For the last completed Marathon, I invested more than 50 hours training, completing 650 Km to reach the goal of setting a sub 3h time in marathon. I succeeded!! This is why I want repeat it, but with an extra motivation. It's nice to know that my effort can help others...So you can help me now!! Will you? The challenge is to achieve 1€ per Km on my way to complete my 10th marathon in Valencia next December 2nd.
