The sartorius muscle starts at the outside of your thigh and with a graceful s curve ends up on the inside of your knee.
according to Livestrong foundation, strains and sprains of sartorius muscles are often found in runners and skiers.
So how did I hurt mine? any other cyclists ever do that? It's healing well but it was the strangest thing, i could trace the whole muscle out for the first time in my life because it was so ouchy..
The ride I hurt it on was almost completely flat and i spun gently up the only hill because by then my legs were already sore.
