Callum Hawkins will join fellow Scot Stephanie Davis at next month's World Athletics Half Marathon Championships in Gdynia, Poland.
The 28-year-old - added to the 10-strong GB & NI team helmed by his dad and coach, Robert - makes his first appearance at the event since 2016.
Hawkins holds the fastest half-marathon time for a European this year, clocking 60 minutes 1 second in February.
Davis, who ran a personal best of 71:15 the same month, makes her GB debut.
Canada-based Scot Sarah Inglis was in the team for the event originally due to take place in March, but has declined selection for the rescheduled 17 October date.
