Jonny Steede will start favourite for Saturday’s Spelga Skyline Race in the Mournes.
The 12.5 miles event – which includes 1550 feet of climb – is the sixth round of the Northern Ireland Mountain Racing Championship.
Steede, from Ballymena Runners, won at Commedagh, Annalong and Flagstaff and should increase his lead in the overall standings.
Seamus Lynch has been second to Steede in the last round and can take runner-up position again with Deon McNeilly, David Steele, Ian Bailey, Neil Carty and Alex Brennan also prominent.
Diane Wilson has been dominating the women’s scene both in this series and the Hill and Dale.
She should win again comfortably with chief rival Shileen O’Kane not expected to compete due to injury.
Catherine O’Connor will be next best if she goes with Hazel McLaughlin, Anne Sandford and Denise Mathers also disputing places.
The race starts at 11am from Spelga car park with registration from 9.30am.
Meanwhile, Glenn Phair from Annadale will be the favourite for Saturday’s third Lisbellaw 10k Road Race in Co Fermanagh.
The defending champion, who is from the county, has already come first at both Enniskillen and Lisnaskea and should complete his treble.
Conan McCaughey from Enniskillen has been going well and can take a medal along with Dromore runner-up Paul Barbour and Fergus McGirr.
Denise Toner from Clones is the holder of the ladies title and will be going for a double.
Helen Stockdale and Donna Evans will go close while there is a chance that Dromore and Enniskillen winner Patricia O’Hagan will make an entry.
The race starts at 11am.
Elsewhere, Aislinn Crossey, Megan Marrs, Roseanne McGuckian and John Kelly are expected to be the leading Ulster competitors in Sunday’s Glohealth Irish Junior and U23 Championships at Cork IT.
