This gurl doesn't mess around when it comes to fitness!
Alison Sweeney, the host of Biggest Loser, hosted Prevention Magazine's "On The Run" event in San Diego on Saturday, which she also participated in to prepare for the upcoming L.A. Marathon.
Runners had the opportunity to race FOR FREE in the third annual event's 5K, 10K or half-marathon length course, while kids could take on the 1.5 mile "Mini Mermaid Run".
Alison completed the 10K race through the SoCal city's Mission Bay area with a personal best time, so we have no doubt she is going to kick butt in El Lay this March when she runs a full marathon!
