I'll be measuring a 50-kilometer outback course on a Rails-to-Trails path this weekend. Since the out and back segments are identical, is it acceptable for the first measurement to be the out segment and the second measurement to be the back measurement? If so it would save a second 50-km ride. That would certainly be acceptable if the course was a 25-km point-to-point so I believe it should be ok for the 50 km.
