At the 1978 Commonwealth Games in Edmonton, she won a bronze medal in an English sweep of the 100m hurdles final, with a wind-assisted 13.17, finishing behind Lorna Boothe (12.98) and Shirley Strong (13.08).

She did win a gold medal in the relay, along with teammates Bev Goddard, Kathy Smallwood and Sonia Lannaman.

After several quiet seasons and now competing as Sharon Danville, she ran 13.66 to finish third in the 100m hurdles at the 1983 UK Championships behind Shirley Strong and Pat Rollo.

She earned selection for the Los Angeles Olympics in 1984, where she ran 13.46 in her 100m hurdles heat to qualify for the semifinals, where she improved to 13.35 for fifth in the second semi, missing the final by one place.

The Sharon Colyear-Danville Season Opener track meet, held at Boston University annually in December, is named after her.
