A Brattleboro, Vt., man’s planned cross-country run to raise money for homeless teenagers is raising questions among potential contributors, reports The Barre Montpelier Times Argus.

Tellman Knudson, a millionaire Internet marketer who says he overcame a crippling leg condition, has received extensive local press for his campaign to run the equivalent of a marathon a day from New York to Los Angeles in his bare feet, starting September 9.

Visitors to Mr. Knudson’s fund-raising Web site are immediately asked for their names and e-mail addresses, and those who sign up receive e-mail messages referring them to the site of Mr. Knudson’s business, Overcome Everything Inc., which has been the subject of complaints on online forums about repeated solicitations for credit-card numbers and alleged unauthorized billing.

In response to the complaints, Mr. Knudson says, “Every business has its hiccups and growth curve. If you want to grow and you want to improve, you’ve got to screw some [stuff] up along the way.”
