This was the first time I'd done a race of this kind, where you don't have a certain distance but have (up to) a certain time.
It was freezing cold, and took a little longer than expected to collect the race bibs, but we were only a few minutes late in starting. The course is a little boring (each lap is only 1km) but I was only planning on doing 10km as part of a training run. Once we got going, I really enjoyed myself - though I'm not sure how many laps I would have wanted to do if I hadn't planned to stop at 10k!
The event was well organised, and there was plenty of parking, clear instructions and happy volunteers. The medal was a nice, fun, different medal, and there was a huge range of homemade cakes to choose from at the end - win!
