Martindale competed again in a sprint freestyle double at the 2000 Summer Olympics in Sydney, Australia. She achieved FINA B-standards of 26.91 (50 m freestyle) and 58.36 (100 m freestyle) from the Pan American Games in Winnipeg, Manitoba. In the 100 m freestyle, Martindale placed twenty-fourth on the morning prelims. Swimming in heat two, she came up with a spectacular swim on the final length to a top seed in 57.21, sufficiently enough for her personal best. Two days later, in the 50 m freestyle, Martindale posted a time of 26.05 from heat six to share a twenty-third seed with Australia's home favorite Sarah Ryan in the prelims, but missed the semifinals by almost a tenth of a second (0.10).
