Adaptive Re-use?

Adaptive re-use usually refers to using old  buildings for new functions, such as converting an old tobacco factory into trendy residential lofts. But what about using an old limestone mine for underground bicycle racing? This may seem like an odd comparison, but I think it's a pretty cool new use for an otherwise depleted space.

The annual race is called the Underground Cup and has been taking place in Budapest for the last four years. The underground course offers challenges unavailable above ground and cool temperatures for the participants!
