Quicksilver Endurance Runs - 100k & 50k

The 2021 Quicksilver 100K AND 50K Endurance Runs are planned for Oct 23, 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. 

Due to COVID-19 and permitting issues, we unfortunately had to cancel both the 50K and 100K races planned for 5/8/21 (again!). We were to secure permits for the race on October 23rd, 2021.

The two courses will be the same that we've used since 2016, except that we will finish at Hacienda instead of Mockingbird.

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 (although likely simpler this year).
