IRONMAN 70.3 Costa Navarino, Peloponnese, Greece.
Race Navarino Bay on your terms.
Navarino Bay is an inviting place to start a race. The olive groves and pines beyond it look serene, and the Gialova lagoon offers a beautiful running backdrop. None of that removes the need to save energy for the last half marathon kilometres.

Your day in Navarino Bay
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 Navarino Bay could look like.
The course behind your race
The bay is a start. The lagoon is where patience pays.
The earlier course opens in sheltered Navarino Bay before carrying you through olive country and pine roads. Running by Gialova and Divari Lagoon looks beautiful on paper. After a hard bike, you'll notice the effort more than the scenery. Give yourself a chance to enjoy both.
Messinian olive groves, first bike stage
Hold power below the excitement of the rural road
Ride the olive groves and pine forest at your planned watts. You will see this loop again.
Watch the watts, not the speed. Fuel early.
Pine forest roads, later bike stage
Keep fuelling through the changing landscape
Resist racing riders you recognise from lap one. Match the effort, not the moment.
Stay aero. Finish planned nutrition.
Gialova and Divari Lagoon, prior run opening
Let the first kilometres feel comfortable
Let the first pass through Gialova village feel easy, not fast.
Easy first aid station. Check posture.
W Costa Navarino, previous finishing area
Make the late move only once the run is holding
Only progress once the first loop has held together.
Stay tall. Choose the last move late.
What to check in race week
The October 2026 race date is set, but the detailed Navarino swim, olive-road bike and lagoon-side run landmarks come from an earlier course description. Check the actual 2026 map, transitions, sea state and aid before using those places as lap targets.

Prepare for Navarino Bay
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: sea sighting, steady rolling rural-road effort and an unhurried lagoon-side half marathon are practised together.
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 Navarino Bay.
