I have a bit of mixed feelings about this marathon. Some things were well organised, but other things really were not and that's really a shame for such a big event (it's the 3rd largest marathon in the world).

It's really easy to pick up your bib, but do make sure you have your passport, convocation and medical certificate before you arrive at the expo. There were a lot of companies at the expo, but most of the company booths at the expo were pretty small, so per brand there wasn't that much choice. 

There were no signs towards the bag drop (which is at the finish area), which resulted in a lot of runners looking around in confusion. There were a lot of port-a-loos near the start, so didn't have to wait long in line.

The route is really nice and passes several landmarks and there are even signs on the course telling you which landmark you are passing. And since the route passes along a few metro lines it's really easy for supporters to see you multiple times along the route. 

But the aid stations were pretty disastrous. They were only on one side of the road, and a pretty random intervals (sometimes 5, but also sometimes 6 km apart), which is already difficult with roughly 40,000 runners. They don’t supply any kind of sports drink, only water and since it was hot they couldn’t supply water fast enough, which resulted in the aid station tables being mostly empty and having to wait quite long before getting water with a lot of people pushing and shoving trying to get water. They should have had more aid stations, since it was so hot. I’ve heard quite a few ambulances during the race, some of those cases they could probably have prevented if they supplied more water and electrolytes.

At some spots the supporters were blocking half the road trying to find who they were looking for, but this caused congestion amongst the runners. Marshals did nothing to stop it. They also didn't stop any of the cyclists which were using the course and actually creating dangerous situations. 

Getting your medal, finisher t-shirt and bag at the finish area is really easy.
