the months of july and august are perfect to ride a few passes, to ride the alps! well, I'm fortunate to live in the middle of this fabulous mountains and therefore I even can start the most bike rides from my front door :-)
passo dello stelvio (2757m), passo rombo (2474m), passo giovo (2094m), passo pennes (2211m), passo gardena (2121m), passo sella (2240m), passo valparola (2192)......it's an infinite list!
some of this passes you can ride in loops, connecting each other in beautiful up- and downhills
of course when you do a 20km climb with almost 2000 elevation gain, it becomes a very very good strength training for your legs - and never underestimate the proud feeling you get standing on the top with your bike ;-)
