Start time 2:00 am on Saturday, July 18th, 2020
The final cut-off is 16 hours (6:00 pm on Saturday)

*Prerequisites: Possessing a healthy appetite for beauty and pain... No "race" prerequisites but this is NOT your grandma's 50-miler... Be prepared for a TOUGH race that many have described as the most difficult 50-miler they have ever done, but their favorite!

Start & Finish at Big Elk Creek YMCA camp located here, the course covers 1 GIANT, 51-mile figure-eight
- 97% Single Track (zero asphalt, only a few miles of dirt road)
Cut-offs: There are only 2:
- N. Indian Cr., the final time, leaving by 11:00 am Saturday morning
- Big Elk Creek finish, 6:00 pm Saturday evening
Creek Crossings, there are multiple ones, depending on snowmelt, but none of them are over thigh-deep with the deepest being Big Elk Cr. and a rope is secured during high water years
- You will have wet feet, you will NEED merino wool socks and shoes that drain well
- We discourage the use of waterproof shoes as they won't breathe well in the July heat
Drop Bag and Crew/Spectator Access at miles 9.5 and 30, both at N. Indian Cr. located here
Wilderness Aid Stations located at miles 14, 23, 34, 42, 45 for a total of 6 fully-stocked wilderness aid station stops (8 total)
- Medical personnel will be staffed at most of these locations and have In-Reach GPS units to text back to the medical director
- Liquid IV's will not be available
Filtering Water: We do not recommend drinking from any of the streams without using a water filter. There are multiple points to filter water if needed, except for 2 major stretches:
- Quaker Flat/Blowout Canyon has lots of climbing, exposure, and the only possibility of water access being along Spring Run (closer to N. Indian Cr.)
- Dry Canyon is a long dry stretch after leaving Garden Gnome aid station late in the race, so stock up well
  - A couple of miles up Garden Canyon there is a possibility of water access before the canyon turns to the west, this a good place to filter water and top yourself off before your last grueling climb late in the race
NO PACERS allowed in the Grizzly 50
Pricing: $175 by 12/31/19 - $200 by 3/31/20 - $225 until registration closes July 4th, 2020
