Started with the 1:50 pace group/11:00 min mile. After about half way mark, I drifted ahead so I could have some extra time at the rest stop at mile 6.5ish. I tried to eat my gel leading up to that, but it was hard due to it being so cold. I drank a water and a Gatorade and then decided to use the potty. Surprisingly I was still head of the pace group after all this, so I decide to hit the gas as much as I could. Other than a few steeper hills, I was able to increase my pace gradually towards the end. I felt pretty great and I am super happy I started with the slower pace group. Definitely a better choice for me, I hope this works in future races.
