"The following year I entered the Big Red Run, a 250km race across five days. Dad didn't talk to me for months because he didn't approve, but I finished second overall.
"I came back from the Big Red Run and quickly decided to run Surf Coast Century 100 again and this time I was allowed to run solo.
"I was the second female to cross the finish line with a time of 9h 36m - that's where I got noticed."
After proving her outstanding ability in ultramarathon running, Bartholomew took to the mountains and it was there that she discovered her real passion for longer hours but shorter distances.
"My biggest achievement so far would be at the Skyrunning World Championships, held in Chamonix, France as part of the Mont Blanc Marathon. It was here that I was titled the Junior World Champion."
Skyrunning is an extreme sport of mountain running above 2000m. In her four years of competitive running, Bartholomew has travelled around the world and said it's one of the most exciting aspects of competing.
"I ran the Tarawera Ultramarathon in Rotorua in 2014 (although it was shortened because of a cyclone) and I'm super keen to get back over to New Zealand and see it again. I decided to extend my running season to include the Tarawera Trail 50km as it's such a beautiful place to visit - I see it as a great opportunity to run some beautiful trails."
The Tarawera Trail Marathon and 50km event are being held on November 14 in Rotorua.
