The thing I love about Minneapolis is their bike rental system called Nice Ride similar to the Velibe in Paris. For $6 a day and $1.50 an hour depending on how long the bike is checked in and out across it's numerous rental stations, you can get around basically anywhere in the twin cities core metro including a large part of the Grand Rounds trails. When you're tired you can check in the bike to a station and walk to a nice cafe or restaurant around town. The great part of the Grand Rounds trails is that it hits all the pretty sections of the city like Uptown, Chain of Lakes, UM, Downtown, Minnehaha falls, Nicollet Island, East and West river parkways, etc. you can tour a large part of the trails and Minneapolis by bike using Nice Ride and if you check in and out the bikes every 30 minutes you don't pay anything except the $6 subscription. Minneapolis really makes it easy to tour the Grand Rounds and get around the city by bike.
