E-Transpyr C2C has the same regulation as Transpyr Gran Raid MTB, with the following caveats:

1. Electric bicycles participating in E-Transpyr C2C must meet the following requirements:

• Provide electric help only when pedaling. The installation of mechanisms that make the engine run without the movement of the bottom bracket by the cyclist is not allowed.
• Maximum assisted speed: 25km / h. From this speed the electric aid is disconnected. The help button when walking is allowed. It is not allowed the installation of mechanisms that cancel the disconnection of the engine at 25km / h.
• Maximum motor power: 250W.

Participants in E-Transpyr C2C may be required to pass technical checks prior to departure and upon arrival. Random checks might be performed by the organization.

2. Charge: The organization guarantees the transfer of batteries to the feeding stations. For station 1, the battery must arrive at the Race Office the day before. For station 2 and 3, the batteries must arrive at the latest at 7 in the morning. It is not the function of the organization to charge replacement batteries for the participants.

3. Departure time: the organization may give the start of E-Transpyr C2C, before or after the other cyclists.

4. Finisher recognition: participants in E-Transpyr do not have the same Finisher recognition as participants in Transpyr Gran Raid MTB.

Transpyr Gran Raid MTB offers the possibility of living this unforgettable adventure in a relay format. In that modality, you can enjoy the changing landscapes of the Pyrenees and share the extraordinary mission coast to coast with your group of friends.

The teams may decide at each stage who starts in the first relay and who in the second. They must inform Race Office before departure.

Participants can choose in which of the three feeding stations to perform the relay, although it is advisable to do it in the second (accessibility with vehicle).

Participants are obliged to carry one geolocator booked at the race office and that will serve as a relief.

In addition to the geolocator, the GPS will also be passed to help the organization verify the route.

Each team is responsible for organizing the relay logistics on their own. The organization does not transport to the place of the relay or at the end of the stage.

Those enrolled in this modality will be subject to the regulations of Transpyr Gran Raid MTB.

Those enrolled in Transpyr Relay C2C do not qualify for the Finisher Transpyr Gran Raid MTB distinction.
