How long is it and how often do you do it?

We just put an offer in on a house that is a bit further away than we had originally planned. If I'm willing to climb the ridge between the house and my job, it'd would be a 16 mile commute with about 1500 to 2000 ft of climbing. If I go around the ridge, it's 19.5 fairly flat miles with only about 5 of those in town/city.

Is that too long to expect to do it every day (once I get conditioned to it)??
