The 100K filled up rapidly this year. We will have a waitlist and it’s likely we’ll accept a lot of people from the wait list as we did last year.

The two courses will be the same that we’ve used for the previous three years, and only slightly different than we used for the three years prior to that. We will have some great food and drinks for you after you finish, and the awesome celebratory atmosphere that you’ve come to expect from the Quicksilver Running Club.

The Quicksilver 100K race is a Western States 100 Mile Endurance Run qualifier as well as a UTMB qualifier (4 pts)!

The 100K:
4:30 am start
13,000+ feet of elevation gain
Western States 100 qualifying race
17-hour time limit (16-hour time limit for Western States 100 qualification)
4 points towards qualifying for the UTMB
PA/USATF Ultra Grand Prix event

The 50K:
7:00am start
6,000+ feet of elevation gain
4:00pm cutoff at mile 22

Plus, great swag and post-race party!
