The goal of the founders of DECLIVE SUBLIME was to introduce to the growing Trail Running "aficionados" the best of what Sintra Natural Park has to offer.
A very demanding track created in 2014 has been developed and adapted to this race and includes passages inside outstanding beautiful private properties only accessible to the participants of the event.

The "X'treme" concept has to do with the beauty of the track with it's technical difficulty and the ability to overcome the challenge. Not with the high level of risk for the participants.
