The Rumble

March 16, 2020: Due to the Center for Disease Control’s recommendations regarding events and group size as a result of the COVID 19 virus, it is with a very heavy heart that I announce the cancellation of the 2020 Peterson Ridge Rumble. I am currently deciding exactly what steps to take next, so if you have registered, please watch your email inbox and our Facebook page,, for more information in the coming days. I am so very sorry.

This is a fun, low-key event utilizing the Peterson Ridge and Metolius-Windigo multi-use trails near Sisters, OR. Bring a great sense of adventure and you’ll enjoy it! There are two distances in the event: 40 mile and 20 mile options. Both races will start and finish at Sisters Middle School.

Please do your best to pick up your packet at FootZone, as this will help alleviate lines on race morning. The packet pickup volunteers, i.e., my parents, greatly appreciate your help with this.

FootZone, April 25, 10 a.m – 5:30 p.m.

Race Start & Finish Location

Sisters Middle School, 15200 McKenzie Highway, Sisters, Oregon.

Directions to Start: 1/2 mile west of Sisters on Hwy 242 (McKenzie Hwy), on the north side of the highway. The start is actually on the road, right at the corner of Hwy 242 and Edgington (just past the Middle School parking lot).

Parking: Please park in the two main Sisters Middle School parking lots off of Hwy 242.

Post Race

We will have a post-race feast featuring Longboard Louie’s catering with their excellent burrito bar (from full-on carnivore to full-on vegan, and everything in between), Sisters Bakery treats, and other food and drink starting about 11:30 a.m., with an awards ceremony about 12:30 p.m. for the 20 mile and about 2 p.m. for the 40 mile. All participants will be able to shower in the Sisters Middle School field house locker rooms.


Top 3 overall female and male, and top masters female and male in both races will receive some cool schwag from our sponsors.

All finishers will receive a super cool pair of stylin’ Rumble finisher’s socks. Yes, this is the sock that started the whole finisher-sock craze! Some of you may wonder, why socks instead of shirts? Well, I figure that most runners have lots and lots and lots of race shirts, many of which never get worn. I also figure that most runners go through socks pretty quickly. So I thought it would be fun to give something that runners wear-out fairly quickly, and not give something that runners tend to already have too many of. Plus, the socks are really cool (partially because they have the cool Rumble logo that was designed way back in 2003 by Bronco Billy).

Also, be sure to look for your name on the random prize-drawing table for some great stuff from our sponsors.


The Rumble simply could not happen without the support of these wonderfully supportive sponsors: FootZone (only sponsor that’s been with us all 18 years), OspreyiRunFar, Bogg’s Trail Butter, NuunGu, Run Wild AdventuresCentral Oregon Running Klub, Sisters MultisportUSDA Forest Service – Deschutes Natl. Forest – Sisters Rangers District. Please support them when you can.

The Course

The 40 mile is mostly trail with some dirt road sections. The first quarter is gentle uphill, second quarter is gentle downhill, third quarter starts with a gentle up before a couple of longish, 2-mile uphill grinders, and the final quarter is gentle downhill (with some sweet views!), making for a fast finish. Mud and snowy sections are possible.

In the 40 miler, racers will run up the trail for the first mile like normal, then upon reaching the dirt road (Brooks-Scanlon and Edgington), instead of turning left like in the past, you will turn right on the road and loop back to the start line via Edgington (please run on the right). Going through the start area would be a good place to drop jackets, hats, gloves, etc. You will then run up the trail again, and when you reach the dirt road this time (Brooks-Scanlon and Edgington), you will then turn left like years past. Distance to the first aid station is 7.1 miles.

The 20 mile is gentle uphill for the first half, and gentle downhill for the second half. Upon reaching the ridge, there are beautiful views of many of the Central Oregon Cascades peaks. The 20 mile start remains unchanged.

Total ascent and descent for the 40 miler is about 3,000′, and for the 20 miler is about 2,000′.

Aid Stations and Drop Bags

There will be 6 full aid stations in the 40 mile (plus one water-only), and 4 aid stations in the 20 mile, located approximately every 3-7 miles. For the 40 mile, you can leave drop bags for AS 3 (water only) and AS 6 at the start line on race morning. Aid stations will serve water, Nuun, cola, gels, fruit, potatoes, candy, chips, etc.

Note for 40 milers: Aid Stations 3, 6, & 7 will be cupless, so…bring your own drinking container.

40 mile cut-offs

At approximately mile 24, where the 40 milers turn off the long, straight road to run their second big loop, you need to be there by 12:45 p.m. That is 4 hours and 45 min. for regular starters and 5 hours and 45 min. for early starters. If you are a 40 miler and arrive there after 12:45 p.m., volunteers will direct you straight to the finish with the 20 milers. If you get there before 12:45 p.m., you will be directed to the 40 mile loop. Aid Station 6 will have a 2:15 p.m. cutoff. Aid Station 7 will have a 3:45 p.m. cutoff.

Absolute finish cutoff for 40 miler will be 5 p.m. This is a 15 min/mi average for 40 mile early starters. Please realize this is for the benefit of the many Rumble volunteers so they aren’t out there longer than what is reasonable. Thank you for your understanding on this.

20 mile cut-offs

AS 2, 11:30 a.m.; AS 3, 1 p.m.; AS 4, 2:15 p.m.; Finish 4 p.m. If you arrive at any of these aid stations after the corresponding time, arrangements will be made to drive you back to the finish area. Thank you for your understanding on this.

40 Mile Crew Directions

Start to AS 1 (also AS 5):
Go east on McKenzie Hwy towards Sisters. Turn right at the “T” onto Cascade Ave. Turn right on Elm (Three Creeks Rd). Go about 2 miles to FS 4606, turn left. NOTE: THERE IS A GOOD CHANCE THAT RUNNERS WILL BE ON THIS ROAD – USE EXTREME CAUTION!! Drive about 1 mile (1/4 mile past where the runners turn rt). Just past the big filled-in “pit” on the right, turn right and follow this road to AS 1. AS 1 to AS 2 (also AS 4):
Retrace your route back to Three Creeks Rd. Turn left. Drive about 2 miles to FS 1608, turn left. Follow 1608 (stay right at the first left curve) up a short, steep hill. You’ll then cross the race route just before FS 500. This is the aid station. AS 2 to AS 3:
Retrace your route back to Three Creeks Rd. Turn left. Drive a little over 2 miles; just past the top of the steep hill on the left, the race course trail comes to the road. This is the aid station (FS Road 442 is on the right side of the road). AS 3 to AS 4:
Retrace your steps from AS 3 to AS 2/4. AS 4 to AS 5: 
Retrace your steps from AS 4 to AS 1. AS 6: 
Do NOT go to this aid station, as the runners will be running on this road!! I’m not going to disqualify any runners if crews drive there, but it’s kind of a jerky thing to do and we don’t want any jerks at the Rumble. AS 7: 
From the start/finish, go west on McKenzie Hwy / Hwy 242 about 1/2 mile. Turn left on Pole Creek Rd/FS 15. Drive approx. 2.5 miles to FS 100, turn left. Drive another 1/4 mile and you’re at the Cow Camp Aid Station.
