After the ride, I ran without any distance targeted in mind. I just ran and reach the U-turn point and striding to the finish. As a post running section, I had a quadriceps pull- the feeling that I'm missed so much- only to have that during race time. Perhaps, this coming Sunday I will not feel that muscle pull. The reason it happen was easy to know - I'm dehydrated, 500ml of plain water for entire workout under mid-day sunshine.
So, I'm ready to race this Sunday as to be a finisher of 'The Slowest Powerman Finisher' since 2003.
