How the ranking works. Courses are ordered by bike elevation gain, the climbing figure that the most races publish. Equal climbs are split by run elevation, then by race-day heat. Water, air temperature and cut-off sit beside each race, so you can see what the climbing figure leaves out.
10 races in this group publish no elevation figure and are not ranked.

What makes an IRONMAN course easy
Over 180 km, climbing is what separates one bike course from another most clearly, and it is a number you can compare. That is why it orders the list.
Easy is relative, though. A flat course in the heat can be harder than a rolling one in cool air, and a non-wetsuit swim in warm water asks more of a weak swimmer than a cold lake in neoprene. Read each line to the end. For the other end of the scale, see the hardest IRONMAN courses; for a first attempt, the best IRONMAN for beginners also screens out heat and cold water.
This page ranks full-distance courses by climbing alone. For a first full distance, the best IRONMAN for beginners page adds water and heat filters; for the half distance, see the easiest 70.3 races.

The flat label and the measured climb
12 full-distance IRONMAN races carry a flat label on both the bike and the run: IRONMAN Florida, IRONMAN Cozumel, IRONMAN Western Australia, IRONMAN Vietnam, IRONMAN Brazil, IRONMAN Kalmar-Sweden, IRONMAN Belgium Knokke-Heist, IRONMAN Japan South Hokkaido, IRONMAN Italy Emilia Romagna, IRONMAN Maryland, IRONMAN Calella-Barcelona, IRONMAN California.
The label describes the character of the terrain, not a limit. IRONMAN Barcelona is labelled flat and still climbs about 750 m on the bike. When a figure exists, trust the figure.

What the climbing figure leaves out
Heat. 10 full-distance IRONMAN races see average highs of 30 °C or more on race day, and several of the flattest courses are among them.
Wind and road. A flat coastal course is often a windy one, and no elevation figure measures it.
The swim. Above 24.5 °C the wetsuit is no longer allowed for age-group awards. Warm, flat races often come with a swim in a thin suit or skin.

What is the best IRONMAN for beginners?

Is the easiest course the fastest?
Usually the flattest courses give the fastest bike splits, but wind, heat and the swim decide as much as the terrain. Fast times are a matter of conditions on the day.
