My wave crossed the start right at 9:45am.
At the start, I felt no issues, completely ready for the race.
People had noted that the first 5K is a net downhill and not to go out too fast. I really took this to heart and almost treated it like an easy warmup, keeping myself at around 7:40 min/mile pace.
I only consumed two gels, the first one was early at like mile 3 or 4.
I think the next must have been around mile 7? I’m not sure.
As the race progressed, I felt like that was actually a fairly comfortable pace and my instinct said not to kick it up a notch.
I ran mostly by feel and didn’t concern myself too much with the pace from here on out.
Around mile 23, I was feeling a bit overwhelmed and started to take a few quick walk breaks, which did help to “reset me” and get me back to running after a minute or two.
Just like with the Disney World marathon, I was just overall exhausted, and can’t really point to a specific issue.
I was feeling myself sweat more than usual. I didn't notice feeling too warm until the last half.
There was a point towards the end where I felt very thirsty, but my stomach wasn’t feeling stable enough to drink anything. I wasn’t totally sick in the stomach, just feeling like I was getting to that point.
I felt a little loopy towards the end
