? How is this possible?". I am convinced that you have been an apprentice to a witch doctor in deepest Africa. There is no other reasonable explanation, because it can be impossible that if you tie everything together, the whole running technique changes completely. Only black magic can solve that. I immediately felt that my lower legs no longer felt sore. I also wanted to run more. In the past, I have reluctantly done so solely out of sheer stubbornness.”
The idea of the course is that everything should feel like a single movement that comes by itself. Not a hundred things to keep track of. Something this runner discovered and also found that his Garmin watch announces sudden performance improvements

”Thank you for a pedagogical, effective and (this should not be underestimated) fun course.”

”I have done the first part of the online course and been out running with the first audio lesson with Zillén in my headphones. Incredible feeling. All of a sudden I found a gear I did not know I had. As if a turbo was turned on. And I have probably never or rarely come across such pedagogical instructions. Even though I have worked as a teacher for 25 years (Teacher educator, take lessons). How easy to follow. I was honestly also a bit skeptical before but all those prejudices came to shame right away. In addition, Fredrik is f ***** g funny, as the icing on the cake.”
Online course participants in a comment on Instagram

”I must admit that I was quite hesitant about how effective an online course could be. But I have learned a lot. Without being in as good shape as before, I managed to touch my PB of 10 kilometers. A real difference to run in less than 40 minutes with this running technique.”
Satisfied runner 

"Tonight I did audio lesson 2 from your online course. There are so many "aha moments" so far. My "usual" running stride feels like I'm sitting heavily in an armchair, now after what I learned from you, I feel like I'm flying forward." 
Online course participants in a comment on Instagram

“I have now come to the first audio lesson. I just have to say that it is extremely exciting and clear how the whole course is structured. Very entertaining and everything feels so obvious. Looking forward to going on a new run tonight with you in my headphones!"
Message on Instagram 

”An equally informative and pedagogically structured course is hardly available. And it’s fun."
Online course participant

"I'm halfway through the course and have to write and thank you for the results I got. I have previously been unbalanced with 47% - 53% in ground contact time and always wondered how to overcome this which generated in running injuries on one side of my body. After following your instructions this has changed significantly. Now the average is 49% - 51%. Last session which was a bit harder, 12 km, I was at about 50-50% the first 6 km and only then the margin of error started to come. I just want to say thank you. It will be really fun to continue the course.  You are awesome."

Runner after a running technique analysis

"Coming in rested after a 16.5 km run felt strange. I ran 20 sec/km faster on average at exactly the same heart rate as usual in my long runs. Forever grateful!" Alberto, less than a day after a group course

“We did not focus so much on getting faster, but more on getting free from my ITB syndrome. I have been suffering from the injury for about 4 years. It was strange, but amazing that I ran painlessly!”
A runner who after four years of pain ran with a smile a marathon completely without knee pain two weeks after a meeting with Fredrik Zillén

"Clearly faster then, also with a couple of beats lower in heart rate."
Runners who after a private course compared kilometer times and heart rate with the same distance the week before the course

“A really holy s..h moment t moment /… / I usually run at 162 beats per minute but now I was steady at 157 with some peaks at 158. Such a nice feeling that I increased my speed without my heart rate going up more than 1 beat. There are usually quite a few beats for me otherwise.”
Runner after a running technique analysis

“Insanely inspiring visit to @fredrikzillen this morning. With a clear pedagogy and a brilliant eye for detail, he gave me the keys to a more efficient and relaxed running technique. You can almost believe that he is doing witchcraft.”

Runner the week after a private course

"Another unreal, rewarding and inspiring meeting with the running magician @fredrikzillen"
Runners after a running technique analysis

“After the course, I ran and had a 30 sec lower average pace compared to a session on the same distance I ran a few weeks earlier. At the same time, my Garmin showed that the "training effect" dropped from 4.2 to 3.7. I thus seem to have run faster but made less effort”.
Fredrik J, after a small group engineering course

"When I run as usual, I have pain in my knee. When I run the way you want, I feel no pain at all. It's absolutely magical”. 
64-year-old triathlete whose doctor completely ruled out his chances of running again due to pain from osteoarthritis

“1. I have been able to double (literally) running distance / month without any problems. 2. On average, the heart rate has dropped remarkably. 3. I have no pain in my shins, knees or Achilles tendon, like I have had before.”
