MILWAUKEE (AP) -- A group of 62 runners is trying for a Guinness World Record at next weekend's Milwaukee Lakefront Marathon.

They plan to tether themselves together with a long rope and carabiners attached to their belts.

They're hoping to raise $75,000 for the rehabilitation care for runner Jenny Crain, who was hit by a car in 2007 while training for the trials before the Beijing Olympics.

The team is calling themselves the "Jennipede."

The race Sunday morning is expected to attract more than 3,000 runners. It begins at Grafton High School and ends along Lake Michigan in the downtown Milwaukee area.

Twenty-six-year-old Amber Druien, of Woodstock, Ill., will also be there in hopes of qualifying for the Olympic Trials.
