Your day in Cascais
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 Cascais could look like.
The course behind your race
Guincho, the natural park and the Estoril circuit give you plenty to look at. The useful comparison on the repeat is your effort and fuelling, with a marathon still ahead.
Praia da Ribeira · swim and T1
A single loop stays inside the protected bay, but a 600 m approach to transition with a steep opening section follows immediately. Settle into rhythm and don't empty the tank before the climb.
Settle by 400 m. Save legs for the climb to T1.
Guincho and the natural park · bike loop one
The route along Guincho Beach and through the Sintra-Cascais Natural Park is exposed to Atlantic wind. This lap repeats, so hold a power ceiling you can sustain twice.
Cap power in exposed sections. Fuel on the sheltered stretches.
The coastal route again · bike loop two
The second loop repeats the same exposed coastline and the Estoril Formula 1 Circuit lap. Ride to the same power ceiling rather than fighting the wind for a speed target.
Compare effort to lap one. Finish planned nutrition before T2.
Cabo Raso coast road · run loop one
The three-loop run repeats the exposed coastal road to Cabo Raso that the bike already tested. Start conservatively rather than fighting the wind at pace.
Shorten stride into any headwind. Hold opening pace regardless of the marina crowd.
The coast road again · run loop two
Passing Cabo Raso a second time gives a clear read on how the bike's wind exposure is showing up in your legs.
Compare loop two to loop one. Keep taking aid on schedule.
Returning to Cascais · final run loop
The final loop finishes through the crowds at Marina de Cascais. If both bike loops and the wind were respected rather than fought, this is where it pays off.
Decide the finish honestly. Save something for the marina crowd.
Once the 2027 athlete guide is published, confirm the transition location, swim exit and course loops before planning bags or pacing. Check forecast wind on any exposed coastal sections shown on the final map.
A race-day forecast is not meaningful yet; check back closer to the event.

Make your finish prediction and I can send this plan to you in race week.
Prepare for Cascais
A finish range gives you something to work towards. The preparation is specific to this race: Training has to make two long bike loops repeatable while leaving the fuelling and running durability for three coastal marathon loops.
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 Cascais.
