Thats what, 31 miles? In a group, I would think you should be able to do that.
I'm supposed to go do a ~30 mile ride on Saturday with some peeps from bikeforums. Would be around 34-36 F starting, high is only supposed to be 50 for the day, but light wind, so we'll see I have only done about 15 miles for the longest ride so far since winter seems to be hanging around.
