Hermans said she is excited for the Hamilton return.
"We were last at the uni grounds in 2015, and it provides the perfect landscape to hold an XRACE. With all this hot weather forecast, I can tell you we will be putting the swimming pool to good use.
"The competitive nature varies not just between teams but families too — we have a lot of two-team families where Mum races with one child and Dad with the other. Some definitely race as hard as they can for bragging rights.
"But competition isn't always the focus. Teams can go as fast or slow as they want — it's completing the course that's the fun and the goal."
