Here I am with my triathlon coach Aleksandar Sørensen-Markovic in Samsø Denmark relaxing after training. He is great coach and mentor and we share many of the same methods in terms of coaching protocols and values in terms of relationships.
There and many benefits of having a coach or mentor and even with my experience and knowledge I find I need a helping hand and someone with objectivity who has an understanding of how it feels.
A coach will give training protocols, teach you how to carry out the training and eventually go away and do it on your own. A mentor will tell about training but will also tell you how it feels on the start line of your first Ironman, what to pack in your transition bag and be able to understand the highs and lows you will go through.
