10 kilometers of skating followed by 90 kilometers of cycling for lymph node cancer research. A unique Dutch sports event with the theme 'Authentic Dutch'. Think of Authentic Dutch entertainment, snacks, decorations, and more.

Together, we will take on the athletic challenge and raise as much money as possible for research into improved treatments for lymph node cancer.

Find 100 kilometers a bit too much? No problem! We have 4 other options for both adults and kids. You can read all about them further below.

Watch the aftemovie 2023!

This 9th edition of the fantastic OER-Hollandse 100 event features a total of 5 parts:

• The Hollandse 100: 10 km skating and 90 km cycling
• The Half Hollandse 100: 5 km skating and 45 km cycling for those who find the whole Hollandse 100 a bit too much
• The Junior 10: 10 km skating on the sacred ice of Thialf for youth up to 18 years old
• The Family/Group Relay: skate as many laps as possible within one hour with your friends, family, colleagues, or teammates
• The Walking Challenge:  walk 10 or 20 kilometers through the beautiful Frisian landscape. The choice is yours!

Participating?

You can do this individually or as part of a team. Wouldn't it be fun to unleash your primal strength with a group of friends or colleagues and achieve a top performance? The more, the merrier!

You can also choose just to skate or cycle. You can even divide it (one skates and the other cycles). However, you always have to register for the entire event.

• The registration fee for De Hollandse 100 and De Halve Hollandse 100 is €100.

For Whom Are You Participating?

You'll have the opportunity to test your abilities alongside many well-known and lesser-known athletes. Skill, perseverance, and a healthy dose of ambition are required to successfully complete this challenge.
