Sandman Triathlon 2026
A beach triathlon on Anglesey. A sea swim off Newborough with Snowdonia across the strait, coastal roads on the bike, and a run through the forest and dunes.
6 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Adapt my training to this course.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“A sea swim off a beach with the Snowdonia skyline behind you, in late September. Not a PB race and not trying to be, but one you will talk about.”
The race
The course
No course maps for this race. The organiser publishes no downloadable route for any leg of this race, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
A beach start and a genuine sea swim off Newborough on Anglesey, with Snowdonia across the water. One of very few British triathlons that starts on sand. Sprint swims 750m, Standard 1,500m.
93km for the Legend, not the 90km the 70.3 label implies. The Standard rides 42.3km and the Sprint 22.8km.
20km, which is shorter than a half marathon rather than longer, so this is the one Always Aim High race where the label overstates the run. Standard runs 10.2km, Sprint 5.7km.
Not yet confirmed for this edition: lap counts, elevation gain, cut-off times, water temperature, transition locations. We publish these only once they are on the official course page, so check there before you pace off anything here.
