Career
She was made an Administration Member of the Order of the British Empire for services to cycling in the 2002 New Year Honours. McGregor competed in running until the age of 28, scoring an eighth-place finish at the 1988 World Fell Running Championship, and did not ride a bicycle until she was 17. She started cycling competitively when she took up competing in triathlon, finishing third in the British Triathlon Championships in 1990, and focused on it when she sustained an injury to her Achilles tendon.
In 1993 she broke Beryl Burton"s 20-year-old British 10 mile time trial record with a time of 21 minutes 15 seconds.
On 17 June 1995 in Manchester she set an hour record for women of 47.411 km. McGregor broke Burton"s 25 mile time trial record in 1996, setting a time of 51 minutes 30 seconds.
Following rule changes to the hour record (which disallowed the bike and position she used to set the record in 1995), McGregor set a new European and sea-level hour record of 43.689 km on 13 April 2002. This remained the British record until Sarah Storey surpassed it in 2015.
This marked the end of McGregor"s competitive cycling career.
Since retiring from competition she has worked as a sports massage therapist.
