8. Adjust your training plan. Half-iron and iron distances require a full week (70.3) to 10–14 days (Ironman) to recover. But these are minimalist guidelines for athletes eager to get back to training for their next race—there’s nothing wrong with taking an extra easy week or even a whole month after an Ironman if you feel you need it. Always err on the side of caution with recovery—missing a week early on may save you many weeks of fatigue and frustration later.
