Rheinpark Parkrun, Cologne

There's plenty of public transport in Cologne (see the course page for more), and it's very accessible given the 9 euro ticket, but I chose to walk to Rheinpark. I was based very near the other parkrun, Aachaner Weiher in the Hiroshima-Nagasaki park, but it was still only a couple of miles to walk to Rheinpark.
There are toilets 400m from the start, with a free urinal for men and a cubicle that's €0.50.
The start and finish are in the same place, just beyond (if you're approaching from the South) a covered part of the walkway in front of the Rheinterrassen Köln.
The start takes you right next to the river for a short while, before a right turn to head into a tree-lined loop. You're very briefly taken out of the park, past a low concrete wall, before following the twisty route back towards the river. The top section of the course has two long straights, the first along a mud-packed or grassy path (depending where you put your feet or who is in the way), then back along a wide gravelly road. The latter seemed particularly long, perhaps because it was almost entirely in the sun on a day warming towards 34 degrees (but 'only' low 20s for the event).
The course is very well marked, with arrows to point you in the right direction and red cones on either side of the correct path. Despite that, one runner ahead of me tried to head through a narrow gap as we headed back towards the river - we waved her back onto the path, but her mistake was understandable, as we were looking for the path by the river, and going through the trees would have taken her closer. That North section, then, is by the river, but not right by it, which is worth bearing in mind.
Making the turn after the long earth path takes you onto a few cobbles and then that long gravelly section. Nothing much to do here but get on with it, as the route takes you past port workings and grass.
I struggled on the second half of the course, and was glad to see the bridge and some shade, before attempting a bit more of a gallop towards the finish. The Cathedral comes into view but by then I was more excited by the finish - from any distance, it's easier to spot the complex that stands above it, and that covered walkway, than the parkrun flag, but you can't miss the finish when anywhere near.
The whole event was well run and organised. There was no move to a cafe at the end, with people wandering off to do their own thing, and I made it back to the centre of town before it got really hot. There are a few cafes to the South of the route, which were opening up as I walked past, though they looked more focused on drinking, and I think I would have tried the West side of the river for preference if I'd fancied going anywhere. Instead, I enjoyed the sun and the warmth of the city before a well-earned shower back in Neumarkt.
