The water sits at 16°C. You wade into the Bay of Cascais, pull your wetsuit tight, and take your first stroke. The Atlantic is cold and honest. That is how most mornings start here.
I'm Tomo Greer. I'm a triathlete and coach, and I once placed in the top 20 of my age group at the Ironman World Championship. For seven days in Portugal, you'll join a small team on the coast at Cascais, with the beach on one side and the Sintra hills on the other. This is a hard trip. I will not pretend it isn't.
We ride the Sintra loop, climbing past Malveira da Serra and dropping to Colares. One day is 80 km with 1,000 m of climbing. We swim open water at Praia da Duquesa and work on sighting in a group. We run the real Ironman Cascais course, past Boca do Inferno, undulating out and back. A support van follows every ride with drinks and tools.
There is rest in it too. We hike up to Palácio da Pena, the highest point around, with views to Lisbon. We eat together each night, from a spot by the Casino Gardens to a small place in Azoia. If you stay for the Ultra days, we ride the full bike route to Lisbon and drill your T1 and T2 until they feel easy.
By the last climb, your legs will ache and the sea will be right there below you, bright and endless.
I'll take you through it.
Tomo is on the same climb as you every day — out front, firing you up, and getting the group through the difficult bits together.
Difficult on purpose.
These days are meant to be difficult. They're the ones you talk about for years — and you get through them together.
Apply to join the team.
We pick the team carefully — attitude and fitness both matter — so everyone on the mountain belongs there and is ready for the difficult days.
The moment
Day five. We finish the forest run and reach the top of the Natural Park, breathing hard, legs burning. You look out over the trees to the ocean, and everyone is there, grinning, because we made it all the way together.
Before you go
This doesn't start on day one. When you join the team you get a training plan for the weeks before, coaching to get you ready, and a team space to meet the people you'll go with. By the time you arrive, you'll know you can do it.
Apply to join
We read every application. Small group — and I want to get the group right. If this sounds like you, apply below.
How the week builds
Day 1
You land in Lisbon and we drive to Cascais, just 25 minutes away. The sea sits on one side, the hills of Sintra-Cascais Natural Park on the other. We shake out the legs with an easy run along the Paredão. Then a welcome briefing and dinner at the hotel. The salt air, the first night together.
Day 2
Day 2 is a big one. We ride 55 km with 750 m of climbing on the Sintra Loop. Out to Guincho, up through Malveira da Serra and Biscaia, down to Colares, past the Estoril track. A support van follows the whole way. Later we run 10 km of the Ironman course. Boca do Inferno at your shoulder.
Day 3
Day three starts in the water. We walk to Praia da Duquesa and swim 1,500 to 2,000m in the Bay of Cascais. Wear a wetsuit; the water sits near 16°C. Then an early lunch. In the afternoon we ride 80km with 1,000m of climbing past surf beaches and quiet hills. Dinner by the Casino Gardens in Estoril.
Day 4
Day 4 starts in the water. We swim 1,500 to 2,000 metres at Praia da Duquesa, working on sighting and swimming as a group. Then we stretch on the sand. After lunch, we drive to Sintra and hike up to Palácio da Pena, the highest point around. We walk down through the forest, past old palaces, as Lisbon fades behind us.
Day 5
This is your last full day. We ride the Sintra loop in reverse, 60 km with 800 m of climbing. Back roads up, then down to Colares, then home with a tailwind. In the afternoon we run 12 km through pine and eucalyptus to a park peak. Those views are worth every step.
Day 6
Day 6 splits the group. If you're on Core, we share one last breakfast, then you transfer to Lisbon Airport. If you're staying for Ultra, you ride the full Ironman Cascais bike route. That's 90 km with 600 m of climbing, past Estoril and along the Marginal to Lisbon. The Tagus runs beside you both ways.
Day 7
Day 7 starts at Guincho Beach. We run 8 km along the shore. Easy, scenic, with the ocean right there. Finish with a dip and a drink at the café. Back at the hotel, we work T1 and T2 at the pool. Ask me anything. Then our final dinner. Salt still drying on your skin.
Day 8
Day 8 is goodbye. We share one last breakfast together as a team. The talk is easy, full of the roads and swims behind us. Then I'll see you off to Lisbon airport for your transfer home. Portugal stays with you. The hills, the sea, the quiet pride of hard work done well.
