AthleteReg can run a random selection for your event, if you wish to randomize who is able to enter your event rather than have it be first come, first served. In general, entries are accepted for a specific period of time. Random selection participants provide all their registration information including their payment information. Then, AthleteReg staff run the random selection on the specified day, and as participants are entered into a category, they are charged. Other random selection formats are possible.
