The concept of entry to The High Rouleurs Society is simple. Pick any route, loop, or combination of roads and ride until you reach 10,000 vertical metres (32,809 feet). Although the concept is simple, we have built in a set of rules to keep everyone using the same benchmark. Everyone loves comparing apples with apples. Nothing is foolproof, but we ask for your respect with what we feel is the best approach.
It is mentioned several times below, but if you find yourself rocking yourself to sleep in a corner over the rules then simply get in contact via


There is more than one way to skin a cat

There are two ways you can rack up your 10,000m vert for your entry into the High Rouleur’s Society. Unlike everesting, there is no race to be first on a route, so get your mates to ride with you in a group, and feel free to socialise your planned route beforehand.

One single unbroken ride of more than 10,000m vertical. No time restriction, no distance requirement, no sleep allowed. THE LIMIT is all about finding the boundaries of what is possible in a single ride.

More than 10,000m vertical in less than 36 hours, with a minimum of 400km. Sleep is allowed (while the clock is ticking), and in fact it should form part of your strategy! THE JOURNEY is all about the joy of plotting something epic and unusual. With the ability to start the two days in different locations you should be getting creative with what can be achieved.

Specific rules regarding these two ways of achieving 10,000m vertical are listed below, referencing either THE LIMIT (single ride), or THE JOURNEY (36 hour limit & 400km minimum).

If you dream up the ride and it contains the required vert then we will accept it. Time to get creative.
– Routes can be any combination of cols/hills/mountains with any number of roads used
– Routes can be ridden as a loop, as a point-to-point, or of any make-up and combination of repeats
– Roads can be of any surface, or combination of surfaces.
– You can organise a bike swap to take this concept to its limits
– If you complete a traditional Everesting attempt during your 10,000m vert it will qualify for both the hall of fame, and entry into The High Rouleurs Society

Recording devices
Data integrity is the key here. We want your ride to count, and YOU want your ride to count. Data isn’t perfect, and no recording device is perfect, but we are interested in being as accurate as possible. This isn’t the forum for a GPS vs barometric debate, so if in doubt shoot a non-whinging email to
– Rides must be recorded on a device with a barometric pressure sensor
– Do not use the elevation correction option when uploading your data
– Some elements of the ride can be manually adjusted in our upload stage
– THE JOURNEY can be recorded as two separate files, and automatically merged during the upload process

Hosting your ride
We’ve created some cool visuals and in-depth data analysis in conjunction with Veloviewer. With that in mind we needed to choose one platform for all entries. Steps for hosting are simple:
If necessary complete a data merge (if merging two files)
– All rides must be uploaded to Strava (including retroactive claims. If your retroactive claim predates .FIT or similar files drop a line to If you can prove the claim we will honour it)
– Rides must then be submitted via Veloviewer

Battery life
In most cases attempts will outlast a computer battery. Plan ahead to ensure you are not caught short
– The easiest option is an external battery pack. Test it beforehand. Some devices will reset if plugged in mid-ride. An On The Go (OTG) micro-USB cable has an internal pin removed which will allow charging while you are rolling. This seems to be an issue with the Garmin Edge 500 units.
– A second option is to start a new device once the old one runs out of battery. Your files will need to be merged post-ride, and before being submitted.
– For THE JOURNEY the ride totals will be automatically calculated for you if you are uploading two files

Breaks are not only allowed, but are almost essential in completing this challenge. You’ve got to eat, stretch, change kit, and rehydrate.
– Breaks are allowed, and can be of any frequency and duration.
– During THE LIMIT single-ride attempts there is no nap/micro sleep/sleep allowed
– During THE JOURNEY you are allowed to nap/micro sleep/sleep as you see fit. Bear in mind the 36 hour clock is ticking while you are sleeping, but there should be enough time for a few hours.
– As a tip, reduce the amount of time you do break, as these add up very quickly over the duration of the ride.

THE LIMIT: The key to this challenge is completing it in one ride. We feel that sleeping (or napping or microsleeping etc.) effectively turns it into multiple rides. At what point does a microsleep become a sleep, and what is the time limit therefore on a sleep? With that in mind, and in the spirit of a ‘one ride challenge’ we specify no sleep/microsleep/napping (and any other term you might have!). Naturally no one is there to check whether your 15 minute break encluded shut-eye, and this is where your integrity comes into play. Sleeping (or any form of sleeping) is not permitted for THE LIMIT challenge.

THE JOURNEY: How you use your 36 hour allocation is completely up to you. During the 36 hours you will need to complete a minimum of 10,000m vertical, and a minimum of 400km. With good planning this should allow a good amount of time for a sleep break. It will also minimise the amount of time you need to ride at night. Your end point for day one does not have to be the starting point for day two, so get creative. You could potentially do the second day’s climbing in another country!

For both THE LIMIT and THE JOURNEY you have the ability to switch bikes during the ride. This should open things up for your creativity.

We have divided our leaderboard into a number of bike categories:
– Road
– Mountain bike
– Cyclocross
– Single speed
– Fixed speed (surely not?)
– Recumbent
– Tandem
– Mixed bikes (bike swaps i.e. using Road & MTB)
– Other
We feel this represents the core, but naturally if there is another type of bike we are missing the you have a claim for please be in contact.
– Electric or motorised bikes are obviously not accepted

Time limit
It takes a long time to knock out a minimum of 10,000m vert.
THE LIMIT: There is no time limit for completion. If you don’t sleep, you can keep going as long as you like.
THE JOURNEY: There is a 36 hour maximum, and during this time you will also need to ride a minimum of 400km.

“It only counts if you get off the mountain”
– Nothing is more important than getting back home. Remember, you are not playing for farms here, it’s about the beauty of going for a ride.
– As with any outdoor activity there are elements both in and out of your control. It is up to you to monitor both to ensure you remain safe at all times.
– Organise a support crew to join you on the day. They will be the best judge of your state, and their advice needs to be taken seriously. If they think it’s time to pull the pin they are only suggesting this with your best interests in mind.
– Tell someone your plans before you go, and check in regularly.
– Your consideration of this challenge means that you are going to explore the limits of what your body is capable of. Know your limits, know the signs of breakdown, and be prepared to walk away.
– Our strong recommendation is for both personal/medical insurance and ambulance cover (if applicable).
– Get a medical check-up before you attempt this.
– If you are under 18 years old, get a parent or guardian’s approval first. In fact, whatever age you are, ask your mum.

We’d love to watch your epics unfold. Keep us in the loop via the #highrouleur hashtag, and feel free to tag @hells500

Retroactive claims
We are all for retroactive claims for THE LIMIT rides (unfortunately we don’t accept retroactive claims for THE JOURNEY.. it’s just a little bit too difficult to administer). The easiest way to make your claim is to submit your date. If your effort pre-dates recording devices get in contact at and as long as you can provide evidence we are happy to validate the effort.
