A couple of things to consider.
First, you can not park it as it is a TM issue with most parking companies. A German company owns the international TM on Olympics, Olympiad, and just about any variation thereof you can think of. If any of those words appear in the name, in time it will get blacklisted.
Secondly, because of this you may run into some issues with TM in general. All of this comes from the IOC and international courts coming down hard after the announcement of Salt Lake City getting the winter games several years back. Turns out the city itself and the IOC could not even register their own name with all the cybersquatters. If memory serves me correctly, more than 3000 domain names were taken from the registrants and turned over to the IOC. This was one of the first major instances I was aware of regarding so many rushing to register a newsworthy event.
I wish you luck but urge caution regarding too much money, effort, and time in case they come-a-calllin.
For these reasons, a worthwhile appraisal is hard to give should you lose the domain or have to surrender it.
