BOSTON (AP) Running the Boston Marathon requires endurance, but 8 1/2 feet of snow and lots of treacherous black ice are testing this year's participants in frustrating new ways.
With race day less than two months away, the brutal weather is sending some runners indoors to basement treadmills and health clubs - and driving others just plain nuts.
Though the worst of the winter now seems past, there are only 48 days left until April 20, the 119th running of the venerable race.
Athletes say time is running short to get legs and lungs in shape. Many streets and sidewalks remain slick, making it dangerous to share narrower-than-usual roads with drivers and log 20-mile training runs.
Some runners are doing multiple laps in quiet neighborhoods to avoid cars hidden by huge snowbanks.
