Check with your local bike shop and the race website they may have information on transporting your bike. Most bike shops pack your bike in a cardboard box they have from another bike. They will ship it for you most big races have bike shops in the area that will receive your bike and put it back together for the race. If you do not like this option some bike shops will rent you a box for checking you bike on the airline. There is a cost involved in flying your bike and you will also have the issue of needing to assemble your bike once you arrive. Personally I like option one and just do the reverse when the race is over to get your bike home.
