Recovering from an IronMan competition can be a challenge by itself but for Chronic Fatigue Syndrome (CFS) patients the real challenge is every day life. The consequences of participating in one of the most physically demanding races are very similar to the symptoms that CFS patients experiment. This illness affects up to 3% of the population. With this idea in mind, 8 participants from the IronMan race in Barcelona have started the #IMHeart project. Using a Smartphone app kilometers will be accumulated whenever the users are exercising, later those kilometers generated will be ‘donated’ to CFS research projects. The kilometers covered will be given to the study coordinated by Dr. Jesús Castro, from the "http://www.vhir.org/larecerca/grupsrecerca/ca_grups_equip.asp?Idioma=en&mv1=2&mv2=1&mh1=2&mh2=1&mh3=1&mh4=0&ms=0&area=7&grup=6&menu=3" Chronic Fatigue group at VHIR, headed by Dr. José Alegre, titled “CFS and fibromyalgia in teens: emergent entities that determine academic failure and deterioration of life quality”. The project is drove in collaboration with several national and international research and university centers such as Hospital Sant Joan de Déu, Centro Médico Delfos, Hospital Clínic and University of Bristol (UK). The ‘Associació Catalana d’Afectats de Fibromialgia, SFC I SQM’ ( "http://www.fibromialgia-cat.org/cat/frames.htm" ACAF) also gives support to the cause. For participating in the donation it is necessary to get registered in the web: "http://app.iwopi.org/login" http://app.iwopi.org/login, and download the Runkeeper app for Smartphone. Once some distance is covered, you can donate the kilometers through the iWOPI web to the CFS project.Through the "http://www.iwopi.org/" iWOPI platform, the kilometers given by the donors will be accumulated. The challenge thrown is to achieve 150.000 km in three months. Those kilometers (or miles) can be earned either running, walking, swimming or riding a bike. The ultimate objective is to be on the move for those who cannot do it every day.
