The Ironman Wales marathon course takes place in and around the picturesque town of Tenby. Exiting transition along South Cliff Street, turning left onto South Parade skirting the town wall, travelling north towards New Hedges. It returns on the same route but continuous into the heart of this historic town, taking in The Croft and the harbour.

The course is a four loop run, each loop consisting of just over 10 kilometres of running, before swinging left onto Tenby’s Esplanade to reach the finish line making up the marathon distance.

The course has changed from 2011.  It will not take in Castle Hill which had a very sharp incline and some steps to negotiate, instead travelling out and back on The Croft for views across North Beach and the harbour.  It will also use Crackwell Street, to reach the harbour, returning through Tudor Square which was used in both directions in 2011.
