To add a bit here, in addition to total elevation, you'll also commonly see tougher climbs on a ride broken out with the elevation for them segregated from the total amount in many cases. A lot of more serious riders like to test their performance on particular climbs and are interested in tracking both the elevation gains and the gradient increase percentages for those. This is especially true for those who perform well on the flats, but are a bit "allergic" to hills
