I have full faith in the program after seeing my results in 6 weeks ... After just 6 weeks. I had a great improvement on my Power by 40watts! And a 4:30min improvement on my run. Over the past 6 weeks I have really tried hard to stick to the training program, it hasn't been easy! But I can honestly say that I have full faith in the program after seeing my results it's really pleasing to see such great improvement Thanks
