From the Mediterranean to the Atlantic We start in Castelldefels, on the Mediterranean coast, with Bilbao as the destination and the Adventure Country Track (ACT) through the Pyrenees as our main route. The plan sounds straightforward: load the bikes, point them west, and follow as much dirt as possible across the mountains. But between Castelldefels and Bilbao lie hundreds of kilometres of Pyrenean tracks, mountain passes, forests, remote valleys and whatever weather the mountains decide to throw at us. There will be long days in the saddle, rocky climbs, river crossings, spectacular views and, inevitably, a few moments when we'll question why we thought riding off-road across the Pyrenees was a good idea. There will also be the reward that comes with travelling slowly: discovering places we would never see from a motorway and experiencing the mountains at ground level, one trail at a time. On day 2 we will leave the Mediterranean behind and head into the mountains, following the ACT westwards towards Bilbao. First we'll handover the bikes to our 9 participants and get going towards the start of the ACT.
