Adventure Series 2024 Triathlon Sandman Legend

The final part of the Adventure Series and a fitting close - the Sandman has been described as the most beautiful triathlon in the race calendar.

The race starts and ends in one of Anglesey’s most treasured spots, the incredible Newborough Forest, an exclusive 700ha area of woodland adjacent to the world-famous Llanddwyn Beach.

One of the few Triathlons on the calendar with a beach start and sea swim, your supporters can build sandcastles and eat ice cream whilst you race!

Enter the Series and this event is 50% cheaper than if you enter it as a stand-alone race.

Llanberis, Plas y Brenin, Newborough Forest


Route Description

With a beach start and sea swim, lining up on the glorious Newborough beach is an unforgettable feeling. The route is a simple out and back but only the ocean will decide whether you're pitted against calm waters or white-tipped waves!

Don’t believe the rumours that this Island is flat! There are plenty of climbs and descents on this bike route to keep you on your toes. Starting from transition in the heart of Newborough Forest, climb up to the village of Newborough and take a right. Head round the sweeping bends and fast straights whilst also negotiating the tight village streets before turning left before the famous village of Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. You will then go onto Menai Bridge, catching a glimpse of the iconic suspension bridge before heading along the narrow coast road to Beaumaris. In Beaumaris, turn left and ride up Allt Goch; the Red Hill, a brutally steep climb before descending down to Pentraeth. Some of the roads get noticeably narrower and deserving of some respect. Pass through a number of villages including Brynteg, Rhosmeirch and Trefor continuing on towards the seaside town of Aberffraw with stunning views of the coast. Riding through Malltraeth and on towards Newborough, descend down the forest road once more and to transition ready to get your running shoes on.

Legend Triathletes complete 2 laps of the Standard run loop. With Newborough Forest once hosting the Commonwealth Mountain and Ultra Distance Running Championships it's safe to say the trails on this section are world-class. Running through trees and catching glimpses of the sea and marshland within this forest is just magical if you’re not distracted by how much your legs are now starting to hurt! We don’t make it easy either, the last 1.5km is almost entirely on sand - it makes the accomplishment of becoming a Sandman Legend all the more rewarding!
