Kayleigh McManus (28) who hails from Portadown, Co Armagh knocked over in the stampede away from the bulls on Sunday morning.
Friends feared for her after she was taken away to hospital in a neck brace but Kayleigh laughed off her injuries.
"The shock of the injury hasn't taken away my wish to keep on running. The adrenalin is incredible. "
Ms McManus was injured in a collision with another runner and was knocked unconscious.
She said that her injuries looked a lot worse than they actually looked and she was looking forward to returning to the world famous festival next year.
Other runners weren't quite so lucky.
A bull gored three men after breaking away from the pack chasing crowds through the streets of Pamplona in the closing run of the San Fermin festival yesterday morning.
The animal charged several runners in the town, lifting at least two of them off the ground on its horns and ripping through their legs.
Two Australian men were wounded - one of them, a 26-year-old, seriously - alongside a Spaniard, 21, from the surrounding Navarra region, said authorities.
For a week every July, hundreds of people dressed in white with red scarves join the daily "encierros", when bulls chase them through the town's narrow streets into the bull ring in a festival that has grown into a global tourist attraction.
Several men have already been gored this year but Monday's run, the eighth and last, was particularly brutal.
