Two women in athletic gear hold hands and raise them victoriously as they cross a race finish line. Both are smiling and appear happy. They are wearing white shirts with bib numbers 3501 and 3502. Spectators and colorful flags are visible in the background. A large group of runners gathers at a starting line for a race, beneath a banner reading "START." Spectators cheer from the sides, and officials in colorful jackets prepare to begin the event. The background features open countryside and parked cars. A group of young runners dressed in colorful athletic wear are starting a race on a road marked with the word "SLOW." Spectators and participants in yellow shirts stand in the background, and trees line the course on a clear day. Two cyclists ride along a forest trail with greenery and trees surrounding them. One cyclist leads in the foreground wearing a helmet and sunglasses, while the other follows in the distance. The path is dirt, and signs can be seen along the sides of the trail. Three men celebrate at a race finish line. The man in the center triumphantly holds a bicycle over his head while wearing cycling gear. The other two men stand on either side, smiling and wearing athletic apparel. A "FINISH" sign is visible in the background.

I did the 10k race and found it well organised so everything went smoothly from the parking to the run, getting a medal and goodie bag at the end and everything in between. Beautiful setting and a great route. There’s a big hill at the start and the rest is undulating. We had perfect running conditions for it which helped.

The route was good and despite the rain I enjoyed the run. At the start we were circled too early into the pens (30mins before is too much). Worse though there were a number of very annoying problems and poor organization at the finish. 1. It was cold at the start line so I kept a fleece on until starting and left it at the start line intending to pick it up at the end. When I finished I found it had “been cleared”. Others had done the same and everything was gone. No one could tell me where to or how I could get it back. I ended up wandering around for 20 minutes, soaked through and freezing cold, looking for lost property which none of the staff or volunteers could direct me to (“white tents” but which white tents?) I lost my fleece which was super annoying! 2. At the end the last 200m was barriered and a nightmare to cross. Security Staff blocking the crossing points were people lacking any common sense. They were told a certain gap was required to let runners cross but that meant I waited (twice) for at least 5 minutes. I and many other runners were left cold and shivering in the rain (staff had warm coats on). When asking politely to cross with reasonable gaps we got patronizing, unhelpful and dismissive responses. Doubly annoying is that the route did not need to cross itself - there was space “above” the route for the big tents etc. at the end making this a problem which didn’t need to happen. Volunteers were kind but overall my interaction with paid staff was not good and ruined the day for me. Good I’m irritated just writing this out!
