Last week I heard Rick speak to this saying something along the lines that shuttling between events was going to be nearly impossible. Great article by NYT (gift link) expands. The paragraph below the link had me laughing out loud as an experienced user of public transport in the Dolomites.
According to the app, the “best route” from the curling and bobsled events in Cortina, in the Dolomite mountains of northeastern Italy, to the snowboard competitions in Livigno, on the border between northwestern Italy and Switzerland, is to walk eight minutes, take the TC-CO-AS transport shuttle for 3 hours and 3 minutes to Venice; walk another four minutes to catch the 9748 high speed train for 2 hours and 15 minutes to Milan’s central station, where, after a walk of five minutes, one can take the 9074 regional train for 2 hours and 39 minutes to Tirano; then walk another two minutes to the bus station, catch the TC-VA-01 bus for 50 minutes; then change to the TC-VA-02 bus for nine more stops and another 1 hour and 12 minutes and walk nine minutes to the competition site.
The estimated travel time is 18 hours and 6 minutes.
