Hi. I offer myself as a guide for foreign bikers, for free, just for the pleasure o making new friends. I know a little about Sierra de Guadarrama.There are beautiful mountains and many interesting trails. Is posible to get there by train. I speak english, french and a litte japanese. I ride mostly xc and allmountain. If you live in Madrid or you came around, contact me and lets go together. Normally I go to the mountains every weeekend. During the week I go to la Casa de Campo twice more or less.
