In the next few weeks Run Disney will issue an event program (google: "run disney wine and dine 1/2"). If you avoid race locations the crowds can be low. So far the map(s) hasn't been published. If you time it right, the morning of the race, you can ride ToT and RNR a few times in a row with zero wait time. EPCOT and MK tend to be crowded over the race weekend.
