IRONMAN 70.3 Poreč.
Your best day in Poreč.
Poreč is the sort of place that makes racing the Adriatic coast feel like a holiday, until you try to run well off a 90 km bike. Spend your energy carefully on the Istrian roads and you'll have something left to enjoy by the sea.

Your day in Poreč
What could you race?
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Poreč could look like.
The course behind your race
Make the run the best part of the coast.
A sea swim opens the middle-distance race before a ride through Istria and a coastal half marathon. The full bike profile and exact run turns still need the final course map, so don't invent either a flat time trial or a mountain stage. Choose a flexible effort that can handle both.
Istrian countryside, first bike stage pending
Choose an effort you can hold if the roads roll
A course built for fast times still rewards a disciplined watt number over chasing the pace around you.
Watch the watts, not the speed. Fuel early.
Istrian coastal return, map still pending
Keep fuelling and pace independent of the scenery
Use the closed highway section to hold effort and finish your nutrition before a rolling run.
Stay aero. Finish planned nutrition.
Poreč coastal run, opening section pending
Make the first kilometres comfortable
Let the run out toward the city centre feel easy, not fast.
Easy first aid station. Check posture.
Poreč event finish, precise location pending
Raise the effort only if you can finish well
Only progress once the outbound half has held together.
Stay tall. Choose the last move late.
What to check in race week
Confirm the 2026 swim beach and buoys, Istrian bike turns, half-marathon loops and aid. Get the actual elevation and transition locations from the final map rather than guessing from descriptions of a fast race.

Prepare for Poreč
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: a calm Adriatic swim and measured bike effort are rehearsed so that unknown local roads don't make the half marathon unnecessarily hard.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Poreč.
