Shortshorts - Nice half! I think you'll be pleasantly surprised how easy 6:00 pace will be come raceday...just don't get caught up in the atmosphere and kill yourself before mile 16. You sound like you've put the work in, trust the training.
Cutter - Damn man, impressive race! I'd be happy with the 15k you split en route in my upcoming 15k. I guess this means you'll do the 5k, and not the 15 at Miracle Miles? Sounds like sub 2:30 is in the bag...good luck in the next week.
