Quicksilver Endurance Runs - 100k & 50k

The 2021 Quicksilver 100K AND 50K Endurance Runs are planned for Saturday, May 8, 2021

The 2021 QSER Runner's Guide is in the works. Click HERE to check the previous web version or HERE for the PDF version. 

REGISTRATION OPENED IN JANUARY 2021

The 2020 race was cancelled due to COVID-19: 2020 registered runners had priority to register on Ultrasignup between Jan 10 and Jan 16, 2021. General registrations opened on Jan 17, 2021 and we have a waitlist. Due to COVID-19, we are still waiting to hear back from our permitting agencies about our permits and the number of runners we can have. Thanks for your patience.

The two courses will be the same that we've used since 2016. We will take extra measures to ensure the safety of the runners and volunteers as COVID-19 will likely still be around. 

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! (well, the party will resume after Covid...)
