I try to do one tour of a month or more per year if possible, now before I retire. I have not managed to do that every year though. So far I have managed a 73 day tour, missed a year due to injury, did a 10 day tour, and did a one month tour.

I expect to tour two or three months out of the year after I retire. That seems about right to me since I have no desire for shorter tours than 10 days or so and the round the world thing doesn't interest me. Then again I have other interests that might compete for my time so who knows. I might end up running coast to coast, sailing, backpacking, or kayaking instead some years.
