Spaarnwoude Park Ultra

June 14, 2025 @ 09:00 - 17:00
€10

There is no finish. There is only one finisher. The last man standing.

A 3.6 km round through a beautiful nature reserve. You have 30 minutes per round. Every round you complete within 30 minutes means: you can start for the next round. How many rounds do you run? 🙂

The starting area is a lovely spot at the play pond, in the grass. There is a toilet, an outdoor shower and enough space to put your chair, food and drinks and support crew. Supporters are also well catered for: in good weather you can get into the water and there are play equipment.

Each new round starts and ends at the play pond. Time left before the next round starts? Eat and drink something, rest a bit and recharge for another round. And whether you run 1, 5 or 20 rounds: there is no finish so everyone is a winner!

Practical: make sure you are there well in advance, preferably at 08:30. This will give you time to settle in before we start. At 09:00 sharp we will walk the first round as a group, in 27 minutes. You will then have 3 minutes, back at the pond, before the second round starts. Oh yes, you must bring everything you eat and drink during the event yourself.

This event is organized by volunteers. There is no medal or competition shirt. This way we keep the costs low and your registration fee goes 100% to our charity (protectukraine.nl). There are two challenge cups, for the best man and woman.

This new run is organized by the running group Loopmeesters from Haarlem. It is not without reason that our slogan is: running together is more fun. Do you have any questions before you register? Call or app Karel Kolb (0617462882), he will be happy to help you.
