That's about 28.5 kp/h, which if the course is not totally flat, is pretty fast by my standards. On most of my long rides (100 mi and more) I don't even average the brevet minimum of 15 km/h, admittedly usually in hilly terrain. If a distance feels too hard, you can always drop the pace a notch or two
