This is a great thread. I can't imagine 5 halfs that close right now, but I hope i get there someday because there are so many races I want to do. As I'm currently planning to run 3 halfs, the last of which is the Glass Slipper Challenge in Feb and the first is Wine & Dine in Nov with Tink in the middle, I'm following along with interest.
Due to some unfortunate injuries this spring, my long run mileage WILL be peaking around 13 miles before the 1st half. Originally that I was not my plan, but that's what it is now. Here is my current tentative plan between W&D and Tink & GSC as far as weekly "long" runs:
W&D (13)-4-6-7-8-5-9-10-8-5-Tink(13)-6-8-10-5-PHM(13)
I'm trying to go at it from the perspective of total mileage in every 2 week segment. Not sure if that will work, but it makes sense in my mind.
I've only ever done 1 half (W&D 2012) and I ended up slightly injured, and I'm a bit injury prone, so I'm hoping to just make it through these races. PRing at this year's W&D possibly but Tink and PHM/GSC I just want to get through them and am looking at it more as whole than 2, well 3, races.
