Event overview
Take in all of the sights that the north of the island has to offer!
With a new swim and run course and a slightly altered bike course, the event will once again take place across two days with the choice of racing on Saturday or Sunday.

The course will see you swim 600m point-to-point around the pretty Kerrera Marina, before heading off to Gylen Castle at the South end of the Island on the 16km bike course. Once back at the Marina you will head out for a beautiful 8.5km trail run around the North End peninsula with views towards Dunollie Castle.
The races are off-road, and will take you around the island's coast and over the wild hillside terrain with spectacular views across the Firth of Lorne and Sound of Mull.
This event is part of Craggy Island Triathlon.

Event venue
Kerrera Marina
Isle of Kerrera,
Oban
PA34 4SX
Using the north of the island means you can get the event foot passenger ferry directly from Oban, avoiding a previous logistical issue with narrow roads, a lack of near-by parking facilities, and people getting to and from the start line.
Not only that, there are now much better services and a better event experience.
Kerrera Marina is home to the Waypoint Restaurant and Bar which will be serving up delicious refreshments throughout the event – or even a beer for your supporters – and possibly even you after the race!
You’ll find regular toilets, shelter, and hard standing – simple things that bring a little more comfort. Finally, this venue means that the event date won’t be determined by the tide.

Swim
Open water swim.

Deep water start.
Water temperatures vary depending on the weather conditions pre-event but the sea temperature is likely to be around 12-14oC.

Bike
Off-road mountain bike.
This will be on a combination of Land Rover 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. 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.

Run
Approx. 8.5km off-road.
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, across to the Isle of Mull. Along the way you’ll visit the Hutchesons monument with stunning views across to Dunollie Castle, before returning to the finish at the ferry slip. You may wish to incorporate a few hills in your training regime...

- Sustainability policy
This event is trying to raise its sustainability game. Yes, it's small stuff, but it's a start, and every bit helps. There are two main changes:
Cups
Feed station cups are this event's biggest source of waste so it is completely stopping the use of them. There will be no cups at feed stations. You will need to bring your own hydration system, whether this is a camel back, hydration vest, soft bottle or simply bring your own collapsible cup, carry this with you and it can be topped up at the feed stations.
T-shirts
Many of you love and use them, however, some of them get disposed of without ever getting used. So, when you enter you will have the option to choose "No T-Shirt". The cost of your entry will remain the same, and the equivalent of the cost of your T-Shirt will be donated to the selected charity.
