What race day looks like

Sand Harbor 5K and 10K runs at Sand Harbor, NV, and like everything we put on, it is built to be genuinely hard and genuinely welcoming at the same time. The front of the field will race it. Everybody else will finish it, and get the same welcome at the line.

You will be racing at altitude. The course tops out around 6,250 feet, so if you are coming up from sea level plan for paces roughly 10–15% slower than home, arrive a day early if you possibly can, and drink far more than feels necessary. The sun up here is stronger than it looks.

Aid stations are stocked and staffed by volunteers who will know your name by the second lap. There is food, a raffle and a cold one from Alibi Ale Works at the finish, and the whole thing runs under permit on public land we intend to leave exactly as we found it.
