Sounds good. I like the big picture outlook. Yes. But run some strides every now and then. If on an occasional day (once, maybe twice, a week?) you are feeling your oats and want to cruise the last 15-30 minutes of a run, that's good too. Just not most days. Enough for what? A PR? A PR is setting your sites too low. Consistent mileage is an end in itself at this point: more important than your time in this half-marathon is that you continue what you have started. The process of becoming a runner. I'd start at 90 minutes and cap them at 2 hrs.

Jeff, A PR in this half is just an intermediate goal along a very long path. My path involves me becoming the runner I am in my mind. I know my journey will be long and will be filled with trails and tribulations and probably even an epic failure or 4. But I am ready to take the challenge. However, I also know that I am a person who needs goals and something to strive for. So yes while I want to go sub-2 for this half it is really something meant to help encourage me to get my mileage up and encourage consistency.

I'm sorry I didn't mean to ruin a beautiful moment...
