Antelope Canyon. My first 50-mile ultramarathon. Wow. Where do I begin.. This race experience was, without a doubt, one of the most incredible race experiences I will probably ever have. I’m sure many people say that about their first 50-miler or 100-miler, but this race was meaningful in ways that were very specific to the time and people who were involved in the months leading up the race and at the race itself, including a finish line experience that was truly once-in-a-lifetime.
