i haven't done that ride, but it shouldn't be too bad. head south and either zig zag your way south and west or take broad st west to the bike trail. once you are there, you can pretty much straight shot to xenia where you can take ohio route 1 to yellow springs. or, if you want to cut down on time and mileage (about 10 miles), you can exit the bike trail at cedarville. from there, you could take clifton pike to clifton and then head west to yellow springs on north st or take cedarville-yellow springs rd and head in to town on the trail by cherry st. if you do opt for the second option, there is a pretty nasty climb that you can attempt on the way in to town just a few miles out - the devil's backbone on bryant park rd. good luck!
