"I want to do my best and I've always gone by personal best. I haven't reached my goal yet," she said.
This season she has joined the Wanganui Cycling Club, which has lots of cyclists over 30. She said it was a great club and had been very helpful.
She's in a group voluntarily coached by Ron Cheatley. They do training rides every Tuesday and Thursday at the velodrome.
"He is a great trainer. He gets you working, and that's what I want."
On other days there are individual programmes. A 60km easy ride, for example, might be out toward Westmere, Papaiti or Upokongaro. Afterward the cyclists might have coffee together.
She rides an average 200km across five days of a week, in all weathers.
"You have your time for training that you can do and you have just got to use it. You get warm while riding."
Mrs Nesbitt is self-employed, with children aged 13 and 15 and husband Paul, who is a runner. On training days she will finish work, go home and take her bike to the velodrome.
She's competed nationally, and is on the waiting list to ride in the World Masters Games Cycling in Auckland this year.
After her last event in the Whanganui Masters on February 6, Mrs Nesbitt will be settling back into her usual training regime.
"I have learned a lot this season, and got a lot to learn," she said.
