Your day in Palermo
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 Palermo could look like.
The course behind your race
The highway is a temptation, not an instruction.
The October 2026 course put the swim in Palermo's Lago de Regatas, the ride on wide city roads and the run through Bosques de Palermo. A road without many natural brakes is a place to practise your own. Keep a little energy for the park paths, even when the bike split looks inviting.
Buenos Aires highways, early bike
Set a ceiling before the road opens up
With no hills to force pacing discipline, it's easy to override on this flat highway loop. Hold your number regardless of how easy it feels.
Cap opening effort. Fuel early.
Buenos Aires avenues, later bike
Resist defending a faster-than-planned split
Repeat the first loop's effort and finish planned nutrition before the city run.
Stay patient. Finish planned nutrition.
Bosques de Palermo, opening run
Let park rhythm arrive naturally
Let the Palermo streets feel easy, not fast.
Easy first aid station. Check posture.
Bosques de Palermo, closing run
Use the final park kilometres to finish well
Only progress once the first half has held together.
Stay tall. Choose the last move late.
What to check in race week
The October 2026 race has already taken place. For any later edition, confirm a new date and fresh Palermo swim, road closure and Bosques de Palermo run maps before making travel or pacing plans. Find the actual aid and transition locations rather than borrowing city traffic notices from the past race.

Prepare for Palermo
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: an economical city-lake swim and controlled road speed feed a half marathon that can be run with purpose rather than survived.
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 Palermo.
