I have been to the athletics venue in Beijing. They have turned it into an ice playground with go-karts, a small ice-skating rink, and several other snow-related games. Inside the stadium itself they had photo's of the medalists and equipment with explanations. It cost a couple of dollars to enter and it was quite busy, so I guess they were able to cover maintenance cost from the entrance fees.
