Have only been riding a tandem 8 months. For those with more "road-ish" tandems, I'm curious what your average speed is after, say, a 25-50 mile ride that doesn't really involve a lot of climbing. I realize that it's hard to pin down because of different terrain, different bikes, etc. but I'm a numbers person and I'm curious. I'm wondering if we ever ride with other tandems whether we might fall in the first third, the middle third, or the last third. Just a curiosity since we have no experience with riding with others.
