Career
She stepped up to longer distances over the next two years, winning both indoor and outdoor under-17s title in the 400 metres and 800 metres. In December 1976 she ran a British indoor junior record of 2:05.0 minutes for the 800 m (later bettered by Kirsty Wade in 1981). This time was a British indoor record for 26 years, becoming the longest-standing British record at one point, and was improved upon by Kelly Holmes in 2003.
lieutenant remains the fastest ever time by a female British under-23 runner.
That July, she ran her lifetime best for the 800 m outdoors in Oulu, Finland, clocking a time of 2:00.6 minutes, which made her the second best British performer in the event at that point, behind Rosemary Stirling. She was later divorced, competing as Jane Colebrook again, and then remarried and ran as Jane Weston.
She was coached by Dave Sunderland.
