The event in a few words

Lisbon, city of seven hills, azulejos, and fado… But also, for one weekend, the playground of a 100% nature and 200% challenge marathon! 🔥 Here, it’s not just about a little jog along the Tagus admiring the yellow trams. No, no, no. We take you in April to the largest green lung of the capital, the Parque Florestal de Monsanto

Your calves will soon realize that Lisbon is all about climbing. And descending. And climbing again 🥵. The start and finish are set at Parque Eduardo VII, the largest park in the city center 🌳. On one side, a panoramic view of Lisbon, on the other, a promise: a course as breathtaking as it is challenging 😬. Here, no traffic jams, no red lights, just you, nature, and an elevation that'll test your love for running. If you've ticked the marathon box, prepare for a 42 km of character 🇵🇹. With 1,360 mD+, it’s not just a leisurely city tour, but a true wild escape into Monsanto, the "lung" of the capital. And then, finishing at Parque Eduardo VII, with the city as a backdrop, it’s quite stylish, isn’t it? For thrill-seekers, the semi-marathon is a gem ⭐️. 21 km, 740 mD+, and a perfect alternation between climbs, descents, and long rolling sections. If you’re the kind who prefers short distances over long speeches, then the 12 km is your ally 💨. Here, there's no time to dawdle: 470 mD+, some climbs that wake you up ⚡️, descents that set you free 😮‍💨, and a finish line where you can proudly say that yes, you too conquered Monsanto 🏅 (and no, not the multinational, though it’s equally noble 🙃). For those who prefer to take the time to admire the beauty of the landscape without ending up drenched in sweat, the walk of 8 km is the perfect alternative 🌿. With 320 mD+, it’s a walk well-deserved, offering exceptional views of the city and its surroundings 😎. Plus, it gives you time to scout the best pastelarias to stop by afterward. Because, well, walking works up an appetite too...🫣

You've climbed, sweated, puffed like an old Electrico 28 tram, it's time to reward yourself like a true Lisboeta 👏. Head to Belém, where a never-ending line will lead you to the ultimate grail: a pastel de nata crispy and still warm 💛. To celebrate properly, a glass of vinho verde is a must, fresh and sparkling, to revive your tired legs (to be consumed in moderation, of course 🍷). If you want to play the tourist post-marathon, head to Alfama, with its narrow streets where the climbs will remind you that there was still some juice left in your thighs 💥. Stop by the Belém Tower, take a cliché photo in front of the Jerónimos Monastery 📸, and if your legs truly give out, hop in a tuk-tuk for an express VIP-style tour 🚖.

So, are you ready to trade asphalt for trails and make your calves sing louder than a Barcelos rooster ? 🐓

4 reasons to join this race

Run in the heart of nature… right in Lisbon 📍
Lisbon is much more than cobblestone streets and yellow trams climbing improbable hills 😎. Here, you'll swap the scorching asphalt for the shaded trails of Parque Florestal de Monsanto, the largest green space in the city. It’s a marathon where you breathe deeply (and where you almost forget the climbs, well... almost 😏).
Because there is surely a distance for you 🫵
This race is for everyone, whether you're a seasoned athlete or a casual runner 🏆. There's a course for every level: a marathon for the most experienced 🏃‍♂️, a semi-marathon for those seeking a more manageable challenge 💪, and a 12 km for those looking to run at their own pace 🏃‍♀️. The stunning landscapes 🌳 and festive atmosphere 🎉 will make every step an unforgettable adventure, no matter your distance 🌿.
An eco-friendly and supportive race 🌱
No way we're leaving tons of waste behind! ♻️ This marathon is designed to minimize its environmental impact: less plastic, more respect for nature, and an organization that ensures your only trace is the imprint of your sneakers on the trails! 👣
For the Portuguese culture 🇵🇹
Let’s be honest, one of the best reasons to run here is what's waiting for you after the finish line 🤤. Because Lisbon is also a gourmet capital! You've earned it, so go enjoy a good bacalhau à brás (the famous codfish with eggs and matchstick fries) 🐟, follow with a well-goldened pastel de nata, and to top it off, toast with a Ginjinha or a nice glass of Vinho Verde 🍷.
