Although I've never actually trained specifically for a half marathon (they've just come along as part of marathon training), breaking the 2 hr mark has always been a goal. I came a bit closer on Sunday with a time of 2:01:58. That's a PR of about 1 minute if you count an uncertified race that I think was a bit short, or 3 minutes on a certified course. I'm pleased. But its probably the closest I'll come to breaking 2 hrs, since training for road races really isn't part of my future plans.
Its a long way from my first half marathon 5 years ago. I don't remember the exact time...somewhere around 2:34. Its fun to improve but frankly, speed records are becoming less and less important to me. Just getting out there and enjoying the ability to run and experience is more my focus lately.
