Excellent.
If you're hitting your goal this early in the year, now's the time to think of a Challenge Goal for this year, and where you'll set your goal for next year.
I've been doing this for many years now and have a pretty good idea of what works for me. As of this morning, I have 4496.26 miles towards a goal of 4800 and a challenge goal of a mile of miles, or 5280. I expect to come in around 5000.
I'm not saying those are the numbers you should shoot for, just an example of what I mean.
