As the ferry pulls away from Ardrossan you leave regular life behind. Anticipation builds throughout the hour-long, scenic ferry ride, as jagged peaks come into view, and finally the ferry unloads in Brodick, on the Isle of Arran.

The Isle of Arran is known as “Scotland in Miniature,” with more than 60 miles of rugged coastline, atmospheric woodland, soaring peaks, historic ruins and trails aplenty. Arran is quickly becoming one of the UK’s must ride destinations, with trails ranging from steep and technical to fast and flowing. In other words, it’s the perfect location to host the Grinduro.

Grinduro Scotland will be based in the village of Lamlash in a beautiful sheltered bay that overlooks the impressive Holy Island. This is where it all happens, from the Bike and Art Gallery to the post-race music festival and party. This is also where the route departs from, heading out on a mix of forest roads and singletrack trails that offer expansive vistas along the way. After a return to the event village for lunch, the afternoon loop heads north, offering more singletrack and a visit to the grounds of Brodick Castle. Some testing climbs give more amazing views, before descending a cliff top trail to the finish.

THE BEST BIKE: You can ride any type of pedal-driven bicycle (no electric-pedal assist!), although we recommend a cyclocross bike or mountain bike. The ultimate setup is probably a disc brake-equipped cyclocross bike with fast-rolling, tubeless clincher tires. Be prepared with at least two extra tubes, a multi-tool and mini-pump.

We’ll be in Scotland, so rain should be expected. Be prepared with a rain shell and the basics—ideally arm/leg warmers too—just in case weather rolls in.

There will be feed zones (and an excellent lunch!), but smart riders will bring at least two water bottles and their favorite nutritional supplies.

We recommend mountain bike pedals and shoes for their versatility.


And don’t take the start line without a helmet on!

This event combines the best attributes of gravel road races with the best parts of mountain bike-style enduros. It’s a 83.3km loop of pavement and dirt, where finishing times aren’t based on overall loop time, but four timed segments.

Special Stage 1, Fireroad of Fury – 4km to 6.5km

Flat out, high speed forest road descent … early on in the day coming up directly after a long climb this is your time to shine early!  HAMMER TIME!

Special Stage 2, The Lung Buster – 18km to 20.8km

At the most northerly part of the course you will encounter a lung buster of a stage.  Mixed gradient and track you need to muster all you can to win over this climbing stage.

Special Stage 3, Lunch Roll  – 42km to 47.5km

No joke this is a long one, the longest stage of the day comes after lunch.  A rolling fireroad assault with not enough down to recover and enough up to bring on those burning legs.  Don’t quit and go all in!

 Special Stage 4, The Final Fling – 78km to 81.2km

The final tester, a descent of singletrack track testing your bike handling before fortune favours the brave in the fireroad finale.  Leave it all on the trail!

* Timed Segments may be subject to change


Be cool, have fun and enjoy the ride. Those are the rules! For those of you who need things spelled-out, here you have it…

The Terms and Conditions detailed below apply to all entrants participating in the Grinduro. Completion of an entry form or purchase of an entry by every participant acknowledges acceptance of these Terms and Conditions by the participant.

  • Riders are required to attend a start line briefing and read briefing notes and sign to confirm that they agree to abide by the instructions given.
  • All riders must be self-supported. The event organizers and staff are not responsible for your preparedness while riding the course.
  • You should ensure that both yourself and your bike are in a serviceable state to complete a 60-mile mixed-terrain ride. A standard road bike is NOT suitable for this event.
  • Each participant, upon signing the registration form, agrees that they are physically and mentally capable of riding the distance they have chosen. If, during the event, they decide to change their route and distance, then all consequences of this action are theirs.
  • If the situation arises that you are in an accident and are not capable of making the decision to call the emergency services, the rider agrees that a member of the organization or a member of the public/other rider may call for them.
  • At any time pre, during, and post event, riders must conduct themselves in a manner that does not discredit themselves or the event organizers. Riders must be considerate to other users of bridleways, tracks, byways and public ways when riding on and off road.
  • Riders are expected to respect the countryside that the event travels through. It should be remembered that this is both a working landscape and home to many communities. Riders stopping for a comfort break are asked to do so discretely and appropriately and not to cause any offense to local residents or other riders.
  • There may be sections of public road included within the course. You must obey all Highway Code rules.
  • Riders whilst participating in the event must do so wearing a helmet complying with latest EN1078, ANSI Z90/4 or SNELL standards. Any rider not conforming with this term will not be allowed to start or will be removed from the event if started.
  • Riders must carry the minimum required equipment for the full duration of the course. Spot checks may be used to ensure rider safety.
  • The organizers reserve the right to postpone or cancel the event should access to the event or sufficient portions of the course be deemed too dangerous due to severe adverse weather conditions.

  • Organizers cannot take responsibility for loss or damage of personal possessions during the event.
  • During the event there will be warning signs at appropriate points on the trails or roads used for this event. Absence of these signs does not signal there are no dangers approaching and it is the individual rider’s responsibility to make a decision regarding whether to ride a section or not. The marking of the route does not necessarily indicate that the trail or road is rideable and the participant is deemed to make their own decision about whether to proceed on bike, foot or not at all.
  • Riders are expected not to drop or leave any litter on any part of the route and to dispose of it responsibly at an appropriate place or bin. Any rider found littering will be disqualified from the event.

  • In the event that a participant fails to complete the course for any reason they agree to return to or call the event centre before the close of the event and report to a member of staff. Not doing so will mean that a search may be organized and the subsequent cost will be billed to the rider.
  • Entries are NOT refundable, but transfers are possible up to 2 weeks prior to event through Results Base where you purchased your entry.
  • An acceptable charge for any loss or damage caused by a rider to timing equipment will be made.
