Lake Sammamish Half Marathon Race Info

Lessons Learned from Race Reports

  • It’s a very fast course, though the smooth gravel section near the middle of the race, miles ~5-9, does slow your pace slightly
  • Past years have seen very good weather, in the 50s, especially considering it’s the PNW, but be ready for rain regardless
  • There are some very short switchbacks at the start and it is a fairly narrow pathway for about the first mile – be aware because it is hard to pass people. If you’re going for a fast time, it’s worth putting in a small burst of speed to get out of the fray and establish a front position.
  • 2018’s race saw mile markers incorrectly placed, which lead to a lot of confusion and angry runners – be aware this could happen and don’t depend just on the markers to gauge how your race is going in terms of pacing and feel
  • There is a bridge to navigate about 800m into the race. If you get stuck in the middle of the pack, your group could bottle neck.
  • When you reach the state park it’s safe to start your kick for home and push to the finish.
  • The race often draws lots of competition, so if you’re fast, you’ll likely have some fast people to run with who are going for PRs.
  • Course is mainly shaded, so if temps are cool, expect to feel a little chilly, even if it’s sunny
  • The first two miles or so consist of trails to and through Marymoor Park, heading towards the East Lake Sammamish Trail (ELST).  These wind a bit, so follow the tangents if you can.
  • There’s a wood bridge around miles 3 or 4.  It was only a few steps to cross, but it was really slippery.  There was a volunteer and sign warning about it.
  • As of now, the course goes from paved to gravel at about 5.5 miles.  The gravel is in good shape but can have some puddles and mushy parts.
  • At about mile 11.5, the course turns right and then there is a ~1 mile straightaway and you can see the whole thing. This is great for seeing runners ahead of you but a little tough mentally because it just keeps going. Then it heads into the park and makes a few turns. The finish comes up a little quickly though it’s not just after a blind corner.
  • There aren’t that many turns, but the signs tended to be just after you started worrying about which way you would have to go but definitely before you actually had to turn.

Spectator access

Access Locations: Very few because it’s a bike path that runs along private property, so it’s very hard to find parking and/or public accessible locations along the way, and homes along the way are very sensitive about public access and parking. Best location is the finish at Lake Sammamish State Park.
