This weekend, three people died while hiking.
Despite all of the warnings of our excessive heat people still ventured out to the trails in this heat.
Unfortunately some of them didn't survive the triple digit temps.
"If you have someone who is not physically fit who hasn't been drinking water, you're talking within ten minutes you can have someone’s body become overrun by heat," said Larry Subervi with the Phoenix Fire Department.
Officials say on Saturday 25-year-old Anthony Quatela, III, of Phoenix, died while hiking with a friend in the Superstition Mountains.
Police tell us the two ran out of water.
The friend also suffered from heat related illness, but is expected to be ok.
Then today a female hiker was found dead near finger rock near Tucson.
And closer to home, a 28-year-old woman died after mountain biking on the Desert Vista Trail.
Fire officials say she became ill on her way down the mountain.
"Our mountain rescue teams got on scene, they had a mile hike up. They were carrying 40 to 50 pound packs so it took them a little time to get there. The two individuals who were with her from what we understand were friends and were both doctors. They initiated CPR prior to us even getting there."
The woman was airlifted and taken to the hospital where she later died.
Officials say she was an avid mountain biker and a personal trainer and although she was prepared...in most cases the heat is nothing to take a chance with.
"She had water with her, she did have people who knew what they were doing, they had cell phones with them. They were wearing appropriate clothing, they started at 6 am, so even when you do everything right, you're still taking a risk if you go out in temperature like we have today."
We also got word that another hiker was confirmed dead in Tucson where it reached upwards of 115 degrees today.
