XXI Marató del Mediterrani RACC 2026

What is the route of the XXI Marató del Mediterrani RACC 2026

The Mitja Marató del Mediterrani RACC offers one of the fastest half marathon courses in Catalonia, ideal for chasing a 21K personal best. Starting and finishing at the Canal Olímpic in Castelldefels, the route is mostly flat, combining urban sections with long stretches along the Mediterranean Sea.

The opening kilometers require caution, with a narrow start, tight turns and an early crossing of the C-31 bridge. After that, the course becomes very smooth, especially along the seafront, where runners can maintain a steady pace, although wind conditions may play a role.

The race follows a two-loop course, allowing runners to use the first lap to gauge effort and adjust pacing for the second. The main challenge is the repeated bridge crossing, which requires slight effort adjustments without breaking rhythm.

In the final kilometers, back inside the Canal Olímpic, comes the most mentally demanding section: a long loop where the finish line is in sight but still far. This is where pacing matters most, saving energy for a final push in a race designed for speed.
