Never running a 50K, I thought it would just be a marathon with 5 extra miles tacked on. Wrong. Around mile 18 it hit me, I still had a half marathon to run. The course itself is flat, and it’s a trail I have run thousands of miles on during training. None of that prepared me for running 50K in one shot. The aid stations were great, however it did seem like the race was focused more on the relay aspect instead of the ultra. It is demoralizing to get passed by so many fresh legs when yours are giving out. Still a good experience for an ultra marathon. The logistics were good, and it was definitely a party atmosphere at the finish.
