Lessons Learned from Race Reports

  • Not tons of spectators on the course, especially with such an early start, so if you really like crowd support, this may not be your favorite race
  • Even with such an early start, it can still get quite warm for the race once the sun comes up
  • Speaking of an early start, 5:30 is EARLY, so that means plan on shuttle/parking/drop off in the 4-4:45am range
  • Second half is a little more boring scenery compared to the first half, so have mental tricks for getting through the second half, when you’re likely tiring
  • Small out and back after mile 15 which has a sharp u-turn, which can feel fairly jarring that late in the race
  • While it’s overall a fairly fast, flat race, there are a fair number of turns, some greater than 90 degrees, along the course, which can slow you down and break your rhythm
  • Many more runners do the half marathon, so the marathon feels fairly small and gets fairly strung out over the course of the race – be aware of this if you enjoy running with lots of people and/or groups
  • Second half of the race also narrows, which isn’t a huge problem since there are so few marathoners compared to half marathoners
