Nestled along the sun-kissed shores of Andalusia, between Malaga and Gibraltar, lies the picturesque city of Marbella. Known for its charming seaside ambiance, this vibrant resort town invites runners to experience an unforgettable half marathon or a scenic 5 km run during late September. As you lace up your shoes and step onto the starting line at the Sierra Blanca Estates Marbella Half Marathon (officially known as "RUN-On"), prepare yourself for a race that promises stunning Mediterranean views. The flat course winds alongside the sparkling blue waters, offering runners an opportunity to push their limits and chase personal bests. For those who prefer team camaraderie over solo efforts, relay teams are welcome in this event. Whether you're running alone or with friends, the city’s warm climate will ensure a comfortable run even as autumn begins elsewhere. The race route takes participants through Marbella's picturesque streets, past luxurious villas and yachts dotting the coastline, and along stretches where the deep blue sea meets golden sands. The scenery is nothing short of breathtaking, making it hard to know which direction to look first. After crossing the finish line, immerse yourself in Andalusian culture by exploring Marbella's historic landmarks. Visit the Church of Our Lady of the Incarnation or admire the iconic silhouette of the Marbella Building against a backdrop of azure skies and sea. Stroll along medieval walls that once enclosed the ancient Arab medina and delve into history at the Mosque of King Abdul Aziz, also known as the Great Mosque of Marbella. If you're eager to explore further, consider extending your stay in Granada or relaxing on terraces in Malaga while enjoying authentic tapas. The region offers a rich tapestry of experiences that complement the race's vibrant atmosphere perfectly. Join us at the Sierra Blanca Estates Marbella Half Marathon and let yourself be charmed by this delightful coastal city where every step feels like an adventure.
