Craggy Island Triathlon

Unique in the UK and probably the World, the Craggy Island Triathlon will have you swimming across the sound of Kerrera from the mainland to an island to start your race. How cool is that?


2nd – 3rd October 2021

2nd – 3rd October 2021

The award winning Craggy Island Triathlon takes place on the incredible unspoilt Hebridean island of Kerrera, off Scotland’s stunning West coast, and close to the bustling town of Oban.

The race is entirely off-road (there are no roads on the island, so there’s not much choice about that!), and will take you from sea level to the highest point of the island with spectacular views across the Firth of Lorne and Sound of Mull.

The race will provide a warm (well, we can’t promise the water will be warm!) and welcome environment for newbies and triathlon beginners, as well as a tough off-road challenge for those who fancy their chances at the head of the field.

Craggy Island 2021 is supporting the new Kerrera School House Community project aiming to restore the islands’ old schoolhouse to become the islands first community hub providing a space for islanders to socialise and hold community events for the first time.  Head over to Isle of Kerrera ( to find out more and see how you can support them.

The course

550m Open Water Swim

  • Wetsuits compulsory. A to B Swim (i.e.Gallanach on the Mainland to the Isle of Kerrera. Deep water start.

14km (ish) Off-Road Mountain Bike.

This will be on a combination of landrover and quad tracks and paths, and is a bit hilly (ahem!). There’s nothing wildly extreme, however, this is proper mountain biking in places, not just riding round a lovely grassy field – if you feel the need to walk a bit, no problem, we’d prefer you stay in one piece!. One lap. You’ll see most of the island on your travels, and have what must surely be the most scenic triathlon bike course in the world. Amazing.

MTB Course Description – Adult Race

MTB Course Description – Junior Race

8km (ish) Off-Road Run

This is going to be interesting. It’s proper off road. In fact, it’s more like a hill-race than the ‘cross country’ you might remember from school. The route will take you across rough trackless boggy and wild hillsides, but you’ll be rewarded with the most incredible views of the island, the Forth of Lorne, and the Isle of Mull. Along the way you’ll visit the highest point on Kerrera – 189m above sea level, and the ruined Gylen Castle before returning to the finish at the ferry slip. You may wish to incorporate a few hills in your training regime……


Normal Triathlon Scotland rules will apply – see for further details.

We are really hot on no littering. We rely on the goodwill of our landowners, and we just cannot afford for them to be irritated, or the island spoilt by our litter. This specifically includes Gel/Bar wrappers, Banana skins etc. Simple rule: if you’re caught littering, it’s an instant DQ. You’ve been warned (sorry to be heavy, but…. you know!).

Note: no campervans/motorhomes (vans under 6m/Transit van size are ok) are allowed in our car parks (including Puffin Dive Centre)
