This seems to be an unpopular opinion, but I had a great time at the Dark Side Half. I've done the WDW Half in January five years in a row (love it), two
Disneyland Halfs (fun, but not my cup of tea), and the inaugural Tower of Terror 10-miler (hated it). This Half is close to a new favorite.
I had been dreaming of running through World Showcase in the dark with the torches lit up since I heard about the old marathon course. After over a dozen trips to four Disney resorts in three countries, it takes a lot to impress me, but hearing Star Wars music piped in with the lagoon and a beautifully lit World Showcase as the backdrop blew me away. It was otherworldly.
I was in corral F and didn't experience any crowding issues because most people seemed to be running the same pace. I thought the theme came through beautifully in the staging area and the corrals. The first five miles were so exciting, between the theme parks, character sightings, music, lighting, and movie scenes playing on huge screens at the top of inclines to motivate us. I thought Run Disney paid a lot of attention to detail. As for the rest of the course, I fell into step with a fellow runner who I had inadvertently been playing leapfrog with since the gun went off. We decided to settle into comfortable but challenging pace for the remainder of the race. I barely noticed a lack of entertainment because it became about the run. Sure, the sun was in our faces for the last 45 minutes, but that comes with the territory of running outside. I wound up finishing just a minute slower than my time this January.
I didn't mind the lack of merchandise because I arrived Saturday and already knew everything would be gone. The event buses were hit or miss, as usual. There didn't seem to be adequate spacing between expo buses, but that's to be expected. My worst ever wait was the morning of the WDW Half at the Yacht Club in 2012, so I made sure to get on the first bus from All-Star Music to the start this time. I did manage to get pictures with BB-8 and Captain Phasma before heading to the corrals, which was a nice bonus. My only big gripe is the medal -- that thing is a monstrosity. I didn't want to wear it at all because it was so big and heavy. The concept art was much nicer.
I'm glad we got lucky on weather this time, and that I got a chance to run such an awesome course immersed in the Star Wars theme. However, I'm not sure I'll do it again. April is usually too hot for an enjoyable half marathon, and Run Disney is approaching a price point I'm not willing to pay.
