The countdown has begun. Registration for the 36th Leiden Marathon opens on Thursday, 1 October at 12:00 noon!

On 8 and 9 May 2027, you can take on your own personal challenge in Leiden. Will you go for the 5K, 10K, half marathon or full marathon? Or join the free Kids Run? The 5K will once again be a spectacular Nightrun.

There’s plenty of choice for walkers too. On Saturday, you can take part in the 10K, 21K or 42K walking events.

It may still seem a long way off, but last year’s entries filled up quickly. Want to be there in 2027? Mark Thursday, 1 October at 12:00 noon in your calendar.

Just a little more patience. We’re almost ready to go!
