"I fractured my left hand and got several stitches to my knee but I also had a really bad concussion so that's what kept me away from work for six months."
The former Havelock North High School pupil found the rear end of Te Mata Peak very slippery today although she landed on her backside a few times even on the flat but relieved no one saw her.
"I basically had to crawl up because you could not walk up or you'd have been sliding down," she said, juxtaposing that with hot and dry conditions in 2015.
Christine Lear, of Gisborne, was second in a time of 4:46:03 while Brona Turley, 19, of Havelock North, who heads off to Australia soon for her OE, was third in 4:51:11.
Bywater came away today with some "mental toughness" but also cherished support from a group of three-male team relay runners - Clint Wright, Jeff Curran and Spencer Bartlett, of Nfinite Fitness Trio - who kept encouraging her to soldier on despite the trying conditions.
"It was also good encouragement from other competitors, volunteers and marshals to carry on," she said, alluding to 2015 when it got a little lonely when an athlete often didn't come across someone for lengthy spells between the three peaks.
"Today's race was much more sociable and much better."
Bywater said while her time was 5h 2m in 2015 she thought today's distance might have been shorter even though organisers said the 3 x 16km loop made it a kilometre longer than the three-peak circuit.
"I'm not sure if they calculated it correctly because I had my GPS watch on so please check with the officials," she said although factoring in the possibility of crossing rivers might eat up more time than going around one peak three times.
Bywater picked up running while attending Otago University, taming the trails before entering a few half-marathons and the Hawke's Bay Trail Series.
"It was my stress relief. I just enjoy it because it's time out and good for my mental health," she said, entering the 2015 Triple Peaks just to say she had done it.
She isn't the type to pre-plan her next event but gauging how she feels before committing.
What will she do to celebrate tonight?
"I'm going to be babysitting my nieces. I'm going to the prizegiving this afternoon and then just relax, have a bath and watch a few movies, maybe."
