Thanks so much Pedro for that encouragement and advice! I 100% agree! Actually I was not very clear before, but I was asking for advice on eventually doing an ultramarathon. My dream would be to do a 100 miler – without getting too badly injured in the process. I was curious what your thoughts were on how long it would take me to train for that, considering I am only now starting to train for a marathon. I would want to work my way upto a 50, 75 and maybe a 100? And was curious what your advice would be on how long it would take me and whether its even feasible.
