My training philosophies is that change is good, change forces adaptation and improvement. If you want to be the same rider that you have always been, train the same way you always have.
I suggest using a power meter as it enables you to train much more specifically and gives you the confidence that you are training at the right intensity. At the same time it provides you with concrete evidence of your improvements. That can translate into going faster on the bike and achieving your goals.
If you are ready to change it up, work hard, and open your mind to new possibilities, I can help you achieve your goals.
