You're almost there. Put \\s and the following [a-zA-Z]+ into a capturing or non-capturing group and make them to repeat one or more times by adding a + quantifier next to that group.

^[a-zA-Z]+(?:\s[a-zA-Z]+)+$

Example:

> /^[a-zA-Z]+(?:\s[a-zA-Z]+)+$/.test('real name')
true
> /^[a-zA-Z]+(?:\s[a-zA-Z]+)+$/.test('real name real and many words')
true
> /^[a-zA-Z]+(?:\s[a-zA-Z]+)+$/.test('name')
false
