A jogger has warned other women not to go out alone in the dark - after being attacked by three men near her home.
Cait Smith, 23, was attacked from behind by a group of men who pinned her to the ground.
The terrifying ordeal happened on Tuesday in Castle Park in Colchester, Essex.
The young admin assistant was left with dark bruises to her arms, and scrapes and bruises on her face, as well as a swollen black eye from having her head "smashed" against the ground.
Cait has been flooded with thousands of messages and comments of support since posting on Facebook on Wednesday morning about the assault.
And she is now warning other young women and men to be aware of the "dangers" of going out in the dark.
She said: "It's terrifying that other young people like me should have to live by a different clock out of fear.
"But that is what I want other people - not just women, but everyone - to be aware of. I don't want this to happen to anyone else.
"From now on, when I feel able to go out running again, I'll be sticking to busier areas."
Cait was out for a run on Tuesday night at around 10pm when the assault happened.
She said: "I run in Castle Park a couple of times a week, and I've never felt threatened down there.
"I normally wear a head torch when I'm running, so I can keep my wits about me. But typically, this was the one occassion where I forgot it.
"I had stopped running for a moment to change my music on my phone, and I got grabbed from behind - I didn't even see it coming at all.
"I was wrestled to the ground, and one of the men was sat on top of me, while another was holding my head to the floor.
"I've been left with a big lump on my face from where they smashed my head to the ground."
Cait said there were no other people around to come to her rescue.
But she said: "I'm lucky that I'm quite feisty - I can hold myself in a fight.
"I don't think they were expecting me to fight back - so I just fought as hard as I could and then legged it away from them.
"I don't live that far from the park, so I was able to just get myself back home.
"But if it was any other person it happened to, maybe someone a bit more vulnerable, they might not have been as lucky as me."
Cait said that from now on, she will stick to running in the daytime, and in busier areas of the town centre.
She said: "It's not right that women, or anyone, should have to avoid going out at night because of fear that they might be assaulted. Things have to change."
Chief Inspector Jon Evans, District Commander for Colchester, said: "I understand this will be a concerning incident for people living across Colchester and who use Castle Park regularly.
"No-one should feel afraid for their safety when going out alone, but we are working to identify those involved.
"Fortunately incidents such as this a rare in Colchester, but we have additional patrols in the area to provide some additional reassurance."
