With the SSE Dublin Marathon just over three weeks away, Sergiu Ciobanu of Clonliffe laid down a marker when he won the Cork to Cobh 15-mile race by more than three minutes.
His time of 78 minutes 47 seconds was good - though not as good as his own course record of 76 mins 42 secs, set four years ago. Still, can anyone stop him taking a third national title on Marathon Monday?
Simon 5-mile calling
Fun runners young and old are invited to line out in Sunday's Simon 5-mile fun run (10.0) - one of the first ever charity runs held in Dublin and certainly the first to use the Phoenix Park.
Children under the age of 12 go free, while schools can also register unlimited numbers of their pupils for just €20.
For everyone else, entry is €20 (€25 on day).
A children's zone will operate from 10.30am.
Athlone 3/4 looms
Looking for a final fitness test for the SSE Airtricity Dublin Marathon? Sunday's Athlone Three-Quarter Marathon is designed to give runners a chance to test their pace before the big day.
The course, from Glasson, does have a rolling hill or two, but is virtually traffic-free.
Distance is exactly 31.646km or 19.664 miles.
Airlines do battle!
Aer Lingus and Ryanair will do battle this weekend - but with feet firmly on the ground.
Teams from both airlines have entered the 33rd annual World Airline Road Race in St Anne's Park and - at the very least - honour is at stake.
In total, 122 teams representing airlines and associated companies from all over the world will be in action.
Dublin has hosted the race before - it took place around the city centre in 1993, when new-fangled electronic timing was used for the first time at a race in this country.
