No problem. Right after your later arrival when you pick up your starting packet go to registration tent - "New Registration" and ask for new start time. Our volunteers will give you new wristband with new start time so you will be able to enter start corridor. They also arrange your new start time with timing company. If you late for any reason, try to come before the start of the last heat. If you come to the race after starting the last wave, you will not be allowed to run and will not be refunded.
