Thank you very much@Erik v S
I take a look at the links.
These days I am busy following the -Transiberica bike Race- :
,a ultracycling race across Spain and Portugal, in the style of the Transconstinental in Europe, or the Trans AM in North America, it is self-supported bicycle race where every biker follow your ownroute to reach the finish, only exist the obligation to pass for the marked Check Points.Participants generally takes a racing bike ready to bikepaking and they are followed by a Traker GPS for the organization.It is very exciting to follow the Race,since bikers cycling the night and doing 300-400 or more kms. by day treating of doing the less time possible.
Maybe I open a topic in the forum about this Race.
It is possible to follow this Race here: https://www.transiberica.cc/
or in the Facebook of the ultracyclist italian Omar di Felice: https://m.facebook.com/omar.difelice/
