Krystine Rivera had a bad day at work and was waffling over whether to head out for an 11km run. She decided to go for it. And then her day, as she says, "got astronomically worse". She was hit by an airborne deer. Rivera, 27, was jogging on a path adjoining Claiborne Parkway in suburban Ashburn, Virginia, about 6pm Thursday, when a deer "came out of nowhere" and was hit by a 71-year-old woman driving a SUV. The impact sent the deer flying into Rivera, knocking her unconscious. She remembers only running one minute and then coming to in an ambulance as a paramedic told her he needed to cut away one of her favorite running shirts "because it had deer blood all over it". "That's when I knew a deer was part of this," Rivera said. She doesn't recall seeing the deer as it sailed toward her. "I was running, then I was on the ground and then was listening to the paramedic. I'm surprised I made it out alive. "I thought that the run would make me feel better after work," said Rivera, an administrative analyst. The buck died at the scene. The driver was treated at Inova Loudoun Hospital and released, according to the Loudoun County Sheriff's Office. Rivera, who was taken to the same hospital and also released Thursday, suffered a concussion, a cut to her scalp and a bruise to her right knee. "My whole right side hurts," she said. Barely 1.5 metres tall, Rivera already had been jokingly nicknamed "The Hulk" by her friends. "So I guess now they can really call me that," she said. She had clocked about 8km Thursday in her neon orange running shoes and was on the final stretch toward her home in Ashburn when she was hit by the deer. A female passerby called emergency services and used Rivera's phone to dial numbers that reached Rivera's boyfriend and her family. "I want to really thank her, whoever she was. And I am glad the driver is all right."
