The event in a few words

Rome - Ostia… The crowd goes wild before the start! The excitement in the Italian capital 🇮🇹 is palpable! Football ⚽️? No, today we're not talking about the beautiful game but about running, specifically the Rome-Ostia Half Marathon! 🏃‍♂️

Rome - Ostia… It's not just another Roman derby ⚔️, but a half marathon! 🏃‍♂️ Starting from the EUR district in Rome and finishing by the seaside in Ostia resort, this 21km race is held every March, for over 50 years now! What a way to kick off your road racing season with optimal conditions! Expect dry and mild weather 🌤️. In the Latium region, it's almost always sunny! ☀️ Che bel sole as they say in Italiano, with that melodious accent of your favourite pizza chef ("what beautiful sunshine", in case you skipped Italian in school 😉). Plus, the course is quite flat, perfect for potentially setting a new personal record! 🕦 In fact, the Roma-Ostia is the fastest Italian half marathon in history 🚀, with no fewer than 6 runners finishing in under an hour 🤯. And in 2022, the second best global time of the year was recorded between Rome and Ostia. Talk about a half marathon to remember 😮.

Uno, due, tre… Let's go! Your race will start in the EUR district, south of Rome 📍. Less known to tourists, this area created by Mussolini is rich in history 🏛️. Mussolini intended this place to showcase fascist ideology, including modern and futuristic buildings and green spaces🌳, all connected to downtown by the Via Cristoforo Colombo. And it's this very avenue you'll take for 17 km, not heading into Rome's center, but running to Ostia, the nearest beach resort to the Eternal City. Crossing the finish line, you'll be greeted by the sea 💦! Considering a quick dip? Unless you're up for some cryotherapy 🥶, we don't recommend it, the water's at 14°C… Remember, it's March! 😬

Sights, sea views… It almost sounds like a sightseeing tour! But make no mistake, the Rome Half Marathon is also a real sporting challenge 💪! For evidence, some of the world's greatest athletes have run this half marathon! 🏆 British athlete, Stephen Henry Jones, known for running the Chicago Marathon in just 2 h 8 min 05 s (world record in 1984), has participated in the Rome Half Marathon! So, ready to set records following the footsteps of champions? 😜

So, what's next after all that? 🤔 If you're already familiar with Rome, then Ostia is where you should head next 🧳! Just 30 km away from Rome's center, Ostia is Rome's go-to seaside resort! 💧 Sunbathing might be challenging in March 🏖️, but Ostia is lively! 🥳 You could visit the Ostia Theater 🎭. Built during the reign of Augustus, at the end of the 1st century BC, this theater could host up to 2,500 spectators for a variety of shows! To fully enjoy the dolce vita, consider renting a Vespa 🛵 and exploring the village of Torvaianica with its fine sand beaches and dunes! And (saving the best for last 😋) you can also savor the specialties of Latium in Ostia's many restaurants 🤤. Pasta alla Zozzona, Gnocchi alla Romana 🍽️ or the classic pizzas 🍕, all accompanied by a refreshing Spritz on a terrace... 🍹 What more could anyone ask for?

So don't forget your running shoes 👟 and your best Italian accent (pro tip: Listen to Umberti Tozzi's "Ti Amo" again and again)… And get ready for an amazing race! 😎
