I'm getting more confused about what I should do for Detroit.
Plan was to show up with the 3:55 (9 min pace) group, run for half the race with them, and then cut lose around the half marathon mark. Run seven at a moderately hard pace, and blow out the last 6.2 with whatever I have left- hopefully more than the previous seven.
I imagined doing 3:46, cutting an hour off last year- my current marathon PR. But after running the 20 miler yesterday at an 8:11 pace, and realizing that it would give me a 3:34 marathon if I were able to keep it up for another six miles... it makes me wonder.
What could I do if I blew it out? If I followed my plan, but signed up with the 3:42 (8:30 pace) rather than the nine?
It's a risk.
But most things are.
