Time to do some test run for Quebrantahuesos: Ports del Maresme, a 150k race around the climbs we all know. Starting from Arenys del Munt the route is along the climbs around Mataro and Montseny, with a total of 5 climbs and 2600m climbing.
More info here:
We can get there by train (really early!) from Arc de Triomf or Clot-Arago. There is a train at 6.19 am (!!!) at arc de triomf that will be in arenys del mar at 7.11. then there should be enough time to go the 3km to arenys del munt and pick up the race number.
