In Vorarlberg, the infrastructure was outstanding. We based ourselves in Bludenz, the home of Milka chocolate (My kids had obscene amounts of chocolate during the annual festival, but that is another story). It is located at the junction of 5 valleys and I was able to explore 4 of them. 3 had outstanding cycle paths, 20-30km long, 3m wide, mainly asphalt with a little (<10%) gravel. They were all well used by a variety of cyclists (local commuters and shoppers, tourists with panniers and those out for long fast rides), even when I was out at 6am. Also they fed a huge number of MTB trails off the paths.
On top of that we hired bikes as a family ride from Bregenz for a trip on the Bodensee path. My 9yo and I did the ride to Rohrschach in Switzerland where we caught the ferry for Lindau in Germany. A quick return to Bregenz meant 3 countries in 30 miles and a tired but happy 9yo. Interesting that on the ride the Austrian infrastructure was far and away the best, Swiss lagging a bit behind and the 8km of German was equivalent to Scottish.
I also did a quick foray into Liechtenstein on another ride and would like to go back and explore the whole area a lot more
My annual holiday day pass was well used to follow some of the 2018 road world championships courses in the Innsbruck region. I was staying in Alpbach in the Tirol and descended to join the men's time trial course in Reith. Then joined the road race course through the villages before climbing steeply to Gnaderwald and then descending to Innsbruck centre to try the finishing circuits. The first one climbs 500m at 10% to near Paetsch and then drops super fast back to the city centre. Fine to do once, but not 6 times!
The final circuit is extended to include the road to Hoell which climbs 400m at consistently over 20% and hits 28%. I had to walk the last 50m of that section. Another fast descent to the finish and a gentle following of the Inn trail made for a lovely ride. The sting in the tail was needing to climb 600m in 10km to get back to Alpbach. These world champion will get worthy winners, I'd guess Nibali for men and van Vleuten or van der Bruggen for women.
The route was lovely, but the roads did suffer some aggressive drivers.
