Snowman Triathlon 2027
The toughest of the Welsh adventure triathlons. A mountain lake swim, a climbing bike leg, and a run that heads up into the Snowdonia peaks.
49 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
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.
Build my complete road.
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.
“The run goes up a mountain. That is not a figure of speech. If you want to know what you are actually made of, this is the British race that tells you.”
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 mountain lake swim in Snowdonia, cold enough that the wetsuit is not the question, the first two minutes are. Sprint swims 750m, Standard 1,500m.
95.6km for the Legend, the longest of the three Always Aim High bike legs and five and a half kilometres beyond a nominal 90. The Standard is 69.1km, which is unusually long for a standard-distance race, and the Sprint 27.1km.
21.2km through the mountains. The Standard run is only 8.7km against a 69.1km bike, so that option is far more of a cycling race than its name suggests.
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.
