Challenge Gdańsk 2027
A 100-distance triathlon at Gdańsk: a Baltic Sea swim, a flat 80 km bike loop and a four-lap run by the beach and Reagan Park.
37 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? T100 training support cover 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 organiser describes a flat single-loop bike and a four-lap run by the beach, so even pacing and fuelling matter most.”
