I’ve entered a lot of races and this was by far the most fun, friendliest and had the best, well stocked fuel station. The route had a bit of everything and was marshalled by lovely encouraging people. The organisation and the team were just happy, chatty and beyond helpful. The fuel station is the best fuel station I have ever seen! I can’t do anything but recommend them :0)
Great event, fabulous for pushing your distance by doing an extra lap, did my first hm here
It was our first time doing a Rasselbock event. We loved it. The organisation and atmosphere was great.
