The event consists of 7 categories: single (female or male), doubles (male or female), mixed doubles, trios, teams (3 cyclists), company teams and press teams.

The route can be cycled completely or in relays. In the relay categories at least each one of the participants must complete one of the sections between official control points.

For a category to be officially recognised there must be a minimum of five registrations in it.

The price per participant is 180 € - past March 31st 225 €-. On the day of the reception when the numbers are handed out and registrations are confirmed, 100 euros must be deposited for each monitoring and safety device loaned to the participants. Relay teams will only have one device, which must be carried by the member that is riding in the event. This deposit will be refunded in Seville at the end of the event, when the devices are returned.

The maximum time to complete the event will be 100 hours. Accordingly, the check points and maximum times established at the control points (CP) must be respected.

The event is limited to 200 participants.

The first 100 registrations will receive a commemorative jersey of the event.

Participants must over 18 years of age and possess civil liability and accidents insurance that satisfies the legal requirements for this kind of event. Together with a copy of their insurance policy, foreign participants must present a certificate showing that this insurance is valid in Spain.
