What negative effect does excess fat have on a racing condition Whippet's performance?

Answer

It slows the elastic recoil of the back and reduces acceleration

Because the Whippet’s speed relies heavily on the elastic recoil provided by its arched loin and flexible spine, maintaining a lean physique is paramount for performance. Any accumulation of excess weight, referred to as extra fat, acts directly against this design principle by functioning as unnecessary ballast. This added mass impedes the rapid, elastic recoil mechanism of the back, which is essential for generating acceleration. Therefore, owners conditioning their Whippets for racing must actively monitor their body condition, often ensuring ribs are easily palpable beneath the skin, signaling the required level of leanness.
