Loren Zitomersky, an experienced runner, said he is planning to run all 26.2 miles of the Boston Marathon while facing backward in order to raise money for the Epilepsy Foundation of Greater Los Angeles. Advertisement Zitomersky, whose brother, Brian, died of epilepsy-related causes at the age of 7, said he is also aiming to break a Guinness World Record by finishing the marathon with a time under 3 hours, 43 minutes and 39 seconds. Zitomersky said backward running has caused him a lot of pain in his legs, but it doesn't compare to the struggles faced by epilepsy patients. "The pain and the struggle that I'm feeling when I'm running backwards is temporary," he told KABC-TV. "For them, they live with this struggle and the difficulties every single day."
