Form a team of four, lace up your running shoes, and support the LUF Children’s Fund. Whether you're a seasoned runner or just looking for a fun day out with colleagues, friends, or fellow students – everyone is welcome!
The Leiden Science Run is the perfect combination of sport, solidarity and supporting a good cause. Don’t miss out – sign up now and we’ll see you at the starting line!
Adjusted start schedule due to warm weather forecast
Due to the warm weather forecast for Saturday, June 21, the start time of the Leiden Science Run has been moved forward to 10:00 AM (instead of 12:00 PM). This way, you can begin your run during the cooler morning hours and enjoy it to the fullest!
Note: Instead of the original relay format, team members will now start individually at 10-minute intervals.
Make sure you’re well prepared: we recommend moisture-wicking and breathable sportswear. Don’t forget essential sun protection, such as a cap, sunglasses, and sunscreen. Also, be sure to arrive well-hydrated and continue drinking enough fluids throughout the run. There will be plenty of water and sports drink stations along the route for everyone.
