Spartan

Spartan organises obstacle-course races and training events, ranging from short Sprint events to longer Ultra distances. Its official story says Joe De Sena founded Spartan in Vermont in 2010 after organising the Death Race on his farm. Spartan presents its races as a way to test endurance and resilience and says the events have spread across more than 30 countries; those scale and personal-growth descriptions are its own claims, not a promise that any participant will achieve a particular result.
