I would say that it's pretty safe to hold a sporting event anywhere because sports are usually deemed untouchable.

The theory is terrorists are themselves sports fans and they know the general public are sports fans and attacking sports would allienate them.

For example, the attack on Sri Lankan cricket players in Pakistan earlier this year backfired because no longer can cricket be played in Pakistan and the World Cup was taken away from them. This angers all fans who will no longer support the terrorist cause (if they did in the first place)
