My New Year's Resolution ...
Over 20 Miles of Pain
Most people sign up for some spin classes ... but "Biggest Loser" host Alison Sweeney is taking that 26.2 steps further for her New Year's resolution -- telling TMZ, she plans to run the L.A. Marathon this year.
She's got 76 days left to get ready -- the marathon is scheduled for March 18 -- but Alison tells us, she already got a head start ... beginning her training two months ago.
Sweeney says she plans to hit the pavement with several "Biggest Loser" alums on the big day. Now that's commitment.
