How it works

This isn't a traditional cross-country run. It combines running with scrambling, and maybe even a little parkour. Then you douse it all with adrenaline.

Your goal is to make it across the rocks, to the far side and back. Historically, this was first done by Sid Choquette in order to warn an oncoming train, but you're doing it to get the best time. You start from the Frank Slide Interpretive Centre, and run counterclockwise for approximately 1km on the interpretive trail to the first Checkpoint. At CP1 you dive into the Frank Slide. There is no set route through the rocks, so you need to pick the best line. The Slide isn't flat either; it rolls like waves, so you need to keep your head up and get to high ground in order to see the next CP. Straight lines may not work out for you since the terrain is so varied, with some boulders the size of buses. Depending on your route, the course is approximately 5km, including the run at the start. The elevation depends on your approach but your heart rate will be way up there. It will be interesting to compare Strava afterward!

In order to minimize congestion on the singletrack, and when entering the rocks, you will start in heats of 20 racers every five minutes. Heats will be confirmed one week before the race, but the intention is to go by bib numbers (1-20, 21-30, etc.).

Each CP has a tall flag and a bag of coins; you must take a coin to prove you were there. You follow blue flags when heading out, and red flags when coming back. You have to reach each CP in numerical order. Once you reach CP7, you follow the trail back to the Centre and the finish line. The start and finish are recorded digitally.

While there is no set route through the Slide, the map below shows a point-to-point description. Blue lines lead you away from the Start, red lines lead you back to the Finish.

Recommended Gear:

Prohibited Gear:



Let's not mince words – there is a lot that can happen to you out there. You are the best person to keep yourself from injury; you do that by being aware and prepared. The two most common risks are a trip resulting in a fall, and a rock tipping you off. Both can result in a break or other injury. Like anywhere in the mountains, there is also a chance of animal encounters on the first run section, but it is highly unlikely that you will see large animals once you get into the rocks.

Here are the best ways to prevent injury:

Your heart will still be pounding, even if you slow down, so think through each step. Race smart!


What's Included

Besides the adrenaline rush and glory, here is what you can look forward to:

The top female and male competitors will get what Sid received for running the rocks back in 1903: a certificate of commendation and a cheque for $25. (actually, you'll get more than that so stay tuned)

We ask that all racers park down the road in the forest reserve and walk up to the site (about 500m). Watch for parking signs on the access road.

We will have a shuttle vehicle if you need a ride, but don't count on it if you're in a hurry!

Take a look at the site map - it shows parking and the start location.
