The Phoenix Park Duathlon race course is based close to the Papal Cross in the Phoenix Park.

The duathlon in April will consist of:

    • Run 1 – 5km (2 laps)
    • Bike – 21km (3 laps)
    • Run 2 – 2.5km (1 lap)

Run 1 is an anti-clockwise loop of the playing pitches area of the 15 Acres following the tarmac track; the route is flat. All traffic cones must be kept to your right. There will be lots of marshals present and anyone found cutting corners will be disqualified.

You must enter and exit transition by the official entry and exit points. We have a neutralised transition and places are not allocated. All boxes and bags will be removed from transition before the race. The usual TI rules on nudity will be observed and applied. You must put your helmet on before touching your bike.


April race  (1 lap = 7km anti-clockwise)

This race is non-draft legal. View an interactive map here.

The new bike course consists of 3x laps of a 7km circuit on closed roads, with all left hand turns. It’s a technical course – with 200m of climbing in total over 21km and lots of turns. The direction is anti-clockwise – after crossing the mount line, cyclists will proceed right up Acres Road, proceeding left at the Phoenix Monument Roundabout onto Chesterfield Ave. After 500m turn left onto Furze Road and proceed to the end, taking the junction left onto Glen Rd.

A fast descent after the S-bends, into a narrow left turn (caution: poor road surface at corner, so slow down). Heading across the lane you join the Military Road and continue around the S-bends before descending to the Khyber Pass corner. Then the 1km climb starts until you complete 1 lap. Stay right to continue onto lap 2 – after your 3rd lap stay left to enter Acres Road and proceed to the dismount line.
