The limit of human potential is something we all underestimate. Six years ago I read the story of Pheidippides who ran from Athens to Sparta (a distance of 153 miles) to seek aid in fighting the invading Persians.
He is said to have run the distance in a day and a half or 36 hours. This run had never been replicated until 1982 when five Royal Air Force officers attempted the course. Three of them completed it, proving it could be done and the following year a competition was born.
Today the course record stands at 20 hours and 25 minutes, but it was the original story that propelled me to take up the sport of ultrarunning myself (since put on hold to focus on my startup). While I haven’t completed a 153 mile race I have competed in numerous 24 hour endurance events and 100km trail runs. Each and every time I believe I have learned something new about myself, as well as the power of perseverance and commitment to a goal or cause.
