What's the secret to keeping a Victoria's Secret body? If you ask Candice Swanepoel (left), her answer just might include spinning. Along with fellow Victoria's Secret angels Alessandra Ambrosio, Lily Aldridge, Erin Heatherton and Lindsay Ellingson, Swanepoel will be taking part in a special "Supermodel Cycle" tonight at SoulCycle's spinning studio in TriBeCa. The one-time event is a benefit for Pelotonia, a charity devoted to ending cancer. Sadly,seats don't come cheap (prices range from $1,000 to $2,500), but then again, how often do you get to ride with angels?
