The annual Warrior Dash is being held this weekend, one week after a 30-year-old competitor died in a different obstacle race.
The first wave of about 13,000 people will take off at the Warrior Dash on Saturday morning in Roanoke.
The race is not related to last week's Original Mud Run, where 30-year-old Tony Weathers died. His friends saw him enter the Trinity River but never saw him come out.
"It kind of scared me because I have seen stuff happen at other mud runs," said Chelsea Blake, who is participating in the Warrior Dash.
"I'll take it slow," she said. "I don't do it for time, I do it for fun."
Morgan Bucciferro, who helped organize the Warrior Dash, said safety precautions have not changed. Medics will be stationed at every obstacle.
And unlike the Mud Run, the Warrior Dash has only one water obstacle, which takes place in a 4.5-foot-deep lake, Bucciferro said.
She said two lifeguards would be stationed at each side of the lake.
The Warrior Dash has had controversy in the past. Two years ago, it was almost shut out of Kaufman County because the proper permits weren't secured to have the race. This year, Denton County granted what's called a "mass gathering" permit for the event.
This is the second year the Warrior Dash is being held in Roanoke. The race goes in waves from 9 a.m. to 4 p.m. on Saturday and 9 a.m. to 3 p.m. on Sunday.
