For best results distance runners should have a BMI on the lower end of the healthy range. If you’re serious about improving your performance over <1500m having a BMI of ~25 will be the biggest impediment. Not sure what the range is but I think your average elite marathon runner will have a BMI of 18-20. Sport with a high mobility requirement? Things like weightlifting, gymnastics, ballet etc.
