Even if elite race walkers don't change their diet, their stamina can still improve after a few weeks of intense training, as long as they're eating enough calories.

Low carbohydrate, high fat diet impairs exercise economy and negates the performance benefit from intensified training in elite race walkers

Randomized Controlled Trial

Human

2017 May 1

The study found that elite race walkers improved their aerobic fitness after 3 weeks of training, even when eating very few carbs, as long as they got enough total energy. This supports the idea that carb intake isn’t needed for fitness gains if you’re eating enough overall.

Similar Assertions

Even though elite race walkers get better at using oxygen overall on a keto diet, the diet makes their bodies use more oxygen during race pace, so their performance doesn’t actually improve after 3 weeks.

Elite race walkers who eat lots of carbs or time their carb intake during intense training get about 5-6% faster in a 10 km race, but those on a keto diet don’t get any faster.
