Marino College topped the podium to win both the boys and girls junior pairs titles at last week's junior and intermediate finals held at St Anne's Park.
The students from the Fairview college successfully negotiated the 1.9km course under almost perfect conditions in idyllic surroundings at the northside venue.
In a course that combined general fitness with the skills of map reading, route finding and team work students from several colleges, including the overall winners Marino, Ringsend College, Coláiste Eoin, Margaret Alyward, Coláiste Dhúlaigh and Larkin Community College, put their agility to the test throughout the competition.
On the parkland terrain, which included tackling cross country, running paths, large flatland lakes, hills and road junctions, it was the Marino pairing of Daniel O'Connor and Paul Ivanov who finished in a time of 19 minutes followed by Daniel Byrne and Dylan Bolger of Ringsend in 23:20, with Marino's Fawaz Alsafadi and Italo de Coelho securing third place in 26 minutes.
In the girls' race, Marino's overall skills came to the fore once again with Cheryll Davie and Egshiglan Saule winning in 30 minutes. The Fairview college then claimed second place through Edrial Marina and Isabella Ayadi followed by Eoin's Jessica Smart and Aisling Kelly.
The Intermediate mixed singles and pairs 2.7km course threw up some interesting battles of the wits with the students of Youthreach Bonnybrook and North Great Georges Street sharing the spoils.
Bonnybrook were unstoppable with a clean sweep in the singles competition. Lee Twomey took top honours in 32 minutes followed by Patrick Christopher 44:00 and Jane Dowd 55:00.
The North Great Georges Street pairings of David Kerrigan and Sean Dwyer (38.40) and Shauna Phelan and Aimee Murphy (40:15) finished ahead of Bonnybrook's Kyle McMahon and Gavin Smith.
