Spaarnwoudepark Ultra

June 13 @ 09:00 - 21:00
€25

After two fantastic editions in 2025, we're back for two more in 2026: in June and December. Registration is now open, with a maximum of 150 participants. How far will you go? : )

A 3.6 km loop through a beautiful nature reserve. You have 30 minutes per lap. Each lap completed within 30 minutes means you can start the next lap. How many laps will you run? : )

New: in addition to the 3.6 km loop, you can also choose the 4.6 km loop in June. This distance must also be completed within 30 minutes. You can decide on the day of the event which distance you want to complete for each loop.

The starting area is a lovely spot by the play pond, on the grass. There are restrooms, picnic tables, and plenty of space to set up your tent, chair, food, drinks, and support crew.

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!

A practical note: make sure you arrive well in advance, as the runners' briefing is at 08:45 AM. This will give you a chance to settle in before we start. At 09:00 AM sharp, we'll run the first lap (3.6 km*) as a group, in 27 minutes. Back at the pond, you'll then have 3 minutes before the second lap begins. The last lap starts at 20:30 PM. Oh, and you're responsible for bringing all your own food and drinks during the event.

*The first 4.6 km lap also starts at 09:00 AM, with a leader. You'll then have a slightly shorter rest period until the next lap (which starts at 09:30 AM).

This event is organized by volunteers. This allows us to keep costs low. Furthermore, €5 per registration goes to a charity (this time it is the MIND foundation ). There are four challenge cups, for the fastest man and woman (in the final lap, for the 3.6 and 4.6 km). Everyone who runs 24 laps receives a nice souvenir.

This running festival is organized by the Loopmeesters running group from Haarlem. Our slogan is "running together is more fun" for a reason. Any questions before registering? Call or text Karel Kolb (0617462882); he's happy to help.
