Hopes are high that wheelchair whizzkid Patrick Monahan will become the first Irishman to break two hours at Monday's SSE Airtricity Dublin Marathon.
Monahan won in 2:06.21 at Belfast in May, beating many times Dublin winner Paul Hannan.
Last month he recorded a sensational 53.51 at the Dublin Half Marathon. Richie Powell from Wales will take him on in Dublin.
O'Neill on top in Park
At the Autumn Open Cross-Country in the Phoenix Park, the men's race provided the drama.
Breandan O'Neill of Dundrum South Dublin produced a burst of speed to pass Mullingar's Mark Christie in the closing stages of the race for victory.
Christie was pipped by Kevin Maunsell of Clonmel for second.
Michelle Finn of Leevale ran a fine race to finish second behind Fionnuala Britton.
Traynor the Master
Sunday's Autumn Open Cross-Country also served as a trial for the British and Irish Masters next month in Nottingham.
Closest race came in the M45 age group, where Mick Traynor squeezed out his Raheny clubmate Des Kennedy, and Damien Martin made it a Shamrock hat-trick when he finished third.
Aisling Mac Dhomhnaill of Donore was first W35; Niamh O'Sullivan of Ríocht was fifth master overall and first W50.
Curley in contention
Pauline Curley of Tullamore put the final touches to her Dublin Marathon preparations with a second place overall in the Longwood 5km in Co Meath.
At the Dublin Juvenile Championships in the Phoenix Park, DSD beat Clonliffe for the M18 title. Pierre Murchan of Celtic DCH was the race winner with Clonliffe pair Cathal Doyle and Adam O'Brien 2nd and 3rd. Despite that, DSD took the team title. Winner of the girls' U18 race was Clonliffe's Hope Saunders.
