This is a rolling ride through some lovely country and town roads that pass by several bodies of water in Southborough, Westborough, Northborough, Marlborough, and Hopkinton. The short ride has a few hills and is mostly north of Route 9. The long ride is more rural and adds Hopkinton. The routes are not marked and as there are lots of turns, Consider GPS navigation or plan to ride with someone who has. Rain, snow, or sleet cancels.
Chestnut Hill Rd in Southborough is closed. As of 3/12, it had not been plowed and was impassable by road bikes due to snow. This comes at 15.5 miles on both rides. Going straight on Route 30 will skip this little loop, subtracting a little over a mile from both rides.
