Harvey had a three-week break from racing earlier this year. She had been lacking energy but has got her legs back.
The 22-year-old battled through heavy rain to finish fifth at Gran Premio Ciudad de Ebiar in Spain at the weekend.
Team-mate Hannah Barnes had put herself in the main breakaway but was caught approaching the final climb. Harvey’s team pulled together to put her into a good position and the climber went to work.
Anna van der Breggen claimed the win but Harvey was thrilled with her effort.
“The team plan was to protect me for the final climb and for my team-mates to patrol the front for breakaways," she said on her team’s website.
"Everyone rode so well for me all race so I was very motivated on the final climb. My job was only 6km long and I was ready to battle.
“Halfway up the climb our group caught the leading three. I went to the front to keep at my own pace.
"When the next attack went, I couldn’t follow but I just kept chugging along at my own tempo.
"With a bit more work, I hope I can follow the moves for a podium result on finishes like this. However, I am really happy with the result."
Last week, Harvey grabbed a courageous sixth at the Emakumen Nafarroako Klasikoa.
It was another tough slog in the rain but Harvey seems to enjoy the wet conditions.
She has always been a good climber but has made gains going downhill. She joined a breakaway on a descent.
Fellow Otago rider and Harvey’s team-mate, Ella Harris, finished 52nd in the Gran Premio Ciudad de Ebiar and 30th on the Emakumen Nafarroako Klasikoa.
