Assuming you have a smart phone, the workout apps like Strava will tell you how much climb there is in a route, as well as mileage and elapsed time, etc. The first year I had it (for cycling) I was always trying to set a PR. That'll get your attention- beating your prior self each time. You can also compare your times to "segments" that others have logged with Strava.
Last week when we hiked I forgot to stop Strava back at the car, so it was running as we drove home. Got an email notification that I was now cycling KOM (King of the Mountain) for the Sheffler Road climb segment. Too funny. Let's see some cycle-wanker top THAT! 50 mph up that hill. I was dyin' by the top, haha.
