Corporate/Company Team
For the (Halve) Hollandse 100 2024, we've developed a corporate program that makes "exercising together for a good cause" very simple. Company teams with 10 to 30 participants prepare themselves for De Hollandse 100 this way. Curious? Request the presentation via info@lymph-co.com.

Event
During the Hollandse 100, there will be performances, DJs, kids' entertainment, and other activities. It's a true family event, so feel free to bring them along. After 45 kilometers, you'll finish at Thialf again, so you'll have 2 moments where people can cheer you on.
