70.3 & Ironman Recovery: What to Do in the First Week

70.3 & Ironman Recovery: What to Do in the First Week

Crossing the finish line is not quite the end of an Ironman; recovery is the final part of the event. Your body has used a huge amount of carbohydrate, lost fluid and sodium, and accumulated muscular damage and inflammation. The longer the race, the more respect that recovery deserves.

What Should You Eat After a 70.3 or Ironman?

My priority is simple: eat!

Personally, my post-race choice is pizza, because finishing deserves a prize. Conveniently, pizza also supplies carbohydrate, sodium and some protein.

Pasta, rice, bread and other carbohydrate-rich foods will help replenish glycogen, while a useful serving of protein supports muscle repair. Research confirms th

at carbohydrate is particularly important during the first few hours after prolonged exercise.

How Should You Rehydrate After an Ironman?

Rehydration matters too, but “drink as much as possible” is not the answer.

Those white salt marks on race suits show that substantial sodium losses can occur, although sweat rates and sodium concentrations vary enormously.

Drink steadily according to thirst, include an electrolyte drink or salty foods, and keep monitoring your urine and general hydration. Forcing excessive amounts of plain water can dangerously dilute blood sodium.

What About the Celebratory Beer?

Alcohol is best avoided that evening. I understand why people want a celebratory beer, but alcohol can interfere with muscle protein synthesis and sleep. If you choose to drink, eat and rehydrate first, and keep it modest.

Beer should be part of the celebration, not your recovery plan.

The First Night: Sleep, Soreness and Ibuprofen

The first night can be surprisingly uncomfortable, particularly after a full Ironman. Sleep may be disrupted by soreness, adrenaline and a generally unsettled body.

I used to reach automatically for ibuprofen, but this is not something I would now recommend routinely. Your kidneys may already be stressed by prolonged exercise and dehydration, and research has linked ibuprofen use during endurance events with an increased risk of acute kidney injury.

Sleeping tablets should not be mixed with alcohol or taken without medical advice.

The Morning After: Start Moving Gently

The following morning, sleep in and then begin moving gently.

My personal discovery was stairs: the first attempt made me feel like Po from Kung Fu Panda, but each trip felt easier.

That does not mean repeatedly climbing stairs should become a workout. A flat walk, light mobility or a very relaxed swim is usually kinder.

Research suggests that active recovery can temporarily reduce muscle soreness, although it is not “flushing out lactic acid”. That disappeared long before the following morning.

Days Two to Five: Don’t Chase Fitness

During days two to five, keep moving without chasing fitness.

Try an easy swim or gentle spin for 20–45 minutes, then judge how you feel the following morning. If the session leaves you noticeably more tired or sore, you probably did too much.

Low-grade inflammation can remain elevated for at least five days after an Ironman. Some athletes may feel ready to begin easing back into structured training after a week, while others need considerably longer. Race distance, experience, conditions and how hard you raced will all affect your recovery.

When Can You Start Training Again?

Only reintroduce intensity when your sleep, appetite, resting heart rate, walking pattern and muscle soreness are close to normal.

A 70.3 athlete may recover sooner than an Ironman athlete, but neither needs to panic about losing fitness during an easy week.

Massage may help with soreness, but the foundations remain food, fluid, sleep and patient movement.

Recovery is not time away from training; it is the final training session of your race.
