One way. Feel okay, but nervous about climbing. We're all fairly young and will have been training leading up to the ride. I've been thinking about 2A since it's fairly direct, but have been a little worried since some people have mentioned that the shoulders are narrow and it's heavily traffic-ed.
Re: gravel. We'll all be on road bikes so gravel is not ideal unless it's fine gravel.
We're looking at about 150 miles over two days. Should be manageable.
