challenge, sadness, stress, pain, forget and ignore it, think positive, do not give up, keep the physical and mental strength. if it is not capable of running can keep pace with walking, do
not rest too long unless he's able to move forward with speed, should make thorough preparation, do not forget the mandatory item. it is ultra running, let us move slowly as long as get to
the finishing line.
my message to all fellow runners do not make it as a reason of failure, so we do not dare to try and keep up the fight in ultra running.
