Dreyer new record by swimming 35km while towing

The 49-year-old started his 35-km swim on Monday and plans to end on Tuesday in Detroit.

The holder of a number of world records for endurance swimming, Dreyer said he expect to set one this time for longest distance swimming while towing a ton of bricks - a record that doesn't at present exist.”Nobody has ever pulled a ton of bricks any distance," he said. "Pretty surprising, right?"

He's doing it without a support boat. One of the dinghies is ready with a radar target so Dreyer will show up on radar screens. He has to feed himself and won't leave the water until coming ashore.

Dreyer is swimming with a GPS tracking device that will post his position online. It also comes equipped with a messaging system. At the touch of a button, Dreyer can send out 3 pre-programmed messages.

One lets his crew know he is all right. A second tells them he is not and to send a boat. A 3rd shows that he is in a life-threatening situation and requires immediate Roadside assistance from the Coast Guard.Dreyer is trying to raise money and alertness for Habitat for Humanity.
