CBS affiliate KFSM says Laura Wooldridge, 39, of Little Rock, crashed in the woods at the trails at Lake Leatherwood.
Bystanders Jared Joseph told reporters Wooldridge was covered in blood and said he saw her walk out of a trail carrying her bicycle.
“When I saw her she was covered in blood, and I was like oh gosh she crashed and then when I got up closer to her and realized what she had done, I went wow we have got to get her to somebody pretty quick,” Joseph told KFSM.
Paramedics assessed her injuries and had Wooldridge airlifted to Washington Regional Hospital where she died.
Emergency crews said the accident happened around 9:30 a.m. Saturday.
