The expo is the region's largest consumer ski and snowboard show, attracting tens of thousands of visitors each year.

It will be held Nov. 20-23 at the Bayside Expo Center in Boston.

North American resorts and retailers from around the world showcase their offerings at this expo. Ski Market stores will anchor this year's sales event, which offers skis, board, boots, goggles, poles, and virtually every other imaginable type of winter gear.

The Expo serves as a colorful kick-off for the season, with hundreds of exhibiting companies on hand to provide information on what's new for the coming ski season. 

Among the attractions are freestyle aerial shows, a new indoor rail jam for the collegiate snowboard/skateboard crowd, ski and snowboard celebrities, a custom-built indoor ski slope to introduce small children to skiing and boarding, interactive exhibits, and contests.

"The Expos are great all-around family entertainment along with one-stop shopping for some of the best deals around for the upcoming ski season," show producer Bernie Weichsel said.

The Boston Expo is showcasing a new fitness challenge by Olympian Doug Lewis, who hails from the Mad River Valley in Vermont. Lewis is a two-time Olympian and World Championship downhill bronze medalist.

The Elite Training Challenge is a hands-on, interactive, physical-fitness area aimed at building better awareness of the value of physical fitness, nutrition, and sports psychology for all athletes of all ages and abilities.

"The exercises are easy enough for anyone to participate. You can basically walk them if you want, or really go for it and test your fitness prowess," Lewis said.

Participants in the Training Challenge can compare their performance with that of World Cup champions Bode Miller and Lindsey Vonn.

Admission to the Boston Globe Ski & Snowboard Expo is $12, with 12 and under free.  Advanced purchase admission for $9 along with the Expo hours are available online from OnTheSnow.com.
