Can I collaborate without riding a motorcycle?

Without a doubt, the cause is worth it and we know from previous editions that there are those who want to participate even when they will not be able to do many kilometres or do not even have a motorcycle. Cancer makes no distinctions and neither can we… so, if you want to collaborate, you can always register in either of the two options, purchase solidarity merchandise (scarf, keychain, embroidery, buff…) or make a contribution.

Also, if you register... you will participate in the raffle of fantastic prizes!

Can I collaborate without riding a motorcycle?

Collaborating is great,
but what if in addition...

you could win fantastic prizes?

With your registration you will receive a raffle ticket… and one additional ticket for every 100 km ridden on your motorcycle. The main prizes will be sent to your home.

Raffle and prize delivery details will be published before the edition starts.
