I am getting better with each race, I run more relaxed as well. I feel confident. I know that all I need to do is to trust my coach and to trust myself. The coach knows what is best for me. I really love this Monaco crowd and the introduction of the event with the lights. I will get back to practice and just focus for my preparations for Paris."
