Brian Fay, Fiona Everard, Niamh Allen and Noah Harris will represent Ireland at the World Cross Country Championships that take place in Tallahassee, Florida in January.
Scheduling has meant that some of the European Cross Country Championship athletes that performed so well in Lagoa, Portugal last weekend were unavailable for selection.
Fay, like Everard, finished 10th in his senior race and will be hoping to carry that form into the Worlds.
The 5000m Olympian has enjoyed a memorable cross country season to date, winning the national senior title in November before being a scoring member on the Irish team in Portugal.
It will be his debut appearance at the World Cross Country Championships.
Everard returns to this stage having finished 60th in the senior women's last year in Belgrade.
The Cork woman had the run of her life last weekend, coming through the field strongly to crack the top 10 at the European Cross Country Championships, which backed up her national cross country title last month.
Leevale’s Allen finished 23rd in Lagoa last weekend and similar to Harris, will be making her World debut.
Harris, the 18-year-old from Wicklow, is currently studying at the University of Tennessee and will be looking to gain valuable experience in Tallahassee.
"We are pleased to be sending a small but high-quality team to the World Cross Country Championships in January," Mark Kenneally, Athletics Ireland Performance Endurance Lead said.
"The new place in the calendar has meant that a number of our European Cross Country Championship athletes are unavailable, with a focus on other priorities, but we believe that the selected athletes are capable of competing with the best athletes in the world, coming in with exceptional individual performances from Lagoa."
