Introduction. The A Coruña Half Marathon, popularly known as C21, once again placed the Galician city firmly on the national and international running map. The 2026 edition took place on 1 March and delivered a new men’s course record, thousands of participants and a festive atmosphere along the Atlantic waterfront. In this article, we look at how the race unfolded, who the key protagonists were, what makes this event special and we share practical tips for preparing your own challenge on a flat course like A Coruña’s.
History and key features of Coruña 21
For nearly three decades, Coruña 21 has brought together recreational runners and elite athletes on a 21.097-kilometre course that hugs the Atlantic coastline. The race is part of the official athletics calendar and enjoys international recognition, making it one of Spain’s benchmark half marathons. Organisers pay close attention to the layout: a flat, fast course that in 2026 started at the marina and, for the first time, finished in María Pita Square, the historic heart of the city.
In addition to the half marathon, a 5 km race was held for runners who prefer shorter distances or are just starting out. The mild early-March weather and enthusiastic local support turn C21 into a true running celebration, with cheering points, live music and volunteers lining the entire route.
2026 race report: records and standout performances
The 2026 edition will be remembered for a new men’s course record. Kenya’s Meshack Kipkurgat crossed the finish line in 1:01:10, shaving nearly half a minute off the previous best. His strategy was built on holding a steady pace of around 2:54 min/km before increasing the tempo in the closing kilometres. The men’s podium was completed by Spain’s Carlos Mayo (1:02:43) and Jesús Ramos (1:03:11), confirming the strong level of Spanish distance running.
Close to 3,000 runners started the half marathon and around 2,600 reached the finish line, highlighting the event’s growing popularity. In the women’s race, Venezuela’s Edymar Brea claimed victory in 1:13:55, followed by Ester Navarrete (1:14:18) and Sandra González (1:17:38). Although wind picked up in certain sections, the race remained competitive and engaging until the final kilometres.
In the 5 km event, Antía Castro took the women’s win in 16:14, while Adrián Sancho led the men’s field in 14:52. The medal ceremony in María Pita Square, attended by local authorities, provided a fitting finale to a high-quality day of racing.
Performance analysis: keys to the record
The new course record did not happen by chance. The flat, traffic-free layout allows runners to maintain a consistent rhythm with minimal disruption. Weather conditions were favourable, with temperatures around 11°C and no rain, offering near-ideal racing conditions for a half marathon.
Kipkurgat adopted a smart approach: a controlled start followed by a negative split in the second half of the race. From kilometre 15 onwards, he gradually increased the pace, demonstrating excellent energy management. Carlos Mayo maintained an even effort from the gun, while Jesús Ramos opted for a slightly faster opening phase before managing the final kilometres. In the women’s race, the duel between Brea and Navarrete was decided by a decisive surge in the closing stages.
Tips for training for a flat half marathon
A flat course encourages runners to chase a personal best, but it demands discipline and specific preparation. If you’re considering running a half marathon like Coruña 21, keep these recommendations in mind:
- Develop a strong aerobic base. Gradually increase your weekly mileage and prioritise easy runs to build endurance.
- Train at race pace. Include tempo runs of 4–8 km and structured sessions such as 2 × 4 km or 3 × 3 km at your goal pace.
- Incorporate strength and technique work. Strength training for legs and core improves running economy and reduces injury risk.
- Practise your race nutrition. Test your hydration and fueling strategy during long runs to avoid surprises on race day.
- Plan your pacing strategy. Break the race into 5 km segments to stay focused and keep splits consistent.
On flat courses, it’s easy to get carried away by the early pace. Staying disciplined from the first kilometre and maintaining steady splits is often the key to finishing strong and achieving a personal best.
