McCulloch, who lost her Team Sprint teammate Stephanie Morton to retirement after Rio 2016 and seriously injured her back in the lead up to these Games, finished ninth overall after two big days of racing.

From qualifying through a repechage on Wednesday, the 33-year-old finished second in her quarter-final behind Canadian Kelsey Mitchell and then fifth in the semi-final which was won by Dutch rider Shanne Braspennincx.

In her final race of the night to determine placings seven to 12, McCulloch was third behind German Emma Hinze and Hong Kong's Wai Sze Lee to finish ninth overall.

"I got a bit caught in that last bend and ran out of legs, but I executed my strategy great in the quarters, semi and the final so I couldn't ask for anything more," McCulloch said.

"I was thinking to myself 'come on legs, keep going' and unfortunately they didn't do it for me. I ran a bit of a risk with my strategy, I had probably the biggest gear on and it hurt me in that last quarter.

"Obviously I would have loved to have been in the [medal] final but it wasn't meant to be, and ninth in the world considering where I've come from over this last 18 months with Steph retiring and my back blowing out, I'm just happy to be here."

McCulloch will close her Tokyo campaign with the Individual Sprint which starts on Friday.

"I haven't done as much preparation for the sprint, I'm hoping for a PB in the flying 200m, that would be icing on the cake for me and I'll take it a race at a time and be a bit of a menace out there."

Meanwhile Sam Welsford finished 11th overall in the Men's Omnium after backing up his bronze medal performance in the Team Pursuit.

Welsford was ninth on the placings after the scratch and tempo race, then 11th after the elimination and points races.

"It's been a rollercoaster of a four days. I think it did take a bit out of me the team pursuit, especially with everything that went on, but it was a super hard day out there today," Welsford said.

"I had good legs and speed in the morning but the backing up with short recovery was really tough for me today.

"I'm proud that I went out there and emptied the tank and threw the kitchen sink at it.

"I look back on the week we've had and I still come away with a bronze medal (in the Team Pursuit) which is awesome and it feels pretty special."

Day five of racing in the velodrome on Friday features Annette Edmondson and Georgia Baker in the Women's Madison while Kelland O'Brien and Leigh Howard will race in the Men's Madison on Saturday.
