The NN Marathon Rotterdam has assembled one of the most formidable men's fields in the race's history for its 2026 edition, with eight runners carrying personal bests under 2:07 set to contest the April 12 race. The Dutch classic, which starts at the foot of the iconic Erasmus Bridge and finishes on the Coolsingel in front of Rotterdam's city hall, has long been regarded as one of the world's premier road racing venues — three world records have been set on its flat, sea-level course — and the quality of this year's field suggests another fast day of racing is anticipated.
Leading the men's entry is Laban Korir, a figure well known to spring marathon fans after years of consistent high-level performances across Europe. Korir, whose 2:05:54 lifetime best came from a commanding win at the Amsterdam Marathon, will be targeting the podium on a course that suits his ability to run to pace and kick hard in the closing stages. He will face a deep and competitive field that includes multiple East African athletes who have tested the 2:06-barrier in recent campaigns, making the men's race genuinely difficult to call from the outset.
The women's race is expected to feature a similarly competitive lineup, with athletes targeting personal best performances on a course that has historically delivered quick times for both fields. Rotterdam's flat, wind-sheltered route through the city centre and along the Maas waterway provides near-ideal conditions for sub-2:20 women's performances when the April weather cooperates. Race organisers have emphasised the depth of the women's entry in the days leading up to the event, though full field confirmations are expected closer to race weekend.
Rotterdam has long distinguished itself from other spring majors by maintaining a focus on speed and competitive integrity. The race attracts over 925,000 spectators lining its urban course, creating an atmosphere that veteran runners describe as among the most electrifying in European road racing. The weekend itself extends beyond the main marathon, with a city run, quarter marathon, kids' events, and a business team relay adding a community dimension to what is also one of the Netherlands' largest annual sporting occasions. Over 35,000 athletes participate across all events, making it the biggest one-day sporting event in the country.
With Boston and London both taking place a fortnight later on April 19 and 27 respectively, Rotterdam occupies a distinctive position in the spring calendar — attracting elite runners who prefer a lower-profile, fast-first race rather than the spotlight of the World Marathon Major circuit. For several of this year's entrants, a strong performance here will serve as a significant statement of fitness heading into the summer track season or autumn marathon circuit. Race day in Rotterdam is Sunday 12 April, with the marathon gun scheduled for 11:00 local time.
