I set a goal to run 1000 miles this year. A friend of mine has done this every year for the past 5 years and when I read about it I thought it was better than setting a new year's resolution like "exercise 5 days a week". This is a fun goal - run or walk 1000 miles this year. I hit the 500 mile mark today and am so excited about the progress. It took so long to get to the 100 mile mark but since then it has gone much faster. It doesn't hurt that I'm putting in 30+ miles a week right now in training.
