Seven events take place in regional parks around greater Auckland each winter and Daulton cites the variety of locations as a big drawcard.
"I don't have a favourite but I do like Riverhead Forest - so much mud," she laughs.
Event manager Kezia Trask is quick to point out mud is not the only type of course on offer.
"Muddy Riverhead may not be everyone's favourite. Some prefer well-groomed and easily accessible Totara Park. Others like the rugged isolation of the Hunua and Waharau courses. This weekend's participants will be looking forward to the seascape at Shakespear - one of Auckland's hidden gems."
Daulton is pragmatic about the physical restrictions on her training as she considers the outstanding mental benefits afforded to her.
"At the moment, I am having to walk a lot but constantly set little goals for myself during the event like running a tricky downhill section or passing the person in front of me. I'm doing some strength training that is really helping my core and I know I will get fitter as the season goes on.
"For me, it's not about being fast, it's about spending time outdoors with fabulously supportive people."
Trask is proud of XTERRA's inclusive reputation.
"People sign up for different reasons - to keep fit, lose weight, for their mental health, to get five minutes with the kids or five minutes away from them! I love standing at race briefing and seeing people of all abilities and from all walks of life together in these beautiful places."
