Will marathon organizers give you a refund if the race is postponed?

Marathon Refund?No.

Well, that might depend on the race and the reason for postponement but in general your entry fee will be applied toward the next race. These terms are usually spelled out as part of the entry form when you sign up. Very few races will give cash refunds except in very unusual circumstances.

Ask the race organizers or read the contract, here we can only guess.
