Really easy. I seem to get the problem where buttons get stuck. To do this just do all the training. Don't have to actually try to just let it go and hit space when it is done. Do this for all training to 150, spend the gold you get on the cheap seed and then spend it on energy to max. When that is done all the races are easy to win.
