Ride 50 miles out of Montevideo and you can cross two departamentos. It's kind of like having a country were all the states are the size of Rhode Island. This was my first 100 mile (161 km) ride a couple months ago. It was a little premature. After 130 km my right knee hurt so much that I basically limped the last 30 km using only my left leg trying to ignore the excruciating pain from the useless spinning of the right. Not recommended, and a little slow. This set me back about three weeks.
