Even without such a huge distraction as maybe trying to get pregnant, I find my enthusiasm for big cycling goals waxes and wanes year to year. After 3 -4 years or so of big goals, I find I need a year of just riding for fun to recharge and rekindle my enthusiasm. I think recognizing that each year doesn't have to be a show stopper, bigger/better than the year before, etc., is important to putting it all in perspective and keeping it fun year to year.
