My view of the half course is very jaded by my W&D experience. I’m really hoping they do something differently, because it was pretty awful.
For those who don’t know, the way they did W&D corrals was the standard lettering system… but also each letter was then divided on-site into multiple corrals. So while I was in D, D actually comprised 3 or 4 physical corrals, each named a different color. The deal was that they filled the first of a letter’s corral, then closed it and started loading the next one. Once a corral was closed, there was NO further entry allowed. If you were already in a corral that closed, you were allowed to exit to use the potties or get water, but had a 10-minute return window and had to provide a password to get back in.
I was loaded into the 2nd corral of D and started at the back of it, as I usually do: I have serious issues with feeling trapped in a large crowd, but hanging back in my corral and staying off to one side usually gives me some space and also means having time and room for things to spread out once we actually get moving, before the first wave of the next corral starts behind me and also spreads itself out some. That did not work with the new W&D system. Though they loaded D into 3 or 4 separate corrals, they released them all into one enormous group to walk to the start. And while they seemed to do mini-wave starts, they went FAST: fast enough that things didn’t spread out at all for me. Truly, the entire 13.1 miles was uncomfortably crowded. The BW path was horrendous - we came to a complete stop at the water station. Passing anywhere other than the widest parts of highway was nearly impossible without getting in someone’s way. It was tied with the first Dark Side 10K for the worst race experience I’ve had, only minus anything Star Wars-y to take the edge off.
So, seeing how much of that half course is narrow and how early on it falls is not encouraging from my vantage point. I’m really hoping they don't repeat the W&D system and/or that they take more time between mini-waves.
