Rochester Active Sports Club (RASC) is a nonprofit club based in Rochester Minnesota, designed to promote nordic skiing, mountain biking and road biking in SE Minnesota.
At the request of many bicyclists, the Minnesota Dept. of transportation has developed a series of county level bicycle maps. There are 125 maps with some counties split into more than one sheet. You can click on a county name to see trails, road conditions and more. Print the maps on 8.5x11 or 11x17 paper to take along to help navigate your trip.
Go to https://www.dot.state.mn.us/bike/routes-maps.html to scope them out.
This map is one adapted from one originally drawn up by Paul Scanlon (thanks Paul) and has not been updated for about 20 years, so please use with that in mind. The map can be printed on both sides of a single page and shows most roads suitable for road biking within a ~15 mile radius of Rochester. This is a useful map to have in your saddle bag for the day when your iphone / garmin stops working and you're trying to remember the best route home!
