Congratulations on your entry into the 2019 Western States 100-Mile Endurance Run. As demand for the race continues to increase, getting a spot in the race could possibly be the most difficult part of finding your way to the finish line in Auburn.

This is the first of several updates you will receive from me leading up to the pre-race meeting on Friday, June 28 up at Squaw Valley. These are important updates that will also be posted to the WSER website. To stay up on the latest news you may also wish to follow us on Facebook,

Wait List and Refunds
As we have since 2017, we are using a wait list to ensure we start the allowed 369 runners. You can view the wait list here.

If you must withdraw for any reason, the next person on the wait list will be given the opportunity to take your place on the start line. We will refund part of your entry fee if you withdraw:

75% if you withdraw by May 1, 2018
50% between May 2 and June 9, 2018
25% between June 10 and June 20, 2018
no refund after June 20, 2018
Service Requirement
Since 1998, WSER has required eight (8) hours of volunteer service by each entrant, no matter where you live. The WSER Board has a strong preference that runners perform their service in support of an ultra or doing trail work on a trail used in an ultra, but will accept service provided to any organized running event or trail work done on any trail commonly used by runners. Please submit the SR form to us by June 1, 2019. Please don't wait until the last minute to submit your form. Look here for confirmation that we have received your form.

Western States Store and WSER Logo
Branded merchandise is available at the WS Store. It is always available online and will be physically setup at Squaw Valley before the race.

If you are planning on making your own crew shirts, you may use the WSER logo as long as you don't sell the shirts. Please respect our intellectual property. 
Training Runs
There are four training runs scheduled before the race which offer an opportunity to get time on the final 70 miles of the course. On Feb 9  we'll run the last 20 miles. On Memorial Day weekend we have three training runs on three successive days over the final 70 miles. These runs are open to anybody. If you are planning on doing them, sign up early as each of them fill to capacity.

If you have any questions, don't hesitate to contact me.

Train smart,
