Are you fat biking yet?

If you're looking to plan a fitness-minded spring break, check out these hot spots for the newest cycling trend.

Sneaking in one last trip before the resorts transition from snow to springtime? Though there’s still powder aplenty, try dividing your time between downhill runs and the new mountain bike on the block. Say hello to the fat bike, whose 3-inch-plus tires will have you cruising over snow in seconds. Over the last few seasons, the sport's popularity has exploded, among ski bums as well as off-season cyclists and triathletes, and North America’s top winter sports destinations have taken notice. In fact, many are opening exclusive experiences just for fatties. Here, we’ve compiled six top-notch trips.
