Bike Training between Germany and Switzerland

Today I took the train from Zurich to Rafz to meet my old running-friend and duathlete Roger.
He took me on a beautful and very senic tour around the "Hallau", which is in the northern part of Switzerland, bordering to Germany, whose border we crossed four times. The distance was 72 km including four hills, two of them really steep (total altitude was 950 m). Back in Rafz we had 2:49 minutes on our bike-computer with an average speed of 25 km.
