INTRO

There's a reason that the winning times in Wales are usually a full hour slower than any other Ironman - this is indisputably the hardest 140.6 course in the world. This race combines elevation gain, steep gradients, and adverse weather with an extremely hilly run.  However the epic Welsh scenery and thousands upon thousands of fans lining the entire course make this a once in a lifetime experience.

IRONMAN Wales is a full distance triathlon located in Tenby, United Kingdom. The swim is 2.4 mi, bike is 112 mi, and the run is 26.2 mi. Use the profile tool, route maps, weather forecast, and other tools on this page to more efficiently and effectively train for your race.

RACE REVIEW

   IRONMAN Wales 

Notoriously the hardest Ironman, this course has the longest average finishing time across all age groups in the world, over 13 hours for mortals and over 9 hours for pros. The last few years have also seen a 12% DNF rate - more than one out of every 10 people who try this race fail.

Significant Ascents:

Dozens of “rollers” that could really be categorized as category 2 or 3 climbs. Quite a few of these break 5%, and there is nearly 3km of the course at over a 10% grade:

Obstacles and Other Notes:

  • Along with lots of steep uphills, there are lots of very steep downhill sections too, breaking -10%. None of them are long enough to be technical, but they often have a  turn at the bottom - be sure to review our profile tool to get familiar with these.
  • A long run from the swim exit to transition
  • Due to the amount of climbing and descending, it’s not uncommon to see people choose to ride road bikes with drop bars + clip on aero bars for this triathlon.
