Katrina Jane Weston (née Colebrook, formerly Finch; born 8 November 1957)[1] is a former British middle distance runner who specialised in the 800 metres.

Born Jane Colebrook in Lincolnshire, she started out as a sprinter and won the under-15s 200 metres race at the 1972 AAAs Junior Championships, with her sister Teena, at Yarborough School in Caistor,[2] living in Nettleton.

[12] That July, she ran her lifetime best for the 800 m outdoors in Oulu, Finland, clocking a time of 2:00.6 minutes,[13] which made her the second best British performer in the event at that point, behind Rosemary Stirling.

[16] Colebrook went on to represent England in the latter event at the 1978 Commonwealth Games and won the bronze medal behind Judy Peckham and Tekla Chemabwai.

[24] Her sister, Teena Colebrook, was also a runner and won seven NCAA Division II titles in middle distance events for California Polytechnic State University.
