On 18 May 2008, Leiden hosts its 18th annual marathon event. Of course, if a marathon sounds overwhelming, there's always the possibility to run a half-marathon, a 10K or a 5K.

Even if you're not a runner, it's still a great time to visit the city! The event turns the city streets into quite a party, with live music and thousands of excited spectators cheering on their friends and loved ones.

If you do participate you can pick up keep-sakes like a t-shirt, a cap, an the always handy umbrella - for a price, of course. Good luck with the training!
