← Amsterdam Marathon
An 8k (5 miles) race is a bit of an odd distance, but the route is nice. You first go through the Vondelpark, underneath the Rijksmuseum and along the canal to eventually finish inside the olympic stadium. It's a great feeling to enter the stadium and run along part of the track!
There isn't that much local support and you don't get to run through the heart of Amsterdam (that would probably be too small for so many runners), but the atmosphere amongst the 7000 runners running the 8k is great.
